CPT code 44238 – Unlisted intestinal laparoscopy procedure

Key takeaways

CPT Code 44238 covers laparoscopic procedures on the small or large intestine, excluding the rectum, that no code from 44180 to 44227 describes.

It is a laparoscopy code, so intestinal endoscopy and enteroscopy are reported with 44360-44408, never 44238.

Every claim needs an operative report and a comparable listed code, such as 44050 for an internal hernia repair.

Original Medicare generally needs no prior authorization for 44238, while many commercial and Medicare Advantage plans require it.

Pabau’s claims management software flags missing attachments before a 44238 claim is submitted.

CPT Code 44238: Official descriptor and definition

CPT Code 44238 is the unlisted code for a laparoscopic procedure on the intestine, excluding the rectum. Its full descriptor reads “Unlisted laparoscopy procedure, intestine (except rectum).” The American Medical Association (AMA) places it at the end of the Laparoscopy subsection of Intestines (Except Rectum), which runs from 44180 to 44238.

“Unlisted” does not mean unrecognized. It means the AMA has no dedicated descriptor yet for the laparoscopic technique the surgeon performed. Coders reach for 44238 only after confirming that no code from 44180 to 44227 captures the procedure.

• Code range: 44180-44238 (laparoscopy, intestines except rectum)
• Procedure type: Laparoscopic surgery on the small or large intestine, excluding the rectum
• Not covered: Intestinal endoscopy and enteroscopy, which have their own codes (44360-44408)
• Code status: Active, carrier-priced on the Medicare Physician Fee Schedule with no national rate
• Maintained by: American Medical Association (AMA) CPT Editorial Panel

Because 44238 carries no assigned relative value units (RVUs), it is priced by comparison to the closest listed code. Each Medicare Administrative Contractor (MAC) uses that comparison to decide what, if anything, to pay.

What does CPT Code 44238 cover?

CPT Code 44238 covers laparoscopic procedures on the small or large intestine, excluding the rectum, where no specific listed code describes the work. The example CPT Assistant and the American College of Surgeons (ACS) cite is laparoscopic repair of an internal hernia of the small intestine. It also fits a laparoscopic intestinal procedure that has an open-surgery code but no laparoscopic one.

Payers do not all agree on this code. Some ask for 44799 (unlisted procedure, small intestine) instead, so check the payer’s policy before you submit. Code 49659 is for abdominal wall hernias. CPT Assistant says it is not correct for an internal hernia, which goes to 44238.

Procedures that should not be reported under 44238:

• Intestinal endoscopy, enteroscopy, or ileoscopy (use the 44360-44408 family)
• Colonoscopy through the anus (use 45378-45398)
• Laparoscopic procedures on the rectum (use 45395-45402, or 45499 when no listed code fits)
• Diagnostic laparoscopy of the abdomen (use 49320)
• Any laparoscopic intestinal procedure that a code from 44180 to 44227 already describes
• Open small-intestine procedures with no listed code (use 44799)

The decision path below runs those exclusions in the order a coder checks them, so each “no” lands on the code that does apply.

If any listed code describes the procedure, the coder must use it. Choosing 44238 when a specific code exists is a leading cause of denial for unlisted claims.

Pabau, the practice management platform we build, tracks code assignments alongside documentation in its claims software for coders. It flags any claim where an unlisted code is selected without a comparable code noted.

CPT Code 44238 vs. related laparoscopic intestinal codes

Selecting the correct code starts with ruling out every listed alternative. The table below covers the listed codes in the same laparoscopy subsection, plus the unlisted and open codes most often confused with it.

The hierarchy is simple: If a listed code exists, use it. An unlisted code is always the option of last resort, never a coding shortcut.

When to use CPT Code 44238: Decision criteria

Three conditions must all be true before CPT Code 44238 is the correct choice.

