CPT Code 11444: Benign lesion excision billing guide

Key Takeaways

CPT Code 11444 describes excision of a benign skin lesion from the face, ears, eyelids, nose, lips, or mucous membrane with an excised diameter of 3.1 to 4.0 cm, including margins.

Excised diameter equals the lesion’s greatest clinical diameter plus twice the narrowest margin needed for complete excision, measured and documented by the surgeon before excision. Coding from the post-excision specimen or pathology report, which shrink after skin tension releases and formalin fixation, is the most common cause of undercoding in the 114xx family.

Medicare covers CPT 11444 when medical necessity is documented per the applicable Local Coverage Determination (LCD); facility and non-facility reimbursement rates differ.

CPT Code 11444 covers excision of a benign skin lesion, including margins, from the face, ears, eyelids, nose, lips, or mucous membrane, with a final excised diameter of 3.1 to 4.0 cm. Claims for this code are denied more often than for most other integumentary procedures, and the reason is rarely the procedure itself.

The usual cause is a documentation problem: a missing pre-excision measurement, an excised diameter calculated from the shrunken post-excision specimen instead of the surgeon’s pre-excision clinical measurement, or a modifier applied without a supporting operative note.

CPT Code 11444: Official description and clinical context

According to the American Medical Association (AMA), which maintains the CPT code set, CPT Code 11444 reads: Excision, other benign lesion including margins, except skin tag (unless listed elsewhere), face, ears, eyelids, nose, lips, mucous membrane; excised diameter 3.1 to 4.0 cm.

Three elements determine whether this code applies. First, the lesion must be benign. Second, the anatomical site must fall within the listed locations: face, ears, eyelids, nose, lips, or mucous membrane. Third, the excised diameter must fall between 3.1 and 4.0 cm. All three conditions must be true.

The excised diameter is the lesion’s greatest clinical diameter plus the margin of normal tissue required on each side, measured and documented by the surgeon before the incision is made.

If the lesion sits on the scalp, trunk, or extremities, a different code family applies, and if the excised diameter is 2.1 to 3.0 cm, the correct code is CPT 11443 instead. For dermatology EMR software integrations, this distinction must be captured at the point of documentation, not reconstructed later.

The phrase “including margins” is clinically significant. It means the final diameter includes the margin of normal tissue removed around the lesion, not just the visible lesion boundary. Coders and clinicians must ensure the operative note records the lesion’s greatest clinical diameter and the margin width on each side before the incision is made.

This pre-excision clinical measurement is the only defensible basis for code selection, not the post-excision specimen or the pathology report. Once skin tension is released and the tissue is fixed in formalin, the specimen shrinks and no longer reflects the true excised diameter.

CPT Code 11444 fee schedule and reimbursement rates 2026

Medicare reimbursement for CPT 11444 varies by geographic payment locality and by place of service. The CMS Physician Fee Schedule lookup tool provides the authoritative, locality-specific dollar rates.

The table below compares how non-facility and facility rates relate to each other rather than listing exact dollar amounts, since those vary by Medicare Administrative Contractor (MAC) jurisdiction and change annually.

Because facility rates exclude practice expense costs, which the facility bears directly, physician reimbursement at a hospital outpatient department is lower than in an office setting.

For practices billing CPT Code 11444 mostly from an office location, the non-facility rate applies and yields a higher Medicare allowable. Verify the current locality-specific rate before submitting claims, since rates update annually.

RVU breakdown for CPT 11444

The Medicare payment amount is calculated by multiplying the total RVUs by the annual conversion factor and any geographic adjustment. Work, practice expense, and malpractice RVU values for CPT Code 11444 vary by locality and are published in CMS’s annual RVU files.

CPT 11444 Medicare reimbursement: Coverage and medical necessity

Medicare covers CPT Code 11444 when the procedure meets medical necessity criteria defined by the applicable Local Coverage Determination (LCD). For Novitas Solutions jurisdictions, the applicable policy is LCD L34938 (Removal of Benign Skin Lesions) together with its companion Billing and Coding Article A57113.

Other MACs maintain their own jurisdiction-specific LCD and Article pairs, for example LCD L35498 with Article A57482.

Not all benign lesion excisions qualify. Cosmetic removals of asymptomatic lesions with no functional impairment are generally excluded.

