CPT code 48140 – Distal pancreatectomy billing guide

Key takeaways

CPT code 48140 reports a distal subtotal pancreatectomy, with or without splenectomy, when no pancreaticojejunostomy is created. If the remnant is drained into the jejunum, the code is 48145.

CPT has no laparoscopic or robotic distal pancreatectomy code. A case completed that way is reported with unlisted code 48999 and 48140 as the comparator.

Splenectomy is included in 48140 by its descriptor, whatever the indication. Modifier 59 or XS on CPT 38100 is rarely supportable, so report substantial added work with modifier 22 instead.

The code carries a 90-day global surgery period. An unrelated E/M visit in that window needs modifier 24, and an unrelated procedure needs modifier 79.

Pabau’s claims management software submits 48140 claims through its Claim.MD integration and tracks each claim’s status from the patient record.

CPT code 48140: Official descriptor and procedure overview

CPT code 48140 is defined by the American Medical Association as: Pancreatectomy, distal subtotal, with or without splenectomy; without pancreaticojejunostomy. The phrase “with or without splenectomy” means the spleen’s fate is already accounted for inside the code. Separately billing a splenectomy on the same claim is almost always incorrect.

The second clause matters just as much. CPT 48140 applies only when the surgeon closes the pancreatic stump without an anastomosis. When the remnant is drained into a loop of jejunum (a pancreaticojejunostomy), the correct code is 48145.

The procedure targets the body and tail of the pancreas, leaving the head and the pancreaticoduodenal junction intact. That distinction separates 48140 from the Whipple procedure (CPT 48150-48154), which removes the pancreatic head with the duodenum and distal bile duct. The classic Whipple also removes part of the stomach, while the pylorus-preserving version does not.

• Code number: 48140
• Category: Surgery, Digestive System, Pancreas
• Approach: Open. CPT has no laparoscopic or robotic distal pancreatectomy code, so those cases go to unlisted code 48999
• Pancreatic remnant: Stump closed without a pancreaticojejunostomy (48145 when one is created)
• Spleen handling: With or without splenectomy, both covered
• Global period: 090 (90 days)
• Related codes: 48145, 48146, 48148, 48150-48155, and 48999 (see the code family table below)

Clinical indications: When is distal pancreatectomy coded?

Medical necessity for CPT code 48140 hinges on a documented diagnosis that justifies resection of the distal pancreas. The operative report and pre-operative notes must establish why the procedure was performed, and the linked ICD-10-CM code must be clinically appropriate.

CPT 48140 vs 48145: without vs with pancreaticojejunostomy

CPT 48140 and 48145 describe the same distal subtotal resection, with or without splenectomy. The only difference is what happens to the pancreatic remnant. Under 48140 the surgeon closes the stump, while under 48145 the remnant is anastomosed to a jejunal limb to drain the duct.

When a laparoscopic or robotic case is converted to open, report the open code that matches the remnant handling and document the reason for conversion.

A case completed laparoscopically has no dedicated code. Report 48999 and send the operative note with a cover letter naming the comparator code, since payers price the unlisted code case by case. The decision path below reduces the choice to two facts in the operative note.

Pancreatectomy code family: Neighboring codes and when they apply

Codes 48140 through 48155 cover the pancreatectomy variants, and none of them describes a laparoscopic approach. Each one turns on a detail of the operative report, which is why medical billing fundamentals start with reading the note before choosing a code.

Does CPT 48140 include splenectomy? Bundling and unbundling rules

The short answer is yes, splenectomy is bundled into CPT code 48140. The descriptor explicitly states “with or without splenectomy,” which signals that the spleen’s removal or preservation is already priced into the procedure. Separately billing CPT 38100 (splenectomy) alongside 48140 triggers an NCCI edit and will be denied on most claims.

Modifier 59, or its subset modifier XS, is rarely supportable on 38100 here. The descriptor covers splenectomy for any indication, so a separate splenic diagnosis does not make it a distinct service.