1. The procedure was laparoscopic and on the intestine. The surgeon must have worked laparoscopically on the small or large intestine, excluding the rectum. A procedure done through an endoscope or an open incision belongs to a different code family.
2. No listed CPT code describes the procedure. The coder must review 44180-44227 and the wider digestive system section and confirm that no descriptor captures the work. Record this review in the claim narrative.
3. A comparable listed code can be identified. Payers require a listed code to use as a pricing benchmark. The physician or a certified coder picks the listed procedure most clinically similar to what was done. For a laparoscopic internal hernia repair, ACS suggests 44050.

Failing condition two is the most common coding error: Using 44238 because it is “close enough” when a listed code exists. According to the AMA CPT code set guidelines, unlisted codes are for procedures no specific code describes. Payers routinely deny an unlisted claim when a listed code applies.

Documentation requirements for CPT Code 44238

Missing or incomplete documentation is the primary cause of 44238 denials. A clean claim for an unlisted code needs more supporting material than any listed procedure. Every 44238 claim needs all four of the following before it leaves the practice.

Of the four, the operative report carries the most weight. It is the payer’s only record of what the surgeon did, and every clean claim for an unlisted procedure is built around it.

• Operative report: A complete, dictated operative note describing the procedure from port placement to closure. It should include the laparoscopic approach, findings, instruments used, and any complications. Summaries and brief notes are typically insufficient.
• Cover letter or narrative: A brief letter from the billing office, countersigned by the physician where payers require it. It explains why no listed code applies, cites the comparable code selected, and states the clinical rationale.
• Comparable listed CPT code: The specific code number and its descriptor must be explicitly identified. The payer uses this figure to determine payment. Omitting it almost guarantees a request for additional information or an outright denial.
• Supporting clinical notes: The pre-op history and physical (H&P) and the imaging that confirmed the diagnosis. Add pathology results if tissue was removed, plus any lab reports that establish medical necessity.

Prior authorization requirements for CPT Code 44238

Prior authorization for CPT Code 44238 depends on the payer. Original Medicare generally does not require prior authorization for unlisted procedure codes. It reviews the claim after the service instead, using the documentation you submit.

Many commercial payers and Medicare Advantage plans do require prior authorization for unlisted codes. Because 44238 has no preset payment rate, these plans review each case individually. Always verify the requirement with the specific plan before scheduling the procedure.

A prior authorization (PA) request for CPT Code 44238 typically includes:

• The specific procedure being requested, described in clinical terms
• The comparable listed CPT code and why it is being used as a benchmark
• Supporting clinical documentation (diagnosis, treatment history, medical necessity rationale)
• Anticipated date of service

When a plan has no request form of its own, a standard prior authorization form captures these details in one document.

Proceeding without authorization when a payer requires one results in a denial that is difficult to overturn on appeal. The payer’s position is procedural rather than clinical.

Medicare reimbursement for CPT Code 44238

Medicare has no national fee schedule rate for CPT Code 44238. The code is carrier-priced, so the MAC for the practice’s region sets payment case by case. It uses the comparable listed code the physician submits as a pricing reference. According to CMS Physician Fee Schedule guidance, the MAC reviews each unlisted claim individually before deciding on payment.

Pabau integrates with Claim.MD, a clearinghouse that routes claims to the correct MAC. The integration also supports the electronic remittance advice (ERA) workflow once a pricing determination comes back.

• Pricing mechanism: The MAC prices the claim by reference to the comparable listed code. Payment may be at, above, or below that rate, depending on the MAC’s clinical review.
• Required attachments: The operative report and a cover letter naming the comparable code must accompany the electronic claim.
• Medical necessity: CMS requires documentation that shows why the procedure was medically necessary. A code alone is not sufficient.
• Commercial payers: Payment terms vary. Some use the Medicare MAC rate as a reference, while others set their own fee.

NCCI bundling rules and modifier use for CPT Code 44238

The National Correct Coding Initiative (NCCI) governs which codes can and cannot be billed together. CMS updates NCCI edits quarterly, so check the current edit status before billing 44238 alongside other procedures. The CMS NCCI edits page publishes the edit tables and the NCCI Policy Manual. Chapter 6 of that manual covers digestive system procedures.

