CPT code 67840: Eyelid lesion excision billing guide

Key takeaways

CPT code 67840 covers excision of an eyelid lesion (excluding chalazion) without closure or with simple direct closure, and does not involve the lid margin.

Report 67840 once per eye, however many lesions you remove from that eyelid.

67840 sits under Surgery/Eye and Ocular Adnexa, so it is ophthalmology-specific. Choose 11440 instead when you excise a benign lesion by size from a broader facial site.

Modifiers E1-E4, RT/LT, and 50 all apply to 67840. Using the wrong one or omitting laterality is a top denial trigger.

Practice management software like Pabau pre-maps ICD-10 codes to CPT codes and scrubs claims before submission, which cuts 67840 denials.

CPT code 67840 covers excision of a lesion of the eyelid without closure or with simple direct closure. That descriptor comes from the American Medical Association (AMA). Two exclusions define its boundaries. The procedure must not involve the lid margin, and chalazion removals belong to their own code family, 67800-67808.

This code sits under the CPT classification Surgery/Eye and Ocular Adnexa/Eyelid/Excision, Destruction. Unlike the 11440 series, 67840 is anatomically specific to the eyelid as an ocular adnexa structure, not a general facial skin site.

The procedure itself is usually a sharp excision of a benign or suspicious eyelid skin lesion. That is followed by either no formal closure or simple layered closure. If reconstruction beyond simple closure is required, a separate reconstructive code applies. Document the closure type explicitly in the operative note, because missing that detail is a common audit trigger.

Key components of the 67840 descriptor

• Location: Eyelid only, not involving the lid margin
• Procedure type: Excision (not shave, not destruction)
• Closure: None or simple direct closure
• Units: One per eye, however many lesions are removed
• Exclusion: Chalazion removals are not billable under this code
• Classification: Surgery/Eye and Ocular Adnexa (not Integumentary System)

CPT 67840 vs CPT 11440: Choosing the right code

Both codes can apply to lesion removal from the eyelid, but they operate under different logic. CPT 67840 is procedure-specific and location-specific, keyed to the eyelid as an ocular structure.

CPT 11440 (and the 11441-11446 series) applies to benign lesion excision on the face, ears, eyelids, nose, lips, or mucous membranes. It is size-based rather than location-specific.

Three factors decide which code you report:

• Who performs the procedure, and under which specialty’s code family
• What the lesion’s characteristics are, including size and appearance
• What the clinical context is, whether ocular adnexa surgery or a skin visit

The American Academy of Ophthalmology (AAO) reinforces this distinction. If an ophthalmologist excises an eyelid lesion as part of ocular adnexa surgery, 67840 is the correct code regardless of lesion size.

If a dermatologist removes the same lesion during a skin procedure visit and bills by size, 11440 applies. When both specialties are involved in the same surgical episode, only one physician bills one code for that excision.

Applicable modifiers for CPT 67840

Modifier selection for 67840 is more complex than for most minor procedure codes. The eyelid has four distinct anatomical positions, and a procedure can involve one or both eyes. According to AAPC’s CPT code guidance, the following modifiers all apply to 67840 in specific circumstances.

Medicare generally requires the E-code modifiers (E1-E4) for eyelid-specific procedures. Some commercial payers prefer RT/LT instead, so verify the payer’s claims processing rules before you submit.

Payers also split on how they want a bilateral claim formatted. Billing modifier 50 without checking whether the payer wants one line or two separate line items is a frequent bilateral denial trigger. The map below pairs each eyelid position with its modifier and its matching ICD-10 code.

ICD-10 codes that support medical necessity for 67840

Pairing CPT code 67840 with the correct ICD-10-CM diagnosis code is what establishes medical necessity for payer review. Payers read the ICD-10 code to confirm the excision was clinically warranted rather than cosmetic. The link between diagnosis and procedure has to be explicit on the claim.

According to the CMS Physician Fee Schedule, cosmetic eyelid procedures are excluded from Medicare coverage. That makes the ICD-10 pairing a make-or-break element of every 67840 claim. You can also check pairings against CrossCoder’s CPT-to-ICD-10 crosswalk tool before submission.

The ICD-10 code you select must align with the clinical documentation. List D23.10 on a claim while the operative note describes a lesion at the lid margin, and the claim gets a medical necessity denial. 67840 explicitly excludes lid margin involvement.

An accurate diagnosis pairing anchors the entire claim. Always code to the highest level of specificity available, which means the laterality sub-codes (D23.111, D23.112, D23.121, D23.122) rather than the unspecified D23.10. Our ICD-10-CM code library lists the eyelid subcategories in full.

Medicare reimbursement and fee schedule for CPT 67840

Medicare reimbursement for CPT code 67840 varies by geographic location and place of service. FastRVU’s 2026 figures put the national non-facility rate at $277.90 and the facility rate at $134.27.

Verify the figure for your locality through the CMS MPFS lookup tool, because geographic adjustment factors move the final payment. Rates change annually with each Medicare Physician Fee Schedule update.

Use the FastRVU 2026 RVU lookup tool to calculate the Work RVU, Practice Expense RVU, and Malpractice RVU values for 67840 in your area. These figures are specific to Medicare, and commercial payer contracts may set rates independently.

Documentation requirements for CPT 67840

A complete operative note carries every 67840 claim. Missing one required element can trigger a medical necessity denial or a post-payment audit. The elements below must appear explicitly in the record for each claim.

