Understanding ICD-10 Liver Cirrhosis Codes

Liver cirrhosis coding in ICD-10-CM centres on three primary codes that reflect both the underlying cause and clinical presentation. Accurate code selection requires clear documentation of etiology, because the distinction between alcoholic and non-alcoholic cirrhosis determines reimbursement, treatment pathways, and data integrity in population health studies. According to the CMS ICD-10 coding system, approximately 4.5 million adults in the United States live with chronic liver disease, making precise diagnostic coding essential for care coordination and resource planning.

The ICD-10 liver cirrhosis classification splits into etiology-specific categories. When the cause of cirrhosis remains unclear or inadequately documented, coders default to K74.60 (Unspecified Cirrhosis of Liver). This contrasts with K74.69 (Other Cirrhosis of Liver), which applies when cirrhosis results from a known but non-alcoholic cause such as primary biliary cholangitis or cryptogenic cirrhosis. Alcoholic cirrhosis receives separate coding under K70.30 and K70.31, reflecting whether ascites is present. Each code carries distinct clinical and billing implications that shape treatment documentation and claims submission workflows.

ICD-10-CM Code K74.60: Unspecified Cirrhosis of Liver

K74.60 applies when clinical documentation confirms liver cirrhosis but fails to identify the underlying cause. This code functions as the default selection when no other etiology-specific code meets the clinical scenario. Common situations requiring K74.60 include incomplete patient histories, ambiguous diagnostic findings where multiple potential causes exist but none are confirmed, or cases where the cirrhotic process has progressed beyond the point of identifying an original trigger. The code description in the official CDC ICD-10-CM tool characterises it as unspecified cirrhosis without reference to causative agents.

Clinically, K74.60 represents a diagnosis of exclusion. Before assigning it, coders must verify that documentation does not contain sufficient information to support more specific codes such as K70.30 for alcoholic cirrhosis, K74.3 for primary biliary cholangitis, or K74.4 for secondary biliary cirrhosis. The code applies regardless of whether cirrhosis is compensated or decompensated, though the presence of complications requires additional coding to capture the full clinical picture. Insurers typically accept K74.60 when query responses from clinicians confirm that etiology remains genuinely undetermined after appropriate diagnostic workup.

Clinical Definition and Scope

K74.60 encompasses replacement of liver parenchyma with fibrous tissue and regenerative nodules resulting from chronic hepatic injury. The diagnosis requires histological or imaging evidence of cirrhotic changes, but lacks documentation linking these changes to alcohol, viral hepatitis, metabolic disease, or other identifiable causes. Patients coded under K74.60 often present with portal hypertension, reduced hepatic synthetic function, or imaging findings consistent with cirrhosis, yet their medical records contain no definitive etiological diagnosis. This scenario occurs frequently in patients with longstanding comorbidities, incomplete substance use histories, or late-stage presentations where the original liver injury has become obscured by advanced scarring.

When to Query for Specificity

Coders should initiate queries when documentation mentions alcohol use, viral hepatitis markers, metabolic syndrome, or any potential cirrhosis trigger without definitively stating causation. A query template should ask: “Does the patient’s cirrhosis result from alcohol use, viral hepatitis (B15-B19), non-alcoholic fatty liver disease, or another identifiable cause? If none, please confirm that etiology remains undetermined despite appropriate diagnostic evaluation.” This clarification allows assignment of a more specific code, improving data accuracy and potentially altering DRG assignment. According to AAPC coding guidance, specificity in etiology documentation directly impacts medical necessity justification and audit defense.

Liver Cirrhosis Code Chart: K74.60, K74.69, K70.30, and K70.31

ICD-10-CM Code Description Use When Excludes
K74.60 Unspecified Cirrhosis of Liver Etiology undocumented or unknown after workup Alcoholic cirrhosis (K70.30), congenital cirrhosis (Q44.2-Q44.7)
K74.69 Other Cirrhosis of Liver Cirrhosis from known non-alcoholic cause not elsewhere classified Alcoholic cirrhosis (K70.30), primary biliary cholangitis (K74.3)
K70.30 Alcoholic Cirrhosis of Liver Without Ascites Documented alcohol-induced cirrhosis, no ascites present Alcoholic fibrosis (K70.2), alcoholic cirrhosis with ascites (K70.31)
K70.31 Alcoholic Cirrhosis of Liver With Ascites Documented alcohol-induced cirrhosis with concurrent ascites Alcoholic cirrhosis without ascites (K70.30), other cirrhosis with ascites

