CPT code 43282: Laparoscopic paraesophageal hernia repair with mesh

CPT code 43282 is the procedure code for laparoscopic surgical repair of a paraesophageal hernia with implantation of mesh, including fundoplasty when performed. Mesh is the only thing separating it from CPT 43281, which describes the same laparoscopic repair without mesh.

This reference covers the official descriptor, the modifiers that apply, and how Medicare pays the code by place of service. It also lists the ICD-10 codes that support medical necessity and the billing steps that keep the claim clean.

Key takeaways

CPT 43282 describes laparoscopic paraesophageal hernia repair with mesh. Use CPT 43281 when no mesh is placed.

Modifier -22 applies when the procedure is substantially more complex than typical. Document the added time and complexity in the operative note.

Medicare pays 43282 at different rates in facility and non-facility settings, and geographic adjusters apply on top.

ICD-10 codes K44.0, K44.1, and K44.9 are the primary medical necessity codes for this procedure.

Practice management software like Pabau flags ICD-10 mismatches and modifier issues before the claim reaches the clearinghouse.

CPT code 43282: Official description and clinical overview

CPT code 43282 describes laparoscopy, surgical, repair of paraesophageal hernia, includes fundoplasty, when performed; with implantation of mesh. The American Medical Association maintains this descriptor within the Digestive System surgery section of the CPT code set. It is a Category I code, so it represents a procedure that is widely performed and backed by substantial clinical evidence.

The surgeon accesses the abdominal cavity laparoscopically and reduces the herniated stomach or other viscera back through the diaphragmatic hiatus. Mesh is then secured over the hiatus to reinforce the repair and lower the recurrence risk. Fundoplasty wraps the gastric fundus around the lower esophagus to address reflux. It is included in the code when performed, but 43282 applies whether or not it was done.

When this code applies

Three conditions must all hold before 43282 applies. The approach is laparoscopic, the hernia is paraesophageal rather than a simple sliding hiatal hernia, and mesh is implanted during the same operative session. A conversion to open surgery moves the claim to a different code family, and a repair without mesh is 43281.

• Laparoscopic approach required — open repairs use separate codes in the 43332–43337 range
• Paraesophageal hernia only — sliding hiatal hernias have distinct coding pathways
• Mesh must be implanted — the operative note must document mesh type, size, and fixation method
• Fundoplasty is bundled when performed — do not separately report Nissen or partial fundoplication if done at the same session

When the operative note is ambiguous, work the three checks below in order and stop at the first one that fails.

CPT 43281 vs 43282: What separates the two codes

The only procedural difference between CPT 43281 and CPT 43282 is mesh. Both codes describe laparoscopic paraesophageal hernia repair. 43281 is reported when no mesh is implanted, and 43282 when mesh is. The common error is defaulting to 43281, which under-bills the procedure whenever the operative report documents mesh.

When reviewing the operative report, treat phrases such as “biosynthetic mesh,” “permanent polypropylene mesh,” or “biologic mesh secured with tacks” as the trigger for 43282. The AAPC’s CPT code lookup confirms mesh is the sole differentiator between the two codes.

CPT code 43282 modifiers: Which apply and when

Modifier selection for CPT 43282 depends on surgical complexity, setting, and whether additional procedures were performed. Incorrect modifier use is one of the top reasons this code is flagged in payer audits.

Modifier -22 is the most frequently misused. Payers want documentation that goes beyond checking a box. The operative note has to quantify the additional work, such as the time added, the extent of adhesions, or the prior repair anatomy encountered. Without that, the claim is reprocessed at standard rates or denied outright.

Medicare reimbursement rates for 43282 in 2026

Medicare pays CPT 43282 under the Medicare Physician Fee Schedule (MPFS), and the rate differs by place of service. The CMS Physician Fee Schedule lookup tool is the authoritative source for current national and locality-adjusted payment amounts.

Facility vs non-facility reimbursement for CPT 43282

The facility rate applies when the procedure is performed in a hospital or ambulatory surgery center (ASC). The non-facility rate applies in a physician office setting, though this repair is rarely performed outside a facility. The non-facility rate is typically higher, because it accounts for the practice expense of maintaining procedure-room equipment.

Exact dollar values vary by geographic payment locality and change with each annual CMS update. Verify current rates against the CMS fee schedule lookup rather than a third-party rate table, which may lag by a year. The FastRVU 2026 RVU lookup calculates work, practice expense, and malpractice RVU values with locality adjusters applied.

