CPT code 43281: Paraesophageal hernia billing guide

Key takeaways

CPT code 43281 covers laparoscopic repair of a paraesophageal hernia without mesh, and it includes the fundoplasty when one is performed.

Mesh status in the operative report is what separates 43281 from 43282.

The 2026 national Medicare payment is about $1,425, and CMS pays the same amount in an office setting.

Billing 43281 in the same session as sleeve gastrectomy (43775) or gastric bypass (43644) invites a bundling denial.

Practice management software like Pabau keeps the operative note, the procedure code, and the claim on one client record.

CPT code 43281 covers laparoscopic repair of a paraesophageal hernia performed without mesh. The descriptor also bundles the fundoplasty, when the surgeon performs one. So one fact decides the code, and that fact is mesh status. No mesh means 43281. Mesh means 43282.

Pick the wrong one and about $1,425 in Medicare payment goes into a reclassification appeal. That happens when the operative note never says whether mesh went in.

This guide covers the 2026 rates, the modifiers that survive an audit, the bariatric bundling trap, and the ICD-10 pairings.

What CPT code 43281 covers, and what it excludes

The AMA CPT code set descriptor reads: Laparoscopy, surgical, repair of paraesophageal hernia, includes fundoplasty, when performed; without implantation of mesh. Two phrases in there do the heaviest lifting.

“Includes fundoplasty, when performed” means the wrap is part of 43281 whenever the surgeon does it in the same session. You cannot bill it separately. “Without implantation of mesh” is the selector between two codes. If mesh went in, 43281 is wrong and 43282 is right.

The code sits in the Laparoscopic Procedures on the Esophagus subsection of the CPT surgery codes. It applies whether or not a fundoplasty happened, as long as no prosthetic mesh reinforced the hiatal repair.

Mesh status is all that separates 43281 from 43282

Mesh implantation is the only clinical variable between the two codes. Both cover laparoscopic paraesophageal hernia repair with an optional fundoplasty. Make the call from the operative report, never from the surgical schedule.

Surgeons change their minds in the room. A planned mesh repair becomes a primary suture repair once the hiatus looks better than the imaging suggested, and the reverse happens too. Only the operative report settles the final code.

What Medicare pays for CPT 43281 in 2026

The 2026 national Medicare payment for CPT 43281 is about $1,425, in a facility or an office. Rates move with your locality. Check the exact figure in the CMS Physician Fee Schedule lookup tool for your MAC jurisdiction before quoting a patient.

Geographic practice cost indices, known as GPCIs, adjust each RVU component by payment locality under the CMS Physician Fee Schedule.

A practice billing in Manhattan collects a different amount than one billing the same code in rural Arkansas. The conversion factor also changes every January, so a rate you saved last year is already stale.

Where the $1,425 payment comes from

Medicare builds the payment from three RVU components, then multiplies the total by one conversion factor. For 2026 that factor is $33.4009 for clinicians outside the qualifying APM track, and $33.5675 for those inside it.

Knowing the split matters when you negotiate a commercial contract off a Medicare multiple.

Verify the values against the CMS relative value files before you use them in a contract negotiation. The numbers above are national values, not billing documentation.

Which modifiers hold up on a 43281 claim

A handful of modifiers come up regularly on 43281, and each one needs its justification written into the operative note. Applying the wrong modifier, or omitting a required one, delays payment and invites an audit.

Modifier 22 is the one payers audit hardest. The note has to describe what made the case harder than average, such as dense adhesions, prior abdominal surgery, or atypical anatomy.

Without that detail, expect a reduced payment or a refund request months later.

Where payers push back on CPT 43281

Medical necessity carries the claim. Medicare and most commercial payers want documentation that the hernia was symptomatic, and that a laparoscopic approach suited the case.

Payers look for dysphagia, regurgitation, respiratory symptoms, or GERD that medication did not control.

Elective repair of an asymptomatic paraesophageal hernia is not universally covered, and some payers require prior authorization before the case is booked.

Billing 43281 with bariatric surgery is the denial to plan for

The riskiest 43281 scenario is a concurrent bariatric procedure. EmblemHealth and several Blues plans deny 43281 when it appears on the same operative session as sleeve gastrectomy (43775) or Roux-en-Y gastric bypass (43644).

Their reasoning is that the hernia repair is integral to finishing the bariatric procedure safely.

• 43281 with 43775, sleeve gastrectomy: High denial risk. Payers treat hiatal repair as routine sleeve preparation. Separate billing needs an operative report showing substantial extra work beyond the gastric procedure.
• 43281 with 43644, gastric bypass: Moderate to high denial risk, on the same reasoning. NCCI edits change quarterly, so check the current pair status before you file.
• Modifier 59 is not a general workaround: EmblemHealth’s own policy states that modifier 59 will not override this bundling denial. Other payers set their own rules, so confirm each policy rather than appending 59 by habit.
• Appeal package: A successful appeal usually carries the operative report, a letter of medical necessity from the surgeon, and the payer’s own policy language.

Catching the combination before you file saves the 45 to 90 day appeal cycle. That is the whole point of denial management in a surgical practice, and it costs one check at the point of coding.