When the splenectomy added substantial work, append modifier 22 to 48140 and attach a cover letter that quantifies it. Verify the current NCCI edit before submitting, because edit tables change quarterly.

• Bundled (default): Splenectomy because the pancreatic tail is adherent to the spleen, to facilitate resection, or for tumor involvement. Never report 38100 separately for these
• Separate splenic pathology: Still covered by the descriptor, which includes splenectomy for any indication. Modifier 59 or XS is rarely supportable, so verify the current NCCI edit before submitting
• Substantial added work: Append modifier 22 to 48140 and attach a cover letter that quantifies the extra time and difficulty

Modifiers for CPT code 48140

Each modifier on a CPT code 48140 claim needs specific support in the operative report. The wrong modifier, or one without documentation, leads to a denial or a payer audit.

Medicare reimbursement for CPT code 48140: RVUs and payment rates

Medicare pays for CPT code 48140 under the Medicare Physician Fee Schedule using the resource-based relative value scale. The final payment amount is calculated as: total RVUs x Geographic Practice Cost Indices (GPCI) x conversion factor.

Use the CMS Physician Fee Schedule look-up tool to retrieve the current-year payment for your locality. Rates change with each annual MPFS update, so verify any figure here against the fee schedule for the billing year.

For the current-year work RVU, facility rate, and non-facility rate, look up CPT 48140 in the FastRVU 2026 lookup tool. As a major open abdominal surgery, 48140 carries a high work RVU, listed at 25.66 for 2026.

CMS resets the value each year, so check it for the billing year in question. Practices on Pabau, the practice management platform we build, send 48140 claims through Claim.MD, which submits electronic claims to thousands of US payers.

• Facility rate: Applies when the procedure is performed in a hospital or ambulatory surgical center
• Non-facility rate: Applies in an office setting, which rarely fits a major open surgery like 48140
• GPCI adjustment: Geographic multipliers shift the final rate up or down based on local resource costs
• Global period indicator: 090 (90-day global). Post-op visits and routine surgical follow-up are included in the fee

Global surgery period for CPT code 48140

CPT code 48140 carries a 90-day global surgery period. Routine pre-operative evaluation the day before, the surgery itself, and routine post-operative care for 90 days are all bundled into the single 48140 payment. Billing a separate E/M visit during this window for a complication or follow-up that is directly related to the pancreatectomy will be denied.

Three modifiers allow for separately billable services during the global period:

• Modifier 24: Unrelated E/M service during the postoperative period. The E/M diagnosis must be clearly unrelated to the pancreatectomy and documented as such
• Modifier 79: Unrelated procedure during the postoperative period, used when an unrelated condition needs separate surgery within the 90-day window
• Modifier 78: Unplanned return to the operating room for a related complication. Medicare pays the intraoperative portion only, and no new global period starts. Complications treated without a return to the OR stay in the global fee

Documentation requirements for CPT code 48140

The operative report is the primary audit target for CPT code 48140. Payers and the OIG both flag high-value open abdominal surgeries for documentation review. Incomplete op reports are the most common reason a paid claim is later recouped. A superbill for a pancreatectomy is only as strong as the clinical record behind it.

The operative report must contain all of the following to support CPT 48140 on audit. Submitting a clean claim starts with confirming every element before the claim leaves the practice.