This chart reflects the hierarchical structure of ICD-10-CM cirrhosis coding. K70.30 and K70.31 fall under the K70 category for alcoholic liver disease, while K74.60 and K74.69 reside in the K74 category for fibrosis and cirrhosis of liver. The ascites distinction in alcoholic cirrhosis (K70.30 vs K70.31) has direct clinical significance, as ascites presence indicates decompensation and changes treatment intensity. Documentation must explicitly state “alcoholic cirrhosis” for K70.30/K70.31 assignment; suspicion of alcohol use without confirmation defaults to K74.60. The Excludes1 notation under K74.60 means that alcoholic cirrhosis (K70.30) cannot be coded simultaneously with K74.60 on the same encounter-one code supersedes the other based on documented etiology.

ICD-10-CM Code K74.69: Other Cirrhosis of Liver

K74.69 captures cirrhosis cases where a known non-alcoholic etiology exists but no more specific ICD-10-CM code applies. This includes cryptogenic cirrhosis (cirrhosis with no identifiable cause after extensive workup), autoimmune hepatitis-related cirrhosis not coded elsewhere, and cirrhosis resulting from drug-induced liver injury when the specific agent or mechanism lacks a dedicated code. The distinction between K74.60 and K74.69 hinges on whether documentation indicates an investigated but unidentifiable cause (K74.60) versus a documented non-alcoholic cause that simply lacks a unique code (K74.69). In practice, K74.69 serves as a catch-all for uncommon or multifactorial non-alcoholic cirrhosis presentations.

Cryptogenic cirrhosis represents the most common scenario for K74.69 assignment. Patients with cryptogenic cirrhosis have undergone testing for viral hepatitis, autoimmune markers, metabolic liver disease, and alcohol use, yet no definitive cause emerges. Over time, some cryptogenic cases are reclassified as non-alcoholic steatohepatitis (NASH) cirrhosis after retrospective analysis reveals metabolic risk factors, but until that reclassification occurs, K74.69 remains appropriate. The CMS coding guidelines specify that “other” categories like K74.69 should only be used when a more specific code does not exist, reinforcing the need for thorough documentation review before code assignment.

Documentation Requirements for K74.69

Assigning K74.69 requires explicit documentation that cirrhosis resulted from a non-alcoholic cause. The medical record should contain statements such as “cirrhosis secondary to cryptogenic liver disease,” “cirrhosis due to drug-induced hepatotoxicity from [specific agent],” or “cirrhosis of unclear origin, extensive workup negative for viral, alcoholic, and autoimmune etiologies.” Without this specificity, K74.60 remains the safer default. Coding audits frequently challenge K74.69 assignments when documentation merely states “cirrhosis” without any etiological context, as this lacks the justification for selecting “other” over “unspecified.” Practices using integrated claims management software can build automated prompts that flag cirrhosis diagnoses lacking etiology details, reducing K74.60/K74.69 misassignment rates.

Pro Tip

Run monthly audits of K74.60 and K74.69 claims to identify documentation gaps. Create a query template that asks clinicians: ‘Does this patient’s cirrhosis result from alcohol, viral hepatitis, NASH, autoimmune disease, drug toxicity, or another identifiable cause? If none, please document that extensive workup was negative.’ This single query resolves most unspecified vs other cirrhosis coding dilemmas and strengthens audit defense when insurers challenge code specificity.

Alcoholic Cirrhosis ICD-10 Codes: K70.30 and K70.31

Alcoholic cirrhosis codes split based solely on ascites presence. K70.30 applies when documentation confirms alcohol-induced cirrhosis without concurrent ascites, while K70.31 applies when ascites complicates alcoholic cirrhosis. The distinction matters clinically because ascites signals hepatic decompensation, typically requiring diuretic therapy, sodium restriction, and increased monitoring for spontaneous bacterial peritonitis. From a coding perspective, the ascites modifier changes the code’s specificity and potentially impacts DRG assignment, as K70.31 may trigger higher acuity classifications compared to K70.30. Both codes require explicit documentation of alcohol as the cirrhosis cause; suspicion or patient-reported alcohol use without clinical attribution defaults to K74.60.