Key NCCI considerations for CPT Code 44238:

• Column one/column two edits: If 44238 is billed with another laparoscopic intestinal code from the same operative session, NCCI may bundle them. The column one code is the only one that pays unless a modifier unbundles them.
• Modifier 59 (Distinct Procedural Service): Apply when the 44238 procedure is separate and distinct from another procedure billed on the same date. The operative report must document the anatomical site, approach, or timing that distinguishes the two services.
• X-modifiers (XS, XE, XP, XU): Subsets of Modifier 59, used when payers require greater specificity. XS marks a separate structure, XE a separate encounter, XP a separate practitioner and XU an unusual non-overlapping service.
• Modifier 22 (Increased Procedural Services): Not appended to an unlisted code, because 44238 has no defined work value to increase. Describe the extra time and complexity in the cover letter instead.

Never apply a modifier defensively without documentation to support it. Unsupported modifier use creates audit risk and does not guarantee payment.

Common reasons CPT Code 44238 claims are denied

Unlisted codes attract more scrutiny than listed ones, because a reviewer prices each claim by hand. Knowing the exact cause of a denial shapes the appeal strategy. Our denial code reference lists the reason and remark codes that accompany each denial type below.

How to appeal a denied CPT Code 44238 claim

An unlisted claim has already been reviewed by hand once, so an appeal has to answer the payer’s specific objection. A structured denial management workflow recovers more revenue than ad-hoc resubmissions. Follow these steps in sequence, and use a medical appeal form to keep each packet consistent.

1. Identify the denial reason code. The Explanation of Benefits (EOB) or Electronic Remittance Advice (ERA) carries a CARC (Claim Adjustment Reason Code). It often carries a RARC (Remittance Advice Remark Code) too. The CARC tells you exactly why the payer declined. Match it to the denial table above to choose the correct rebuttal strategy.
2. Gather the appeal packet. Collect the full operative report, the physician’s attestation that no listed code describes the procedure, and the cover letter naming the comparable code. Add any supporting clinical documentation, such as pathology, pre-op notes, and imaging. If the denial was for lack of PA, also pull the correspondence showing when PA was requested.
3. Draft the appeal letter. Address the specific CARC. If the payer claims a listed code exists, identify each listed code you considered and document why it does not describe the procedure. If the payer wants 44799 instead, ask whether it will reprocess under that code. Name the comparable listed code and justify the pricing reference.
4. Submit within the appeal deadline. Medicare’s window for a first-level appeal (redetermination) is 120 days from receipt of the initial determination notice. Receipt is presumed to be five days after the notice date. Commercial payers vary, typically 60 to 180 days. Missing the window forfeits the right to appeal regardless of clinical merit.
5. Request peer-to-peer review. If the first-level appeal is denied, most payers allow the treating physician to speak directly with the payer’s medical director. This is most effective for medical necessity denials, where a clinical conversation often resolves what a paper appeal cannot.

How Pabau supports unlisted code claims

Many practices still track unlisted code claims in spreadsheets and email threads. A missing operative report or comparable code then surfaces only when the denial arrives, weeks after the procedure.

Pabau’s claims management software tracks which attachments each unlisted claim needs and flags any that are missing before submission. Claims then go out through the Claim.MD integration, and the ERA comes back into the same record.

The result is fewer denials for missing paperwork, and a complete file to support an appeal when a payer disputes the price.

Track unlisted code claims from submission to payment

Pabau’s claims management tools flag missing documentation, track comparable code submissions, and send claims through the Claim.MD integration. See how it works.

Conclusion

Treat 44238 as the code that remains once every listed option is ruled out. If a code from 44180 to 44227 describes the operative note, report that code and let the fee schedule price it.

When 44238 does apply, payment moves from a fee schedule to a reviewer. Send the operative report, a named comparable code and any PA approval with the first submission, and that reviewer has little reason to deny it.

The trade-off is time. An unlisted claim takes longer to build and longer to pay, so start the packet when the surgery is booked. Book a demo to see how Pabau keeps the operative report, comparable code and payer approval attached to every unlisted claim.