• Surgical approach: Open laparotomy, or a laparoscopic start converted to open with the reason recorded. A case finished laparoscopically goes to 48999
• Pancreatic remnant: Whether the stump was closed (48140) or a pancreaticojejunostomy was created (48145)
• Anatomical extent: Which portion of the pancreas was resected (body, tail, or both), with the line of transection described
• Spleen disposition: Whether the spleen was preserved or removed, and the clinical reason for either decision
• Intraoperative findings: Tumor size, location, and involvement of surrounding structures
• Vascular control: Description of how the splenic vessels and pancreatic duct were managed
• Specimen handling: How the specimen was oriented and sent to pathology
• Pathology correlation: Final pathology report confirming diagnosis aligns with the ICD-10-CM code used for billing
• Surgeon attestation: Signature and date confirming the report accurately reflects what was performed

Prior authorization requirements for CPT code 48140

Traditional Medicare (Parts A and B) does not require prior authorization for most surgical procedures, including CPT code 48140. Medicare Advantage plans and commercial insurers vary significantly, and medical billing compliance requires verifying each plan’s authorization requirements before scheduling.

Commercial payers and Medicare Advantage plans that require prior authorization for 48140 usually ask for this clinical documentation:

• Imaging studies (CT, MRI, EUS) confirming the lesion location, size, and characteristics
• Pathology or biopsy results, where available
• Documentation of failed conservative management (for chronic pancreatitis cases)
• Surgeon’s clinical letter describing the planned resection and approach
• The specific ICD-10-CM code supporting the diagnosis

Prior authorization rules change with each plan year and vary by payer, so never assume approval is not required. Call the payer’s provider line or check the payer portal to confirm. A claim denied for missing prior authorization on a surgery of this magnitude is exceptionally difficult to appeal successfully.

Common denial reasons for CPT 48140 claims and how to appeal

CPT code 48140 denials follow predictable patterns. Knowing them in advance means a biller can catch the error before submission rather than managing an appeal after denial.

Understanding denial management workflows at the practice level reduces the average days in accounts receivable for these high-value claims. Review common denial codes to map each remittance advice code to the underlying billing error.

• Wrong code in the distal family: 48140 billed for a case that included a pancreaticojejunostomy (48145), or for a laparoscopic case that belongs under 48999. Refile with the correct code if within the timely filing window.
• Splenectomy unbundling error: CPT 38100 submitted alongside 48140. The descriptor includes splenectomy, so modifier 59 or XS is rarely supportable. Remove 38100 and, where the splenectomy added substantial work, refile 48140 with modifier 22 and a cover letter.
• ICD-10 linkage failure: Diagnosis code does not support the procedure (e.g., a benign indication code linked to a claim with modifier 22 for complexity). Correct the ICD-10-CM code to match pathology findings and resubmit.
• Missing prior authorization: No PA obtained for a Medicare Advantage or commercial plan that required one. Appeal with a retrospective authorization request; success depends on clinical urgency and plan policy.
• Incomplete operative report: Payer cannot confirm the approach, the remnant handling, or the spleen disposition. Provide the complete op report on appeal with the relevant sections flagged.
• Modifier 22 without a supporting narrative: The claim carries modifier 22 but lacks the separate narrative explaining why the procedure was significantly more complex. Attach the narrative letter and refile.

How Pabau supports accurate billing for CPT code 48140

Surgical practices often keep pre-operative imaging, operative notes, and claims in separate systems. That split is where remnant-handling and splenectomy details drop out before the claim is coded.

Pabau keeps them together in one patient record. Customizable note templates can prompt the surgeon to record whether a pancreaticojejunostomy was created and why the spleen was removed or kept.

The claim then goes out electronically through Pabau’s Claim.MD integration. Your team gets less manual claims management, following each claim’s status without leaving the patient record.

Streamline surgical billing from the OR to the payer

Pabau keeps operative notes and claims in one patient record, then submits claims through Claim.MD. Your billing team spends less time chasing missing details.

Conclusion

Read the operative note for two facts before choosing the code: how the pancreatic remnant was handled and how the procedure was performed. A closed stump supports 48140, and a pancreaticojejunostomy moves the claim to 48145. A case finished laparoscopically goes to 48999.

Splenectomy stays inside the code whatever the reason for it, and extra work belongs on modifier 22 rather than a second line for 38100. A coder who confirms these facts before submission avoids the denials that cost the most on high-value surgical cases.