The Excludes1 notation under K70.30 prevents dual coding of alcoholic cirrhosis with hepatic encephalopathy, variceal hemorrhage, or other complications within the same K70 category. These complications receive additional codes from their respective chapters (e.g., K72.91 for hepatic encephalopathy, I85.01 for esophageal varices with bleeding). However, coders must sequence codes correctly-the cirrhosis code typically serves as the principal diagnosis, with complications listed as secondary diagnoses to reflect the clinical cascade. According to CMS ICD-10-CM guidelines, complications of cirrhosis should be coded separately even when they are direct consequences of the underlying liver disease, as this approach provides granular data for severity tracking and resource allocation.

ICD-10 Code K70.30: Alcoholic Cirrhosis Without Ascites

K70.30 indicates compensated alcoholic cirrhosis or decompensated alcoholic cirrhosis without fluid accumulation. The code applies when documentation explicitly states alcoholic cirrhosis and physical examination or imaging confirms absence of ascites. Common clinical scenarios include patients with alcohol use disorder histories, elevated liver enzymes, imaging evidence of cirrhosis, and no clinical or radiographic signs of ascitic fluid. The absence of ascites does not imply mild disease-patients may have portal hypertension, esophageal varices, or hepatic encephalopathy without ascites, requiring separate coding for each complication. K70.30 serves as the foundation diagnosis, with additional codes layered on to reflect the full clinical complexity.

ICD-10 Code K70.31: Alcoholic Cirrhosis With Ascites

K70.31 captures alcoholic cirrhosis complicated by ascites, a hallmark of hepatic decompensation. Documentation must explicitly mention both alcoholic etiology and ascites presence, typically supported by physical examination findings (shifting dullness, fluid wave) or imaging reports (ultrasound, CT, or MRI showing intraperitoneal fluid). The ascites itself does not require a separate code when K70.31 is assigned, as the code inherently includes the complication. However, if ascites results from a cause other than cirrhosis (e.g., peritoneal carcinomatosis, nephrotic syndrome), K70.31 would be inappropriate-the ascites would receive its own code alongside the underlying cause. Practices using digital intake forms can capture ascites status systematically during each encounter, ensuring coders have access to the information needed for accurate K70.30 vs K70.31 selection.

Pabau clinical workflow

Cirrhosis Complication Coding and Sequencing

Cirrhosis rarely presents as an isolated diagnosis. Portal hypertension, esophageal varices, hepatic encephalopathy, hepatorenal syndrome, and spontaneous bacterial peritonitis commonly accompany advanced liver disease, each requiring separate ICD-10-CM codes to reflect clinical severity and treatment complexity. The principal diagnosis remains the cirrhosis code (K74.60, K74.69, K70.30, or K70.31), with complications listed as secondary diagnoses. This sequencing follows CDC ICD-10-CM official guidelines, which dictate that the underlying condition takes precedence unless the encounter’s primary focus is managing a specific complication. Correct sequencing impacts DRG assignment and reimbursement, as higher acuity secondary diagnoses elevate the case’s complexity and resource consumption profile.

Hepatic encephalopathy receives code K72.91 when documentation describes altered mental status, asterixis, or confusion attributable to liver dysfunction. Esophageal varices without bleeding use I85.00, while bleeding varices require I85.01. Hepatorenal syndrome, a functional kidney injury complicating cirrhosis, uses K76.7. Spontaneous bacterial peritonitis, an infection of pre-existing ascites, codes to K65.2. Each complication code adds specificity to the clinical picture and justifies additional interventions, diagnostic tests, and monitoring intensity. Coders must avoid using complication codes that are already embedded in the cirrhosis diagnosis-for instance, ascites is inherent in K70.31, so R18.8 (other ascites) would be redundant. However, if a patient with K70.30 (no ascites) later develops ascites during the encounter, the coder should switch to K70.31 rather than add R18.8.

