CPT code 11312: Shaving of epidermal or dermal lesion, face

Key takeaways

CPT code 11312 covers shaving of a single epidermal or dermal lesion measuring 1.1 to 2.0 cm. The sites are the face, ears, eyelids, nose, lips, and mucous membrane.

Code selection across 11300-11313 turns on two documented variables only: the anatomic group and the lesion diameter measured before removal.

Shave removal codes take the lesion diameter alone. Unlike the excision codes, you never add surgical margins to reach the size tier.

In 2026 the code carries 1.27 work RVUs and 4.51 total non-facility RVUs, which is roughly $151 nationally before geographic adjustment.

Practice management software like Pabau keeps the site, the measurement, and the indication in one patient record. Your coder and any auditor then read the same note.

CPT code 11312 bills the shave removal of a single epidermal or dermal lesion on the face, sized 1.1 to 2.0 cm. Also, ears, eyelids, nose, lips, and mucous membrane fall in the same anatomic group.

The American Medical Association (AMA) owns the CPT code set, and it splits the shaving family into three anatomic series. In addition, two other series cover a lesion of the same size elsewhere on the body. As a result, picking the wrong series changes what the claim pays.

Below you get the official descriptor, the selection matrix for the whole family, and the 2026 RVUs and payment amounts. After that come modifiers, ICD-10 pairings, documentation requirements, and the errors that draw payer attention.

CPT code 11312: definition and clinical description

CPT code 11312 describes the shaving of a single epidermal or dermal lesion measuring 1.1 to 2.0 cm. Specifically, the listed sites are the face, ears, eyelids, nose, lips, and mucous membrane.

The code sits in the Integumentary System section of the CPT manual. More specifically, its subsection, Shaving of Epidermal or Dermal Lesions, runs from 11300 to 11313. Per the AMA CPT code set overview, shaving here means sharp removal with a blade or razor, without a full-thickness dermal excision.

The lesion comes off at or just below the plane of the surrounding skin. The base is left to heal by secondary intention, so no suture closure is involved.

Sending the specimen to pathology is optional and does not change the code. By contrast, intent does change it. If the clinician performed a tangential biopsy for diagnosis, the biopsy codes apply instead.

Two conditions must both be true before you can report 11312. The lesion has to sit in the facial anatomic group, and the measured diameter has to fall between 1.1 and 2.0 cm. In short, either one on its own is not enough.

How to choose between 11312 and the adjacent shave removal codes

The anatomic series and size tiers

The 11300-11313 family is three anatomic series of four size tiers each, and nothing else. Codes 11300-11303 cover the trunk, arms, and legs, while codes 11305-11308 cover the scalp, neck, hands, feet, and genitalia, and codes 11310-11313 cover the face, ears, eyelids, nose, lips, and mucous membrane.

Within each series the four tiers step up by size. They run 0.5 cm or less, 0.6 to 1.0 cm, 1.1 to 2.0 cm, then over 2.0 cm.

2026 RVU comparison by code

The matrix below carries the 2026 total non-facility RVU for each code, taken from the CMS Physician Fee Schedule relative value files. It shows what a wrong series costs you. For example, a 1.5 cm facial lesion billed as 11302 gives up 0.57 RVU against the correct 11312.

Measuring lesion diameter correctly

Measure before you remove, not after. Specimens contract once they are off the patient, and the pre-procedure diameter is the figure that sets the code. The CMS billing article A57113 states that the measurement is made prior to removal. Accordingly, practices using an integrated measurements tracking tool can capture it at the point of care.

One rule separates this family from the excision codes. Shave removal is sized on the lesion diameter alone. By contrast, excision codes are sized on the lesion plus the narrowest margin, doubled. As a result, adding margins to a shave measurement is a quiet way to overstate the tier.

Where 11312 stops: eyelid, lip, and mucous membrane boundaries

The facial series is the only one in this family that borders other CPT chapters. As a result, that is where most of its miscoding happens. Three boundaries are worth knowing before you report 11312.

Eyelids. Use 11310-11313 when the lesion involves mainly the skin of the eyelid. Once the removal takes in the lid margin, the tarsus, or the palpebral conjunctiva, the eyelid excision codes apply, and 67840 is the usual choice. In every case, the operative note has to say which structures came off. For example, a note that only says “eyelid lesion removed” cannot support either code.

Lips. A lesion on the skin of the lip stays in this family. In contrast, a lesion on the vermilion border or the mucosal surface is a different anatomic target, and it also takes a different ICD-10 code.

