CPT code 67041 – Pars plana vitrectomy with epiretinal membrane removal

Key takeaways

CPT code 67041 covers pars plana vitrectomy with removal of a preretinal cellular membrane, such as an epiretinal membrane (ERM) or macular pucker.

Bill 67042 instead when the internal limiting membrane is peeled, and bill 67036 only when no membrane is removed.

The code carries a 90-day global period and pays about $955 nationally from Medicare in 2026, in facility and non-facility settings alike.

Vitrectomy codes bundle with each other on the same eye, so same-session endolaser is never billed on top of 67041.

Pabau’s claims management software validates each claim before it’s sent and submits CMS-1500 claims to thousands of US payers through Claim.MD.

CPT Code 67041: Official descriptor and procedure overview

CPT Code 67041 is the code for a mechanical pars plana vitrectomy with removal of a preretinal cellular membrane. The American Medical Association descriptor reads: Vitrectomy, mechanical, pars plana approach; with removal of preretinal cellular membrane (eg, macular pucker). Macular pucker is only an example. Any preretinal cellular membrane the surgeon identifies and peels as a distinct step qualifies.

The procedure has three documented steps: entry through the pars plana, mechanical removal of the vitreous, and identification and peeling of the preretinal membrane. All three must appear in the operative note before the claim goes out.

What CPT Code 67041 includes and what is excluded

CPT Code 67041 bundles three services into a single payment: the vitrectomy approach, vitreous removal, and peeling of one or more preretinal cellular membranes. Billing each component separately is unbundling under National Correct Coding Initiative (NCCI) edits and triggers denial or audit.

Two misunderstandings cause most of the incorrect claims on this code. First, some billers report 67036 (vitrectomy only) alongside 67041 on the same eye and date. They assume one code covers the vitreous work and the other covers the membrane. NCCI edits bundle 67036 into 67041 for the same eye in the same session.

Second, the internal limiting membrane (ILM) is a separate layer that 67041 does not describe. An ILM peel is billed as CPT 67042.

• Included in 67041: pars plana entry, vitreous removal, peeling of epiretinal membrane or other preretinal surface membrane
• Coded instead of 67041: an ILM peel, billed as 67042 whether or not the ERM is also peeled
• Bundled with 67041 on the same eye and date: 67036 (vitrectomy only), 67039 (focal endolaser) and 67040 (panretinal endolaser)

CPT 67041 vs. CPT 67042 vs. CPT 67036: Choosing the correct code

Code selection among 67036, 67041 and 67042 depends on which membrane the surgeon peeled and what the operative note documents. A vitrectomy with an epiretinal membrane peel is 67041. A vitrectomy with an ILM peel, with or without an ERM peel, is 67042. A vitrectomy with no membrane peel is 67036. Because these codes bundle with each other, the decision always ends on a single line.

Auditors also read the operative note for ILM staining, usually with indocyanine green or brilliant blue G dye. Staining suggests an ILM peel took place, even when the note never uses the phrase “ILM peel.”

Accepted ICD-10 diagnosis codes for CPT Code 67041

ICD-10 code H35.37- (puckering of macula, the code family for epiretinal membrane) is the primary diagnosis that establishes medical necessity for CPT Code 67041. The code needs a laterality character. An unspecified or mismatched eye is a direct denial trigger with Medicare and most commercial payers.

Medicare coverage for vitrectomy is set nationally, not by each Medicare Administrative Contractor (MAC). CMS national coverage determination (NCD) 80.11 applies in every jurisdiction and lists the covered ICD-10 codes. Commercial payers keep their own lists, so check the payer policy before pairing a less common secondary code.

Modifiers for CPT Code 67041

Laterality modifiers are required on every 67041 claim to Medicare and most commercial payers. A missing RT or LT is a common technical denial on ophthalmic surgical claims.

Modifier 59 rarely applies here. American Academy of Ophthalmology (AAO) guidance limits it to a fellow eye or a separate structure. It never covers a second vitrectomy code on the same eye and date.

Medicare reimbursement, RVUs, and global period for CPT Code 67041

The CMS Medicare Physician Fee Schedule (MPFS) assigns CPT Code 67041 a 90-day global surgical period. Routine post-operative visits in those 90 days are included in the base payment. Don’t bill them separately without the right modifier.

For 2026, 67041 carries 15.92 work RVUs and 28.59 total RVUs, identical in facility and non-facility settings. At the 2026 conversion factor of $33.4009, that works out to about $955 nationally.

Your own payment differs by locality because the MPFS applies Geographic Practice Cost Index (GPCI) adjustments. Use the FastRVU 2026 lookup tool to pull locality-adjusted figures for your MAC region.

Verify current-year figures in the MPFS, because rates change every January. Don’t use these national averages for accounts receivable benchmarking without a locality adjustment.

Prior authorization and documentation requirements for CPT 67041

Medicare fee-for-service does not currently require prior authorization for CPT Code 67041, but Medicare Advantage plans and most commercial payers do. Requirements vary by plan, so billing teams should verify authorization before every scheduled case. Practices with a medical billing compliance program usually build a pre-authorization checklist into surgical scheduling.

When prior authorization is required, payers generally ask for the following supporting documentation:

• Fundus photography or optical coherence tomography (OCT) imaging confirming the epiretinal membrane
• Best-corrected visual acuity measurements showing functional impairment (threshold varies by payer, commonly 20/40 or worse)
• Duration of symptoms and evidence of conservative observation (typically 3 to 6 months, payer-specific)
• Operative plan specifying pars plana approach and planned membrane peeling

The operative note behind a clean claim submission should document five elements:

• The pars plana entry site
• The instruments used to remove the vitreous
• The membrane identified, whether ERM, macular pucker or another preretinal membrane
• The technique used to elevate and peel it
• The laterality

Reviewers flag a note that skips any of these during claims audits.

Common denial reasons for CPT Code 67041 and how to avoid them

CPT Code 67041 denials cluster around five root causes. Each has its own resolution path, and naming the right one is the first step in a working denial management process.

Track denials by code, modifier and payer over rolling 90-day windows. Matching them against common denial codes shows which denial type dominates in your practice, so you fix that workflow first.

Billing CPT Code 67041 with companion and add-on codes

Few codes are reportable alongside CPT Code 67041 on the same eye, because the vitrectomy family bundles under NCCI edits. When several vitrectomy codes describe one session, report the one with the highest RVU value. A structured superbill documentation process makes sure each separately billable element still reaches the claim.

How claims management software reduces denials for CPT Code 67041

The five denial causes above share one trait. Each one is visible before the claim leaves the practice, if someone checks the claim against the operative note and the payer’s rules.

Pabau’s medical claims management runs validation checks every time you send a claim, so missing membership numbers or authorization codes surface first. Through the Claim.MD integration, Pabau submits electronic CMS-1500 claims to thousands of US payers. It also runs real-time eligibility verification before the surgery date.

Claim statuses update from the payer, and electronic remittance advice posts back against the claim it settles. Your team sees a 67041 denial as soon as the payer returns it, instead of weeks later on an aging report.

Pabau validates each claim before it’s sent and submits CMS-1500 claims to thousands of US payers through Claim.MD. Fewer retinal surgery claims come back denied.

Conclusion

CPT Code 67041 gets paid when the operative note proves the membrane peel and the claim matches it. Read the note before you choose between 67036, 67041 and 67042, and let the documented layer decide.

The trade-off is front-loaded work. An authorization check, a laterality match and a bundling review take minutes before submission. Each one skipped turns into a resubmission or an appeal, and the payment waits.