Portal Hypertension and Varices

Portal hypertension (K76.6) and esophageal varices (I85.00 or I85.01) frequently accompany cirrhosis and require explicit documentation for code assignment. Portal hypertension results from increased resistance to blood flow through the cirrhotic liver, causing venous dilation in the esophagus, stomach, and rectum. Coders should look for documentation of portal pressures measured via hepatic vein catheterisation, imaging reports describing portosystemic collaterals, or clinical notes mentioning splenomegaly and thrombocytopenia as indirect signs of portal hypertension. Esophageal varices require endoscopic confirmation or CT/MRI findings; the presence or absence of bleeding determines whether I85.00 (without bleeding) or I85.01 (with bleeding) applies. Bleeding varices trigger acute intervention coding and significantly elevate DRG weights, making documentation of bleeding status essential for accurate reimbursement.

Hepatic Encephalopathy

Hepatic encephalopathy (K72.91) manifests as altered mental status ranging from mild confusion to coma, resulting from ammonia and other toxins bypassing the cirrhotic liver. Documentation should describe clinical signs such as asterixis, disorientation, somnolence, or personality changes, ideally graded using the West Haven criteria (Grade I through IV). The code applies regardless of whether encephalopathy is episodic or chronic, but documentation must explicitly attribute the mental status changes to liver dysfunction rather than other causes like medication effects, infection, or metabolic derangements. Practices using AI-powered clinical documentation can prompt clinicians to specify encephalopathy grade and triggering factors (e.g., infection, gastrointestinal bleeding, medication non-compliance) during note generation, improving code specificity and supporting medical necessity for lactulose, rifaximin, or other encephalopathy-targeted therapies.

Pro Tip

Track complication coding patterns quarterly by comparing cirrhosis claims with and without secondary diagnosis codes for portal hypertension, varices, and encephalopathy. If your practice consistently codes cirrhosis without complications despite treating advanced liver disease, documentation templates may need revision. Add structured fields for ascites status, variceal screening results, and mental status assessment to ensure complications are captured at every encounter.

Viral Hepatitis Co-Coding with Cirrhosis

Cirrhosis resulting from chronic viral hepatitis requires dual coding-one code for cirrhosis (typically K74.60 or K74.69) and a second code from B15-B19 for the specific viral hepatitis type. Chronic hepatitis B cirrhosis uses B18.1 (Chronic Viral Hepatitis B Without Delta-Agent) alongside the cirrhosis code, while chronic hepatitis C cirrhosis pairs with B18.2 (Chronic Viral Hepatitis C). This dual coding approach captures both the underlying viral infection and its long-term hepatic consequence. According to the CMS ICD-10-CM guidelines, when cirrhosis is a direct sequela of documented viral hepatitis, both codes must appear on the claim to reflect the complete diagnostic picture and support antiviral therapy medical necessity.

Code sequencing for viral hepatitis cirrhosis depends on the encounter’s primary focus. If the visit centres on managing cirrhotic complications (ascites, encephalopathy, variceal screening), the cirrhosis code sequences first, with the hepatitis code as secondary. If the encounter focuses on antiviral therapy initiation, monitoring, or adjustment, the hepatitis code may sequence first, with cirrhosis as a secondary diagnosis justifying treatment urgency. Documentation should explicitly state the relationship between viral hepatitis and cirrhosis-phrases like “cirrhosis secondary to chronic hepatitis C” or “hepatitis B-related cirrhosis” clarify causation and guide code selection. Without this explicit linkage, coders may default to K74.60 without viral hepatitis co-coding, losing the opportunity to capture the full etiology and justify antiviral coverage.

Hepatitis B Cirrhosis Coding

Chronic hepatitis B cirrhosis requires K74.60 (if unspecified) or K74.69 (if documented as hepatitis B cirrhosis) paired with B18.1 (Chronic Viral Hepatitis B Without Delta-Agent). If delta-agent (hepatitis D) co-infection is present, B18.0 (Chronic Viral Hepatitis B With Delta-Agent) replaces B18.1. The presence of cirrhosis in hepatitis B patients influences antiviral therapy decisions, as international guidelines recommend treatment for all cirrhotic hepatitis B patients regardless of viral load or ALT levels. Documentation should specify hepatitis B surface antigen (HBsAg) positivity, viral load results, and the presence or absence of delta-agent co-infection to ensure accurate code assignment and justify the therapeutic approach.

