CPT Code 17280: Malignant Lesion Destruction

Key takeaways

CPT Code 17280 reports destruction of a malignant lesion on the face, ears, eyelids, nose, lips, or mucous membranes measuring 0.5 cm or less

Five accepted destruction methods: laser surgery, electrosurgery, cryosurgery, chemosurgery, and surgical curettement

Size documentation is the most common claim denial trigger: measure the lesion diameter including margins before selecting the code tier

Pabau’s claims management software links clinical documentation to the correct CPT code at the point of care, reducing transcription errors for size-tiered codes

CPT Code 17280 is the destruction of a malignant lesion on the face, ears, eyelids, nose, lips, or mucous membranes. The lesion diameter, including margins, must measure 0.5 cm or less. It sits at the smallest end of a six-tier size series tracked in CMS Physician Fee Schedule data.

This reference covers the full descriptor, accepted destruction methods, modifiers, Medicare reimbursement, RVU data, and the ICD-10 crosswalk. It also covers documentation requirements and the bundling rules around same-day biopsy and the global surgery period.

Dermatology practices billing skin lesion destruction codes regularly encounter claim denials tied to incomplete operative notes, incorrect size tier selection, and modifier misuse.

Skin clinic software like Pabau connects the clinical encounter directly to the claim. Its claims management software maps lesion size and location at the point of care, so the right code tier is captured before submission.

CPT Code 17280: Full descriptor and clinical overview

CPT Code 17280 describes the destruction of a malignant lesion located on the face, ears, eyelids, nose, lips, or mucous membranes. The lesion diameter, including margins, must measure 0.5 cm or less.

The code sits within the Integumentary System section of the AMA CPT code set. It falls under the subsection covering destruction of malignant lesions on facial and mucosal sites (17280-17286).

The lesion diameter must be measured with margins included. Anatomical site and size together determine which code in the series applies. Code selection cannot rely on clinical impression alone: the operative note must document both.

Accepted destruction methods for malignant lesion coding

The AMA descriptor uses “e.g.” to introduce the destruction methods, confirming the list is illustrative rather than exhaustive. Five modalities are explicitly named, and all are recognized by CMS under coverage article A57638 as appropriate for malignant lesion destruction.

• Laser surgery: ablative or non-ablative laser energy directed at the lesion tissue
• Electrosurgery: high-frequency electrical current used to destroy lesion cells
• Cryosurgery: application of liquid nitrogen or another cryogen to freeze and destroy tissue
• Chemosurgery (Mohs technique excluded): chemical agents used to destroy malignant tissue layer by layer. Mohs micrographic surgery is reported under a separate code series (17311-17315)
• Surgical curettement: mechanical scraping of the lesion using a curette, typically followed by electrodesiccation

The destruction method used must be documented in the operative note. Payers may request this detail during claims review, particularly when cryosurgery or chemosurgery is used on a high-risk facial site. Practices that track clinical documentation standards across their procedure forms are better positioned to support these claims.

CPT 17280 vs related codes in the malignant lesion series

The 17280-17286 series covers the same anatomical sites (face, ears, eyelids, nose, lips, mucous membranes) but tiers by lesion size. Select the code that matches the measured diameter including margins. Upcoding to a larger size tier is a documented OIG audit risk.

The companion series for trunk, arms, and legs (17260-17266) uses the same size breakpoints but covers different anatomical territory. Lesion site determines which series applies: a 0.5 cm malignant lesion on the nose is 17280; the same-sized lesion on the back is 17260.

Dermatology practices that see patients for full-body mole mapping and lesion surveillance frequently bill across both series in a single visit.

ICD-10 codes that support medical necessity for CPT Code 17280

CMS Local Coverage Article A57638 links malignant lesion destruction to specific ICD-10-CM diagnosis codes. The diagnosis code on the claim must be one that establishes medical necessity: a confirmed or suspected malignancy at the documented site.

