ICD-10 code F43.1: Post-Traumatic Stress Disorder (PTSD)
Understanding ICD-10 Code F43.1 for Post-Traumatic Stress Disorder Post-traumatic stress disorder (PTSD) coding requires precision. The ICD-10-CM code F43.1 serves as the parent classification for PTSD, but clinicians cannot use it for insurance billing. Three specific subcodes-F43.10, F43.11, and F43.12-provide the granularity payers require for claim processing. These codes fall under the F43 category “Reaction […]
ICD-10-CM Stress codes: F43.0, F43.9, Z73.3 (2026)
Introduction to ICD-10-CM Stress Codes ICD-10-CM stress codes document stress-related diagnoses in mental health and primary care settings. These codes differentiate acute stress reactions, unspecified stress responses, and general stress presentations that don’t meet diagnostic criteria for specific anxiety or adjustment disorders. Clinicians treating patients with stress-related symptoms rely on these codes to ensure accurate […]
ICD-10 code Z30.46: Nexplanon Removal
ICD-10 Code Z30.46: Nexplanon Removal Overview Z30.46 (Encounter for surveillance of implantable subdermal contraceptive) is the primary ICD-10-CM code for documenting Nexplanon removal encounters. This code applies to all etonogestrel implant removal scenarios-whether routine removal at the three-year mark, early removal due to patient preference, or complication-driven extractions requiring imaging guidance. The code sits within […]
ICD-10-CM code E87.6: Hypokalemia (Potassium Deficiency)
What Is ICD-10-CM Code E87.6? ICD-10-CM code E87.6 defines hypokalemia, a condition characterised by abnormally low serum potassium levels (typically below 3.5 mEq/L). The code sits within the electrolyte imbalance disorders chapter (E70-E88) and serves as the primary diagnostic identifier for potassium deficiency in adults and children beyond the neonatal period. The CDC’s ICD-10-CM web […]
ICD-10 code F42: Obsessive-Compulsive Disorder (OCD)
Understanding ICD-10 Code for OCD Obsessive-compulsive disorder affects approximately 2-3% of the global population, yet coding it accurately remains one of the most misunderstood areas of mental health billing. The ICD-10-CM F42 code series captures the diagnosis, but selecting the right subcategory determines whether your claim processes smoothly or triggers a documentation review. Mental health […]
ICD-10 code M11.2: Other Chondrocalcinosis (Pseudogout)
Introduction to Pseudogout ICD-10 Coding Pseudogout-clinically known as calcium pyrophosphate deposition disease (CPPD)-presents a persistent coding challenge for rheumatology and orthopedic practices. The term “pseudogout” does not appear as an indexed entry in ICD-10-CM. Instead, coders must assign codes from the M11.2 category (Other chondrocalcinosis) to capture the diagnosis. This classification reflects the radiographic finding […]
Craniotomy ICD-10 code Z48.811: Aftercare, Complications & Billing
Craniotomy ICD-10: Introduction to Diagnosis Coding Craniotomy procedures require precise ICD-10-CM diagnosis coding to support medical necessity, guide treatment planning, and ensure appropriate reimbursement. Coders face a complex decision tree: Is this a postoperative follow-up visit, a traumatic brain injury requiring surgical intervention, or a complication case? The correct craniotomy ICD-10 code depends on clinical […]
ICD-10 code I25.10: Atherosclerotic Heart Disease of Native Coronary Artery Without Angina Pectoris
Introduction to ICD-10-CM Coronary Artery Disease Coding ICD-10-CM coronary artery disease coding requires precision. A single documentation detail-whether the patient experiences angina-determines which code applies. I25.10 identifies atherosclerotic heart disease of native coronary arteries without angina pectoris, distinguishing it from related codes in the I25.1 series. Clinics using claims management software must understand these distinctions […]
ICD-10 code N76.0: Acute Vaginitis (Bacterial Vaginosis)
Understanding Bacterial Vaginosis ICD-10 Codes Bacterial vaginosis represents one of the most common vaginal infections encountered in clinical practice, yet its coding remains frequently misunderstood. The ICD-10-CM classification system assigns N76.0 as the primary code for acute vaginitis caused by bacterial overgrowth, but proper assignment depends on clinical documentation that captures specific diagnostic criteria. Clinicians […]
ICD-10 code E11.00: Type 2 Diabetes with Hyperosmolarity
Introduction to Hyperosmolar Hyperglycemic State ICD-10 Coding Hyperosmolar hyperglycemic state (HHS) is a life-threatening diabetes complication that requires precise ICD-10-CM coding to support accurate diagnosis documentation and reimbursement. Clinicians encounter HHS most commonly in Type 2 diabetes patients, where severe hyperglycemia exceeds 600 mg/dL alongside marked hyperosmolarity without significant ketoacidosis. The primary code E11.00 designates […]