How a 43281 claim moves from the OR to payment

A 43281 claim passes through four hands before payment lands. Three of those handoffs are where it stalls, and each one stalls for a different reason.

1. The surgeon dictates. Mesh status, hernia type, sac reduction, and the wrap all live in that dictation. A detail left out here gets chased later, usually by phone.
2. The coder reads the note. Mesh status picks 43281 or 43282. A note that never mentions mesh means a call to the OR, and the claim waits in a queue.
3. The biller builds the claim. The diagnosis goes on, the NCCI pair gets checked if a gastric code is present, and the claim files electronically.
4. The payer adjudicates. Bundling edits and medical necessity edits fire at this point. A denial here costs 45 to 90 days to reverse.

Four mistakes that stall a 43281 claim

1. Coding from the scheduled procedure instead of the operative note.
2. Filing 43281 with a bariatric code without checking the current NCCI pair.
3. Leading with a symptom code such as R13.10 when K44.9 belongs first.
4. Appending modifier 22 with no complexity detail anywhere in the note.

Related codes in the paraesophageal hernia family

Coding 43281 correctly means knowing its neighbors. Each code below covers a distinct clinical scenario, and reaching for the wrong one creates audit exposure.

CPT 43280 is the code for an isolated laparoscopic fundoplication with no hernia repair. So a Nissen fundoplication for GERD in a patient with a sliding hiatal hernia is 43280, not 43281.

The hernia type and what the surgeon repaired drive the choice, not the presence of a wrap.

The ICD-10 codes that support medical necessity

Diagnosis coding decides whether a correct procedure code gets paid. K44.9 is the usual principal diagnosis for elective paraesophageal hernia repair, with reflux and symptom codes in support.

Confirm each code is still valid in the CDC ICD-10-CM lookup tool before you submit.

List the GERD codes (K21.0, K21.9) as secondary when the note names reflux as part of the rationale, especially where a fundoplasty was performed.

K44.9 on its own is defensible, but it invites a medical necessity review at some payers. Our ICD-10-CM codes hub covers the diagnosis families that pair with other surgical procedures.

What the operative note has to say

The operative report is the audit defense for a 43281 claim. Incomplete documentation is the usual root cause when an audit finds an overpayment, so the note needs each element below.

• Confirmed paraesophageal hernia: The report must state that a paraesophageal hernia was found, meaning Type II, III, or IV, rather than a sliding hiatal hernia.
• Laparoscopic approach confirmed: Document port placement and confirm the whole repair stayed laparoscopic. A conversion to open moves the case to a different code set.
• Hernia sac reduction: Most of these repairs reduce the sac from the mediastinum. Documenting that step supports the complexity of the procedure.
• Crural repair technique: Say how the hiatal defect was closed, including suture technique and the approximate size of the defect.
• Fundoplasty details, if performed: Name the wrap. Nissen is 360 degrees, Toupet is a partial posterior wrap, and Dor is anterior. Add the wrap length and any calibration method.
• Mesh absence confirmed: State “no mesh was placed” or “no prosthetic reinforcement was used.” That one phrase is the difference between 43281 and 43282.
• Blood loss and operative time: Required on any surgical claim, and the foundation for modifier 22 if the case ran long.

Before you submit: The five-line check

Run this check on every 43281 claim before it leaves the practice. It takes a minute and it removes the two denials this code attracts most.

• Does the note say paraesophageal hernia, rather than sliding hiatal hernia?
• Does it state that no mesh was placed?
• Does it confirm the whole repair stayed laparoscopic?
• Is K44.9 or K44.0 in the principal diagnosis position?
• If a gastric code shares the claim, has anyone checked the current NCCI pair?

How Pabau keeps surgical codes and operative notes together

Plenty of surgical practices run this workflow across three systems. The operative note lives in the EMR. Codes sit on a spreadsheet or in the coder’s head, and the claim lives in a separate billing tool. Every handoff is another chance for mesh status to go missing.

Practice management software like Pabau keeps them in one place. Treatment notes, procedure codes, and patient documents all sit on the same client record. Your coder reads what the surgeon wrote rather than a summary of it. Our claims management software then submits the claim through Claim.MD, our US clearinghouse partner, and tracks its status back to that record.

The outcome is a shorter loop. When a payer denies a 43281 claim, the denial lands next to the note and the code that produced it. Your biller can answer it the same day, instead of rebuilding the case from three systems.

Keep the code, the note, and the claim together

Pabau holds your operative notes, procedure codes, and claim status on one client record, and submits US claims through Claim.MD. See how surgical practices use it to cut rework on codes like 43281.

Conclusion

43281 is a well-paid code with one fragile dependency. The operative note either says mesh was not placed, or it doesn’t, and the rest of the claim follows from those few words. Fix the note template first, then worry about modifiers and NCCI pairs.

Move the check upstream, into the dictation itself, rather than catching it in the billing queue. That change costs one template field and saves a 90 day appeal.

Surgical billing gets easier when the code, the note, and the claim never leave the same record. Book a demo to see how Pabau handles 43281 claims from dictation through to payment.