Hepatitis C Cirrhosis Coding

Hepatitis C cirrhosis pairs K74.60 or K74.69 with B18.2 (Chronic Viral Hepatitis C). The advent of direct-acting antivirals (DAAs) has made hepatitis C curable even in cirrhotic patients, but documentation must clarify whether the patient has active viremia (requiring antiviral treatment) or sustained virologic response (SVR, indicating cured infection). Patients with SVR and residual cirrhosis still code with both the cirrhosis code and B18.2, as the hepatitis C infection’s historical presence caused the cirrhosis even though current viremia is absent. This dual coding supports ongoing monitoring for hepatocellular carcinoma and variceal screening, which remain indicated in patients with hepatitis C-related cirrhosis regardless of SVR status.

Documentation Requirements for Cirrhosis Coding

Accurate cirrhosis coding begins with comprehensive clinical documentation that addresses etiology, compensated vs decompensated status, presence or absence of ascites, and any complications. At minimum, documentation should state: (1) the diagnosis of cirrhosis confirmed by biopsy, imaging, or clinical criteria; (2) the identified or investigated cause (alcohol, viral hepatitis, NASH, autoimmune, cryptogenic, or unknown); (3) whether ascites is present; and (4) any complications such as portal hypertension, varices, encephalopathy, or hepatorenal syndrome. Without this foundational information, coders must query clinicians, delaying claim submission and increasing denial risk. The CDC ICD-10-CM tool provides official code definitions and inclusion/exclusion notes that coders reference when documentation ambiguity arises.

Etiology documentation represents the most frequent gap. Phrases like “cirrhosis, likely related to alcohol” or “cirrhosis with history of hepatitis C” lack the definitiveness required for K70.30 or hepatitis C co-coding. Instead, documentation should state “alcoholic cirrhosis” or “cirrhosis secondary to chronic hepatitis C infection.” When etiology remains uncertain after workup, the note should document the diagnostic steps taken (viral serology, autoimmune panels, metabolic screening) and conclude with “etiology undetermined despite extensive evaluation,” justifying K74.60 assignment. Decompensation status requires explicit mention of ascites, encephalopathy, variceal hemorrhage, or jaundice, as these findings determine code specificity and treatment intensity. Practices adopting structured digital intake forms with mandatory fields for etiology, ascites status, and complications report fewer coding queries and faster claim adjudication.

Query Templates for Etiology Clarification

When documentation lacks etiology details, coders should use standardised query templates to obtain clarification without leading the clinician toward a specific diagnosis. An effective query asks: “Documentation indicates liver cirrhosis. Please clarify: (1) Is this cirrhosis caused by alcohol use? (2) Is it related to viral hepatitis (specify type if yes)? (3) Is it secondary to NASH, autoimmune hepatitis, or another identifiable cause? (4) If the cause is unknown, please confirm that appropriate diagnostic workup was performed and no etiology was identified.” This format allows clinicians to select the most accurate option based on clinical knowledge, supporting code specificity without compromising documentation integrity. Queries should be initiated within 24-48 hours of encounter completion to ensure clinicians’ memories remain fresh and responses are timely.

Compensated vs Decompensated Status

ICD-10-CM does not have separate codes for compensated and decompensated cirrhosis; instead, decompensation status is inferred through complication coding. Compensated cirrhosis refers to liver scarring without major complications-patients may have fatigue and mild portal hypertension but no ascites, encephalopathy, or variceal bleeding. Decompensated cirrhosis manifests with one or more of these complications, signalling advanced liver failure and higher mortality risk. Documentation should explicitly state “compensated cirrhosis” or “decompensated cirrhosis with [complication]” to guide code assignment. When decompensation is present, coders assign the base cirrhosis code plus additional codes for each complication (e.g., K70.31 for alcoholic cirrhosis with ascites plus K72.91 for encephalopathy plus I85.01 for bleeding varices). This layered coding approach reflects the clinical severity and justifies intensive management, including potential liver transplant evaluation.

Common Cirrhosis Coding Errors and How to Avoid Them

Coding errors in cirrhosis documentation typically stem from incomplete etiology documentation, failure to code complications separately, incorrect code sequencing, or confusion between K74.60 and K74.69. One frequent error involves using K74.60 when documentation mentions alcohol use without explicitly stating alcoholic cirrhosis-coders may assume causation when the clinician intended to note alcohol as a risk factor rather than the confirmed etiology. This leads to incorrect code selection, as K74.60 should only apply when etiology is genuinely unspecified. Another common mistake is coding ascites separately using R18.8 when K70.31 already includes ascites as part of the code definition, resulting in redundant coding that insurers may reject or unbundle. Regular coding audits focusing on cirrhosis claims can identify these patterns and guide targeted documentation improvement initiatives.