Medical necessity for CPT 11444 is typically supported when documentation establishes one or more of the following:

• The lesion causes pain, bleeding, or functional impairment.
• The lesion’s appearance raises concern for malignancy, requiring pathological confirmation.
• The lesion interferes with daily activities or the use of prosthetics.

The operative note must connect the clinical indication to the decision to excise. A note that records the procedure without a documented reason is the second most common cause of Medicare denial for this code.

Modifiers for CPT Code 11444

Modifier selection for CPT Code 11444 follows standard integumentary surgery rules. The table below covers the most commonly applied modifiers. Incorrect modifier use, particularly misapplying modifier -51 or -59, is a frequent audit flag for benign lesion excision claims.

Modifier -25 is particularly scrutinized for skin lesion excision claims. Payers require that the E&M note contain a separate, identifiable clinical decision-making process distinct from the surgical service. Simply including a pre-operative assessment in the operative note does not satisfy this requirement.

Documentation requirements for CPT Code 11444

A denied CPT 11444 claim almost always traces back to a specific documentation problem. Payers auditing benign lesion excision codes check for a consistent set of elements across the pre-operative assessment, operative note, and pathology report.

Using digital intake forms and structured operative templates helps practices capture all required data at the point of care, reducing the need for post-claim documentation requests. Good medical documentation workflows make this systematic rather than dependent on individual clinician habits.

• Lesion description: Document the lesion type (cyst, nevus, fibroma, etc.), anatomical location (e.g., right earlobe, left nasal ala), and clinical appearance in the pre-operative note or consultation record.
• Medical necessity statement: Explicitly document why excision is indicated. Link the clinical finding to the indication (symptom, functional impairment, or suspicion of malignancy).
• Pre-excision measurement: Record the lesion’s greatest clinical diameter before excision, in the pre-operative or operative note. This is the foundation of the excised diameter used for code selection and must be taken before the incision is made, not reconstructed afterward.
• Excised diameter: Calculate as the pre-excision lesion diameter plus twice the narrowest margin of normal tissue removed on each side. This pre-excision clinical measurement, not the post-excision specimen or pathology report, is what determines code selection for CPT 11444 (3.1 to 4.0 cm). Record the lesion size and margin width in the operative note before excising.
• Margin width: Document the margin of normal tissue planned and achieved. This supports the “including margins” language in the code descriptor.
• Operative note: Include anesthesia type, excision technique, wound closure method, and specimen submission details.
• Pathology report: Submit the lesion to pathology and attach the report. Medicare LCDs for benign lesion removal may require pathological confirmation of the benign diagnosis. Some MACs treat pathology submission as mandatory; verify your LCD.
• Post-operative note: Document wound status and any complications, particularly for larger excisions in cosmetically sensitive facial areas.

For mole mapping workflows, pre- and post-excision photographs can also support the clinical record, particularly when the lesion’s size or appearance justifies excision over observation.

ICD-10 codes used with CPT Code 11444

The ICD-10 diagnosis code must support medical necessity for the excision. The most commonly paired codes for CPT 11444 come from the benign neoplasm and skin cyst categories. Payers cross-reference the diagnosis code against their LCD-covered code list before adjudicating the claim.

Always verify the selected ICD-10 code appears on the covered diagnosis list for your payer’s applicable LCD. Using a code not included in the LCD policy requires a written medical necessity explanation or an advance beneficiary notice (ABN) for Medicare patients.

The ICD-10-CM code lookup from CMS is the primary reference for confirming code validity and effective dates.

Related CPT codes: The 114xx benign lesion excision family

CPT Code 11444 belongs to a family of codes covering benign lesion excision from the face, ears, eyelids, nose, lips, and mucous membrane. Code selection depends entirely on the excised diameter, measured and documented by the surgeon before excision as the lesion’s clinical diameter plus margins.

The AAPC Codify CPT lookup lists the full code hierarchy for this section. CPT 11441 covers the next lower diameter tier at the same anatomical sites, using the identical excised-diameter measurement rule.

CPT 11444 vs 11442 vs 11446: Choosing the correct code

The diameter thresholds are absolute. A pre-excision clinical measurement (lesion diameter plus margins) of 3.05 cm codes to 11443, not 11444, and a measurement of 4.1 cm codes to 11446. This pre-excision figure, documented by the surgeon before the incision is made, is the sole determinant of correct code selection, not the post-excision specimen or the pathology report.