ICD-10 codes that support medical necessity for CPT 43282

Pairing CPT 43282 with the correct ICD-10-CM diagnosis code is what establishes medical necessity. A claim without a supporting diagnosis from the K44 diaphragmatic hernia category is denied or sent back for documentation. Check the pairing against your payer’s local coverage determination (LCD) first, since an LCD may restrict coverage to specific K44 subcategories.

K44.9 is the most common pairing for an elective laparoscopic paraesophageal hernia repair. K44.0 and K44.1 apply in acute or emergent settings where obstruction or vascular compromise is documented. K44 covers diaphragmatic hernias as a category, which is why paraesophageal hernias sit inside it. Pabau’s ICD-10-CM code library carries the wider K40–K46 hernia range, worth a look when the operative findings describe mixed hernia types.

Billing guidelines and coding tips for CPT 43282

A handful of billing patterns cause most denials on CPT 43282, and accurate documentation plus a pre-submission review prevents nearly all of them. A clean claim here means the right code, the correct modifier, a supporting ICD-10, and complete operative documentation before transmission.

• Document mesh explicitly — the operative note must name the mesh product, manufacturer, size, and fixation technique. Vague language such as “repair reinforced” will trigger a documentation request or a denial.
• Do not separately bill fundoplasty — CPT 43282 bundles the fundoplication. Billing 43280 or 43281 alongside 43282 for that component is denied as unbundling.
• Bill concomitant bariatric codes with caution — 43282 billed with sleeve gastrectomy (43775) or gastric bypass (43644) triggers denial reviews at several payers. EmblemHealth has documented a policy denying hernia repair codes billed concurrently with certain bariatric codes.
• Verify prior authorization early — payer policies on prior auth for 43282 vary. Some plans require authorization for the hernia repair separately from any concurrent bariatric procedure. Confirm the requirements before the procedure date, not after.
• Check NCCI edits — the National Correct Coding Initiative edits may bundle certain codes with 43282. Review the CMS NCCI tables and apply modifier -59 only where the procedures are genuinely distinct from the hernia repair.

Payer policy considerations and common denial reasons

Two payer policies come up repeatedly in the coding community around 43282. BridgeSpan Health publishes a reimbursement policy on hiatal hernia repair and gastropexy that sets out coverage criteria for mesh-reinforced repairs. EmblemHealth publishes a bariatric surgery denial policy that governs how hernia codes are processed alongside bariatric procedure codes. Read both provider policy libraries before submitting 43282 with any concurrent upper GI or bariatric code.

The denials that recur in practice trace back to four causes.

• Mesh documentation missing from the operative note
• Co-billing with a bundled procedure without modifier -59
• No supporting K44 ICD-10 code on the claim
• Prior authorization not obtained where the payer’s policy requires it

Routing 43282 denials by reason code shows a billing team which of the four causes is driving its rejections. That is what makes it possible to fix the cause instead of reworking each claim.

Related CPT codes to know alongside 43282

43282 sits within a family of laparoscopic upper GI procedure codes. Knowing how they relate helps a coder land on the right one when the operative findings are complex.

How billing software reduces CPT code 43282 claim errors

A code lookup ends at the descriptor. The claim still has to carry the right ICD-10 pairing, the correct modifier, and operative documentation that supports both. Practice management software like Pabau checks all three when the claim is created, rather than after the denial arrives.

Software that validates claims before submission does four jobs on a surgical claim like 43282.

• Automated NCCI edit checks before the claim is transmitted
• ICD-10 to CPT pairing validation that flags a missing or mismatched K44 code
• Modifier logic that surfaces the documentation modifier -22 requires
• Claim status tracking through the clearinghouse as the payer works it

Pabau integrates with the Claim.MD clearinghouse, processing claims across thousands of US payers and returning ERA data for payment reconciliation. A practice billing CPT 43282 can submit, track, and reconcile the claim in one place. That same system holds the patient record and the operative note the claim depends on.

Conclusion

CPT code 43282 pays or denies on the strength of one paragraph in the operative report. Mesh is what separates it from 43281, so the note has to name the product, its size, and how it was fixed.

Agree that standard with your surgeons before the next case, rather than reconstructing it during an appeal months later. Book a demo to see how Pabau checks a surgical claim’s codes, modifiers, and documentation before it goes out.