• Lesion location: Specifically identify which eyelid (upper/lower, right/left) and confirm the lesion did not involve the lid margin
• Lesion description: Size, morphology, clinical appearance, duration, and symptom history (growth, bleeding, visual obstruction)
• Medical necessity rationale: Why excision was indicated (functional impairment, suspected malignancy, recurrence, failed conservative treatment)
• Technique: Method of excision (sharp dissection, laser, or other) and confirmation of the ocular adnexa approach
• Closure type: Explicit documentation of no closure, or description of the simple direct closure technique used
• Pathology decision: Whether the specimen was sent for pathological analysis and why (or why not)
• Chalazion exclusion: Confirm the lesion was not a chalazion, and add a brief clarifying note if there is any clinical ambiguity

Local Coverage Determinations (LCDs) add payer-specific requirements on top of these baseline elements. They are issued by Medicare Administrative Contractors (MACs) such as Novitas, Palmetto GBA, and CGS. Always verify the applicable LCD for your region, since medical necessity criteria for eyelid procedures vary between MACs.

Pathology add-on codes: When to report CPT 88305

When excised eyelid tissue is sent for pathological examination, CPT 88305 may be reported separately. That code covers surgical pathology with gross and microscopic examination. It arises most commonly when the lesion looks atypical, when malignancy is suspected, or when the clinical history warrants tissue confirmation.

Under standard CMS billing rules, 88305 is separately reportable rather than bundled into 67840’s global surgical package. Payer bundling policies still vary, and some commercial plans bundle 88305 into minor eyelid procedure payments. Before billing 88305 alongside 67840, check the payer’s medical policy or submit a pre-claim inquiry.

The documentation must also support the pathology decision. The operative note should say why the specimen was sent rather than discarded, particularly when the clinical appearance suggested a benign process.

Billing bilateral eyelid lesion excisions

Bilateral eyelid lesion removal in a single surgical session adds modifier complexity. Payer rules differ on how to report two separate excisions, and the wrong format generates an automatic denial. The two common approaches are one line item with modifier 50, or two line items with eyelid-specific modifiers.

• Medicare approach: Bill 67840 on a single line with modifier 50. Medicare then applies the 150% payment rule, paying the full amount for the first side and 50% for the second.
• Some commercial payers: Require two separate lines, with 67840 plus E1 or E3 on line one and 67840 plus E2 or E4 on line two.
• Always document separately: Each lesion needs its own entry in the operative note, covering location, size, technique, and closure.
• Same-session excisions from different eyelids: Use the most specific eyelid modifier for each one. Do not default to modifier 50 when the payer’s LCD requires individual line items.

Bilateral eyelid lesion billing is among the highest-frequency denial scenarios in ophthalmology. Reviewing the denial management strategies that suit your payer mix before you file prevents most of these rejections.

Multiple lesions in the same eye

Report 67840 once per eye, however many lesions you remove. The AAO’s coding guidance is explicit on this point, so a second unit for a second lesion on the same lid is not billable.

Multiple chalazia are the exception, and they are not 67840 territory at all. Excision of multiple chalazia on the same lid is 67801, from the chalazion family the descriptor already excludes.

Common billing mistakes and how to avoid claim denials

Most 67840 denials trace back to a small set of recurring errors. Billing staff who know the patterns can structure documentation and claim submission to head them off before adjudication.

• Wrong code selection (67840 vs 11440): Billing 11440 when an ophthalmologist performed the procedure under the ocular adnexa classification, or the reverse. Fix: Confirm the performing specialty and the code family alignment before submission.
• Missing medical necessity: Submitting a claim without a diagnosis code that establishes a functional or oncological indication. Fix: Pair a specific ICD-10 eyelid code with 67840, and avoid unspecified codes when laterality sub-codes exist.
• Missing lid margin statement: Not documenting that the lesion stayed clear of the lid margin. Fix: Add one sentence in the operative note confirming the lid margin was not involved.
• Reporting a second unit for a second lesion: 67840 applies per eye. Fix: Report one unit however many lesions came out of that eye.
• Chalazion miscoding: Billing 67840 for a chalazion removal. Fix: Use 67800-67808 for chalazion excisions. The operative note should reflect the pre-excision clinical impression, since the pathology report only clarifies afterward.
• Incorrect modifier for bilateral billing: Using one modifier 50 line when the payer requires two separate line items, or the reverse. Fix: Verify payer-specific bilateral rules before filing.
• Unbundling 88305 incorrectly: Billing 88305 when the payer’s policy bundles pathology into the global surgical fee. Fix: Run a claim edit check or query the payer’s policy before adding 88305.

How practice management software simplifies CPT 67840 billing

The documentation and code-pairing requirements for 67840 create manual checkpoints on every claim. Billing staff verify the modifier, confirm the diagnosis pairing, and check the payer’s bilateral rule by hand, one claim at a time.

Pabau’s ophthalmology claims management software moves those checks into the workflow. It pre-maps ICD-10 diagnosis codes to procedure codes, flags a missing laterality modifier, and validates the claim electronically before it leaves the practice.

For a practice filing eyelid excision claims in volume, automated scrubbing catches the errors listed above before a payer sees them. Electronic remittance advice and denial reason codes return to the same record, so rework and appeals start where the claim was built.

Conclusion

67840 is a narrow code, and the narrowness is the whole difficulty. Get the pairings right and the claim usually pays first time. Miss one and it comes back for rework.

The trade-off worth remembering is between specificity and speed. Coding to D23.111 instead of D23.10 takes a few extra seconds at the desk. Those seconds separate a paid claim from a medical necessity review. The same goes for the one sentence confirming the lid margin was clear.

Pabau’s claim scrubbing and ICD-10-to-CPT linking take the manual checks off your billing staff for every 67840 claim. Book a demo to see how it works for ophthalmology and surgical eye care practices.