Mucous membrane. The descriptor does include mucous membrane, so an intraoral shave can be reported here. If the documentation instead describes excision of mucosa and submucosa of the vestibule of the mouth, the 40810-40812 family is the accurate one.

Shave removal vs. biopsy vs. excision: coding differences

Miscoding a shave removal as a biopsy or an excision is one of the steadier audit findings in dermatology. The three procedures differ by technique, depth, closure, and code family. A shave heals by secondary intention, so the graft site preparation codes, such as 15005, have no place here.

CMS article A57113 is explicit on the biopsy boundary. Do not report 11300-11313 when a tangential shave biopsy of the lesion was performed.

Destruction is a fourth pathway that gets folded in by mistake. Freezing or curetting a premalignant lesion such as an actinic keratosis is destruction, and it belongs to 17000-17004. Instead, that family is sized by lesion count, not by diameter. Likewise, skin tags are a separate carve-out, reported with 11200 and counted rather than measured.

For a benign facial lesion of the same 1.1 to 2.0 cm band that was excised rather than shaved, 11442 is the comparison code.

CPT 11312 RVU values for 2026

Relative value units are the basis of Medicare payment under the Physician Fee Schedule. Work RVU covers clinician time and skill. Practice expense RVU covers overhead, and it splits by setting because office overhead differs from hospital overhead. The malpractice RVU covers professional liability. The figures below come from the CMS RVU file for calendar year 2026.

The setting difference on this code is unusually wide. The non-facility total is two and a half times the facility total, because the office absorbs the supplies, the room, and the staff time. Still, verify the current year with the CMS Physician Fee Schedule search tool before you use these numbers in a compensation model.

Reimbursement rates for CPT code 11312

Medicare payment is the total RVU multiplied by the annual conversion factor, then adjusted for your locality. For 2026 there are two conversion factors. Specifically, qualifying alternative payment model participants are paid at $33.5675, and everyone else at $33.4009. In turn, the national amounts below apply the second figure and carry no geographic adjustment.

Your actual payment will differ. That is because geographic practice cost indices move each locality up or down, and commercial payers set their own multiples of the Medicare rate. Instead, treat these figures as the national baseline, not as a quote.

Medicare coverage and medical necessity

Medicare covers shave removal when medical necessity is documented, and not otherwise. CMS billing and coding article A57113, which supports local coverage determination L34938, sets out the requirements for removal of benign skin lesions.

Cosmetic removal of a lesion that causes no symptoms and no functional problem is not a covered service. In practice, that line gets tested more often on the face than anywhere else.

• The lesion must cause documented symptoms such as bleeding, itching, pain, or repeated irritation
• The clinical indication belongs in the physician note, not only in the diagnosis code
• For an elective cosmetic removal, the patient signs an Advance Beneficiary Notice before the service
• Local coverage determinations from your Medicare Administrative Contractor can add criteria, so check the one that applies to you

Bundling and NCCI edits for CPT 11312

CPT 11312 carries a multiple procedure indicator of 2, so the standard reduction applies. The highest valued procedure of the session pays in full, and each additional one pays at 50 percent. That reduction is expected and correct, so it is not a denial to appeal.

The code also has a 000-day global period. There is no postoperative window, which is why a separately identifiable visit on the same day can still be billed with modifier 25. In addition, the bilateral surgery indicator is 9, meaning the bilateral payment rule does not apply to this code at all.

Modifiers for CPT code 11312

Modifiers add context about how a procedure was performed without changing the code itself. In practice, which ones you need depends on the scenario and the payer. Medicare rules and commercial payer rules diverge here more than coders expect, so confirm before you submit.

ICD-10 codes commonly billed with CPT code 11312

Every CPT claim needs a diagnosis code that establishes medical necessity. In practice, on the face this is a specificity problem more than a selection problem. For example, several of the relevant codes are category headers rather than billable codes.

D23.3 is a header and will reject on its own. By contrast, the eyelid codes go six characters deep. The pairings below reflect the FY2026 ICD-10-CM code set.

Pick the code that matches the documented finding for that encounter. A generic code where a specific one exists is a standing audit flag, and on the eyelid it is also a straightforward denial.

Documentation requirements for CPT code 11312

Documentation decides whether an 11312 claim survives review. In other words, the procedure note has to let a reviewer who has never seen the patient confirm the code without asking a question.