Failure to code complications represents another major error. Coders may assign K70.30 for alcoholic cirrhosis without adding codes for portal hypertension (K76.6), esophageal varices (I85.00 or I85.01), or hepatic encephalopathy (K72.91), even when clinical notes describe these complications. This undercoding reduces case complexity scoring, lowers reimbursement, and fails to capture the true resource consumption of cirrhosis management. To prevent this, practices should implement coding protocols that require coders to review the entire encounter note for complication keywords (ascites, encephalopathy, varices, portal hypertension, jaundice) before finalising the claim. Automated coding assistance tools within integrated EHR and billing platforms can flag cirrhosis diagnoses lacking expected secondary codes, prompting coders to verify whether complications are present but undocumented or genuinely absent.

Error: Using K74.60 When K70.30 Applies

This error occurs when documentation mentions alcohol use alongside cirrhosis but does not explicitly label it as alcoholic cirrhosis. For example, a note stating “Patient has liver cirrhosis. History includes 30 years of heavy alcohol consumption” may lead coders to assume alcoholic etiology, but without the phrase “alcoholic cirrhosis” or “cirrhosis due to alcohol,” K74.60 is technically correct per coding rules. However, from a clinical and audit perspective, this represents a documentation gap rather than a coding error. The solution lies in clinician education: providers should be trained to write “alcoholic cirrhosis” when alcohol is the confirmed cause, and coders should query ambiguous documentation rather than make assumptions. This single documentation improvement shifts claims from K74.60 to K70.30, which may impact DRG assignment and better reflect the patient’s risk profile for treatment planning.

Error: Failing to Code Viral Hepatitis Alongside Cirrhosis

When cirrhosis results from chronic viral hepatitis, coders must assign both the cirrhosis code (K74.60 or K74.69) and the hepatitis code (B18.1 for hepatitis B, B18.2 for hepatitis C). Omitting the viral hepatitis code understates the patient’s condition and may jeopardise medical necessity justification for antiviral therapies. This error often occurs when coders focus solely on the primary diagnosis (cirrhosis) without reviewing the problem list or medication list for antiviral agents. To prevent this, coding workflows should include a step where coders check for any B15-B19 codes on the patient’s problem list and cross-reference them with the current encounter diagnosis. If viral hepatitis is active but not coded, the coder should query the provider to confirm whether the hepatitis remains current and contributory to the cirrhosis diagnosis.

DRG Impact and Reimbursement Considerations

Cirrhosis code selection and complication coding directly influence DRG assignment, which determines inpatient reimbursement amounts. According to the CMS MS-DRG v38.0 Definitions Manual, cirrhosis-related admissions typically fall into DRG 432 (Cirrhosis and Alcoholic Hepatitis with MCC) or DRG 433 (Cirrhosis and Alcoholic Hepatitis with CC), depending on the presence of major complications or comorbidities (MCC) such as hepatic encephalopathy, variceal hemorrhage, or hepatorenal syndrome. The difference in reimbursement between DRG 432 and DRG 433 can be substantial-hospitals with accurate complication coding receive higher payments that reflect the true cost of managing decompensated cirrhosis, while undercoded claims result in lower DRG assignments and financial losses.

Outpatient coding for cirrhosis does not use DRGs, but accurate coding remains critical for risk adjustment, quality reporting, and value-based care metrics. Commercial insurers and Medicare Advantage plans use diagnosis codes to calculate hierarchical condition category (HCC) scores, which predict healthcare costs and determine capitation payments. Cirrhosis codes (particularly K70.30, K70.31, and K74.69) carry HCC weights that increase predicted costs, resulting in higher capitation payments to providers managing cirrhotic patients. Undercoding cirrhosis in outpatient settings leaves money on the table and fails to capture the patient’s true acuity in population health risk stratification models. Practices participating in value-based contracts should prioritise cirrhosis coding accuracy as part of broader risk adjustment optimisation strategies, using practice analytics dashboards to track HCC capture rates and identify documentation gaps.