The most common mis-coding pattern in this family is coding from the post-excision specimen or the pathology report instead of the pre-excision clinical measurement.

For example, a clinician documents a lesion measuring 3.5 cm and plans margins of 3 mm on each side: excised diameter = 3.5 cm + (2 x 0.3 cm) = 4.1 cm, which correctly bills as CPT 11446.

If the coder instead uses the fixed pathology specimen, which has shrunk to 3.6 cm or smaller after formalin fixation, the claim risks being undercoded to 11444.

The correct approach is to measure the lesion’s greatest clinical diameter and the planned margin width before excision, then calculate the excised diameter as lesion diameter plus twice the margin. Use that pre-excision figure, not the specimen or pathology measurement, as the basis for CPT code selection.

Coding guidelines and common billing errors for CPT Code 11444

Claim denials and audit findings for CPT Code 11444 follow predictable patterns. Most arise from three categories: wrong diameter measurement, missing medical necessity documentation, and incorrect modifier application. Reviewing these before submitting claims saves rework time and protects revenue.

• Measure before excision, not the specimen: The excised diameter is the lesion’s greatest clinical diameter plus twice the margin of normal tissue needed for complete excision, measured and documented by the surgeon before the incision is made. This rule applies to all codes in the 114xx family; the post-excision specimen and the pathology report are not valid substitutes, since both shrink after skin tension releases and after formalin fixation.
• Do not downcode based on the shrunken specimen: If the documented pre-excision clinical measurement (lesion diameter plus margins) was 3.5 cm, the correct code is 11444, even if the fixed pathology specimen later measures smaller. Code to the pre-excision clinical measurement, not the post-fixation specimen size.
• Report one code per lesion: Each lesion is coded separately using the appropriate size code. Do not combine two smaller lesions to justify a higher-diameter code.
• Bundling rules: CPT 11444 includes simple wound closure. If closure requires intermediate or complex repair (e.g., layered closure, flap, or graft), that repair code may be separately reportable. Check for bundling edits in your clearinghouse before submitting.
• Pathology is not always bundled: Sending the specimen to pathology (CPT 88305 or similar) is generally separately reportable and typically billed by the pathology provider. Confirm with the pathology group before billing.
• Cosmetic vs. medically necessary: Excision of a benign lesion for cosmetic reasons alone is not covered by Medicare or most commercial insurers. Document the clinical indication explicitly.

How practice management software supports billing CPT Code 11444

Skin clinics and dermatology practices billing CPT Code 11444 frequently face the same set of problems:

• Measurements captured inconsistently across providers.
• Modifier decisions made at checkout rather than during documentation.
• ICD-10 codes selected from memory rather than from LCD-verified lists.

Each of these problems is preventable with the right workflow infrastructure. Practices using claims management software built for clinical environments can configure structured fields that prompt clinicians to record pre-excision clinical measurements, select from pre-approved diagnosis code lists, and flag missing operative note elements before a claim is generated.

For skin clinic software integrations, this means the billing workflow begins at the clinical note, not at the front desk. When the excised diameter field is a required input in the procedure record, the code selection logic can be pre-configured to surface the correct code from the 114xx family based on that measurement.

Automated billing workflows can also route claims through a pre-submission scrub that checks for an ICD-10 code, a modifier justification note, and pathology submission confirmation before releasing the claim.

Practices such as London Face & Skin use this kind of scrub to keep facial excision claims moving without manual rework.

Practices working toward structured documentation can also reference broader practice management software capabilities to understand how claim scrubbing, modifier logic, and fee schedule maintenance integrate into a unified billing workflow.

Conclusion

CPT Code 11444 is straightforward in its descriptor but frequently misapplied in practice. The diameter threshold, 3.1 to 4.0 cm, calculated as the lesion’s clinical diameter plus margins and measured before excision, is the single most audited element. Coding from a shrunken post-excision specimen is the most common way practices undercode this procedure.

Pair a correctly documented pre-excision measurement with a clear medical necessity indication and the correct ICD-10 code, and most denial and undercoding risk is eliminated before the claim leaves the practice.

Pabau’s claims management software helps skin clinics build these checks directly into their documentation and billing workflows. To see how it works for benign lesion excision billing, book a demo.