Submitting a benign lesion diagnosis code alongside 17280 will trigger an automatic denial. Codes for the eyelid, ear, and face sites also need a final digit for laterality (right, left, or unspecified) to be billable.

Use CrossCoder’s CPT-to-ICD-10 crosswalk tool to verify which ICD-10-CM codes your MAC currently accepts alongside 17280.

Local Coverage Articles can vary by jurisdiction: the A57638 list is the national reference, but some MACs apply narrower criteria. Confirm the applicable local policy before submitting a claim with an unfamiliar diagnosis and site pairing.

Modifiers for CPT Code 17280

Modifier selection depends on whether multiple lesions were treated and whether the visit included an evaluation and management service. It also depends on whether the lesion was on a paired anatomical site. Incorrect modifier use is among the most common reasons 17280 claims are flagged during post-payment review.

Modifier -59 on a biopsy code billed the same day as 17280 is a high-audit-risk scenario. If a lesion biopsy and destruction occur during the same visit, many payers bundle the biopsy into the destruction fee. Appending -59 without clinical documentation that the biopsy was performed on a separate, distinct lesion at a distinct site is an NCCI compliance risk.

Review the NCCI Policy Manual for current edit pairs before billing both codes together.

Medicare reimbursement and fee schedule for CPT Code 17280

Medicare payments for CPT Code 17280 are set by the Physician Fee Schedule (PFS) and adjust annually. Rates differ based on the setting where the procedure is performed: a non-facility (office) setting reimburses higher because the practice absorbs overhead costs directly. Use the CMS PFS lookup tool to retrieve the current-year rates for your specific locality.

RVU breakdown for CPT 17280

Relative Value Units (RVUs) form the basis of Medicare payment calculation. The total RVU for a code is multiplied by the Conversion Factor (CF) and the Geographic Practice Cost Index (GPCI) for your locality. This produces the final payment amount.

Facility vs non-facility rates

Because the practice expense RVU differs by setting, the non-facility (office) payment is consistently higher for CPT Code 17280 than the facility rate. When a dermatologist performs the destruction in their own office, they receive the higher non-facility amount.

When performed in a hospital outpatient department or ambulatory surgery center, the facility bills its own technical component. The physician then receives only the lower facility professional rate. Most dermatology practices performing 17280 do so in the office setting and receive the non-facility rate.

Documentation requirements for CPT Code 17280

CMS Local Coverage Article A57638 specifies what the medical record must contain to support a 17280 claim. Missing any of these elements is enough for a MAC to deny or recoup payment. Dermatology practices should build these requirements into their operative note templates before the encounter, not after.

• Lesion size with margins: the measured diameter in centimeters, explicitly including margins, recorded in the operative note
• Anatomical site: specific location within the covered sites (e.g., left lower eyelid, right nasal ala, upper lip vermillion border)
• Destruction method: which modality was used (cryosurgery, electrosurgery, laser, etc.) and any relevant parameters
• Diagnosis confirming malignancy: biopsy-confirmed pathology report or documented clinical justification for malignant diagnosis; the ICD-10 code must match a covered diagnosis
• Medical necessity statement: clinical rationale for destruction as the chosen treatment modality. This matters most if the approach is non-standard or the lesion sits in a functionally sensitive area, such as the eyelid or lip
• Pre-operative photographs: not universally required, but strongly recommended for periorbital and mucosal lesions where size and site verification may be disputed

Practices managing ongoing dermatology caseloads can standardize these documentation elements using digital clinical forms. These forms prompt the clinician to capture each required data point at the point of care.

Structured note templates reduce the risk of missing a size measurement or site descriptor in the operative record. The Pabau dermatology EMR supports customizable procedure templates aligned to CPT-tiered documentation needs.

Global surgery period and bundling rules

CPT Code 17280 carries a 10-day global surgery period under CMS. This means that follow-up visits related to normal post-operative recovery are bundled into the procedure fee for the 10 days following the date of service. Billing a routine post-op visit within that window using an E&M code will be denied by default.