Digital clinical forms help here, because they capture the required fields at the point of care instead of leaving them to be reconstructed afterward. For example, a note reading “lesion removed from face” supports nothing.

• Anatomic site: name the exact location, such as “left nasal ala” rather than “face”. It has to fall inside the 11310-11313 group.
• Lesion diameter: record the measurement in centimeters, taken before removal. State it plainly: “lesion measured 1.5 cm prior to removal”.
• Technique: state that the lesion was shaved with a blade or razor and that no full-thickness excision was performed.
• Clinical indication: say why the lesion was removed. Medicare needs bleeding, irritation, pain, or functional impairment, not a cosmetic preference.
• Eyelid detail: for an eyelid lesion, state whether the lid margin, tarsus, or palpebral conjunctiva was involved. In turn, that sentence decides between 11312 and 67840.
• Pathology disposition: note whether a specimen went to the laboratory. If none was sent, a one-line explanation is enough.
• Wound management: record whether the base was cauterized, treated with a hemostatic agent, or left to heal by secondary intention.

Common coding errors and how to avoid them

Errors in this family fall into four buckets: the wrong anatomic series, the wrong size tier, confusion with biopsy or excision, and unbundling. Each one maps to a documentation control that removes it. Once you build the control into the template, the error stops recurring.

• Reaching for 11306 or 11307 by habit: those codes cover the scalp, neck, hands, feet, and genitalia. For example, a 1.5 cm lesion on the cheek is 11312, and no reading of the descriptor makes 11306 correct.
• Billing 11312 for a trunk or limb lesion: a 1.5 cm lesion on the forearm is 11302. In short, the three anatomic series are mutually exclusive.
• Sliding one tier by size: a facial lesion measured at 0.9 cm is 11311, and one over 2.0 cm is 11313. Either way, billing a tier the measurement does not support is an error.
• Adding margins to the measurement: margins belong to the excision codes. A 0.9 cm facial lesion does not become 11312 because the clinician took a 0.3 cm margin.
• Coding a tangential biopsy as a shave removal: CMS article A57113 says not to report 11300-11313 when a shave biopsy was performed. Instead, diagnostic sampling belongs to 11102-11107.
• Missing the eyelid depth statement: in practice, without a line on what structures were removed, an eyelid claim can be denied whichever code you chose.
• Dropping modifier 25 on a same-day visit: as a result, a separately identifiable E/M without the modifier gets bundled into the procedure and is not paid.

How Pabau supports documentation for shave removal billing

Most 11312 problems start before anyone builds a claim. The clinician records the procedure in one place, and the coder works from a summary that has lost the measurement or blurred the exact site. Practice management software like Pabau keeps both in the same patient record, so the note your coder reads is the note the clinician wrote.

The practical fix is a procedure template that will not close with a required field empty. For example, Pabau’s skin clinic software lets you build a shave removal form with four required fields.

The form asks for the anatomic site, the pre-removal diameter in centimeters, the technique, and the indication. In turn, that turns the two variables 11312 depends on into a step nobody can skip.

Pabau’s role in a US practice is the record rather than the clearinghouse. Your biller or billing service submits to Medicare, and what Pabau gives them is a complete, timestamped chart to code from.

When a reviewer requests support for a claim, everything comes out of one system. The procedure note, the photographs, the diagnosis codes, and the audit trail sit together rather than in three places.

For dermatology EMR software users, that consistency is what shortens an audit response. The documentation baseline is built into every encounter rather than added afterward.

As a result, practices combining Pabau’s patient record management with its compliance management tools spend less administrative time on records requests.

Make the measurement part of the note, not an afterthought

Pabau keeps procedure notes, photographs, and lesion measurements in one patient record. Your coder never has to guess the site or the size behind a shave removal claim. Book a demo to see how dermatology practices set this up.

Conclusion

CPT code 11312 has two conditions and no others. Specifically, the lesion sits on the face, ears, eyelids, nose, lips, or mucous membrane, and it measures 1.1 to 2.0 cm before removal.

Almost every denial in this family traces back to a note that missed one of those two facts. Otherwise, the rest come from a coder defaulting to the scalp and neck series out of habit.

Measure first, name the exact site, describe the technique, and say why the lesion had to go. In addition, on the eyelid, add a line about which structures were removed.

Pabau builds those habits into the encounter itself, so the documentation is right before the claim is ever created. To see how that works in a dermatology setting, book a demo with the Pabau team.