Major Complication and Comorbidity (MCC) Codes

MCC codes elevate DRG assignments and reimbursement for inpatient cirrhosis admissions. Hepatic encephalopathy (K72.91), hepatorenal syndrome (K76.7), and variceal hemorrhage (I85.01) all qualify as MCCs when documented appropriately. To qualify as an MCC, the complication must be present on admission or develop during the encounter and require clinical intervention or monitoring. Documentation must describe the complication’s clinical manifestations, diagnostic findings, and treatment response-generic statements like “possible encephalopathy” or “mild confusion” lack the specificity needed for MCC coding. Instead, notes should state “hepatic encephalopathy Grade II with asterixis and disorientation, treated with lactulose” to clearly justify K72.91 assignment and MCC status. Coding compliance programs should regularly audit cirrhosis admissions to ensure MCCs are captured whenever clinically present, maximising appropriate reimbursement while maintaining documentation integrity.

Frequently Asked Questions

How do I code cirrhosis with ascites?

If the cirrhosis is alcoholic in origin, use K70.31 (Alcoholic Cirrhosis of Liver With Ascites). For non-alcoholic cirrhosis with ascites, use the appropriate cirrhosis code (K74.60 or K74.69) and do not add a separate ascites code-document ascites in the clinical note to justify diuretic therapy and sodium restriction. For viral hepatitis cirrhosis with ascites, pair the cirrhosis code with B18.1 (hepatitis B) or B18.2 (hepatitis C) and document ascites presence to support treatment intensity.

What is the difference between K74.60 and K74.69?

K74.60 (Unspecified Cirrhosis of Liver) applies when the cause of cirrhosis is unknown or undocumented after appropriate workup. K74.69 (Other Cirrhosis of Liver) applies when cirrhosis results from a documented non-alcoholic cause that does not have a more specific code, such as cryptogenic cirrhosis or drug-induced cirrhosis. Use K74.60 when etiology is genuinely unknown despite investigation, and K74.69 when a non-alcoholic cause is identified but lacks a dedicated ICD-10-CM code.

Do I need to code hepatic encephalopathy separately from cirrhosis?

Yes. Hepatic encephalopathy receives its own code (K72.91) as a secondary diagnosis whenever documented, regardless of the cirrhosis code used. The cirrhosis code (K70.30, K70.31, K74.60, or K74.69) serves as the principal diagnosis, and K72.91 is added as a secondary diagnosis to reflect the complication. Documentation should describe encephalopathy grade and clinical manifestations (confusion, asterixis, lethargy) to justify the code assignment.

Can I use K70.30 if the patient has a history of alcohol use but the provider does not explicitly state alcoholic cirrhosis?

No. K70.30 requires explicit documentation that the cirrhosis is caused by alcohol. If documentation only mentions alcohol use history without attributing cirrhosis to alcohol, use K74.60 (Unspecified Cirrhosis of Liver) and query the provider for clarification. Coders should not infer causation-the provider must document “alcoholic cirrhosis” or “cirrhosis due to alcohol” to justify K70.30 assignment.

How do I code decompensated cirrhosis?

ICD-10-CM does not have a specific code for decompensated cirrhosis. Instead, code the base cirrhosis diagnosis (K70.30, K70.31, K74.60, or K74.69) and add secondary diagnosis codes for each complication present: ascites (included in K70.31 for alcoholic cirrhosis, otherwise documented but not separately coded), hepatic encephalopathy (K72.91), variceal hemorrhage (I85.01), portal hypertension (K76.6), or hepatorenal syndrome (K76.7). The combination of cirrhosis code plus complication codes collectively represents decompensated status.

Should I code viral hepatitis if the patient has cirrhosis from hepatitis C?

Yes. When cirrhosis results from chronic viral hepatitis, assign both the cirrhosis code (K74.60 or K74.69) and the hepatitis code (B18.2 for chronic hepatitis C). This dual coding captures the underlying viral infection and its hepatic sequela, supporting antiviral therapy medical necessity and hepatocellular carcinoma surveillance. Documentation should explicitly link the hepatitis to the cirrhosis (e.g., “cirrhosis secondary to chronic hepatitis C”) to justify both codes on the same claim.