An exception applies only when a separate, distinct problem unrelated to the destruction is documented and modifier -24 is appended.

NCCI bundling edits restrict billing 17280 alongside biopsy codes when the biopsy and destruction are performed on the same lesion during the same session. Current biopsy codes include 11102 and 11103 for a tangential biopsy, and 11104 and 11105 for a punch biopsy.

Incisional biopsy uses 11106 and 11107. Biopsy-then-destruction on a confirmed malignancy is the most common scenario where practices attempt to bill both codes. Verify current NCCI edit tables before billing any combination: the AAPC Codify platform includes NCCI edit pair lookup alongside the code descriptor.

Practices that monitor compliance across dermatology services benefit from resources like clinical compliance checklists adapted for skin procedure documentation.

Common billing errors and how to avoid them

No competitor reference currently provides a consolidated compliance error checklist for CPT Code 17280. These are the patterns that most commonly result in denials, downcodes, or post-payment audits for facial malignant lesion destruction.

• Measuring the lesion without margins: the code descriptor specifies diameter including margins. A lesion measured at 0.5 cm without margins may actually place on 17281 territory when margins are added. Measure correctly the first time or face a post-audit downcode
• Using 17280 for benign lesions: the 17280 series is for malignant lesions only. Benign facial lesion destruction belongs to the 17110-17111 series. Coding a benign lesion under 17280 is a misrepresentation regardless of anatomical site
• Billing same-day biopsy and destruction without modifier justification: most payers bundle the biopsy into the destruction fee when both happen at the same visit. This applies to a confirmed malignancy. Separate billing needs modifier -59, with documentation showing genuinely distinct lesions at distinct sites
• Omitting the destruction method from the operative note: “lesion destroyed” without specifying the method is insufficient. The operative note must name the modality, even if it seems self-evident to the clinician
• Billing 17280 without a confirmed malignancy diagnosis code: the ICD-10-CM diagnosis must support malignancy. Submitting with a “rule out” or benign lesion code will trigger a denial
• Ignoring the 10-day global period: billing a routine post-op wound check as an E&M needs modifier -24 documentation, or the claim will be denied

Practices with active dermatology billing workflows can build pre-submission claim scrubbers into their practice management system. These scrubbers flag denial-prone scenarios before the claim leaves the office. Tracking denial patterns by CPT code helps identify whether a specific error is systemic.

Compliance frameworks for aesthetic and medical practices provide a broader operational context for building these internal controls. Reviewing billing accuracy protocols alongside broader risk-reduction practices is worth doing as a combined audit exercise.

How Pabau supports dermatology billing for CPT Code 17280

Dermatology practices billing size-tiered codes like 17280 face a specific documentation challenge. The correct CPT code depends on a measurement captured during the procedure. By the time the claim is built, the clinician has moved on to the next patient. When that measurement lives in a paper note or a separate EHR field, transcription errors compound.

Pabau connects clinical documentation directly to the billing workflow. Lesion size, site, destruction method, and diagnosis can be captured in a structured procedure template at the point of care. The correct CPT code tier then surfaces automatically, based on the recorded measurement. Its claims management software carries those documented values through to the claim without a manual re-entry step.

Practices managing multi-site dermatology visits benefit from Pabau’s reporting layer. It can surface denial rates and claim volume by CPT code over time. That makes it easier to see whether 17280 claims fail at a higher rate than the rest of the dermatology billing mix.

For practices wanting to explore how this fits their workflow, understanding what a practice management platform covers is a useful starting point. From there, evaluating specific features becomes easier.

Conclusion

CPT Code 17280 leaves little room for error. A mismeasured lesion or an undocumented destruction method is enough to trigger a denial or a post-audit downcode. The practices that avoid this exposure treat lesion size, site, method, and diagnosis as data to capture at the point of care. They don’t leave these details to reconstruct later from memory.

The bundling rules around same-day biopsy and the 10-day global period cause most of the compliance exposure this code carries. Build both checks into your claim-scrubbing workflow before submission.
