Medical Billing for Dermatology Practices

Dermatology Billing That Pays What You Earn

Dermatology billing involves high procedure volume, complex pathology coordination, and significant cosmetic vs. medical billing distinctions. Shave excisions, biopsies, Mohs surgery, and photodynamic therapy all carry precise coding rules. Payers aggressively audit dermatology for cosmetic vs. reconstructive distinctions, upcoded destruction codes, and unbundling violations. 360Solutions provides dermatology-specialised coders who capture every stage of Mohs, every biopsy site, and every cosmetic-medical split accurately.

Where Dermatology Practices Lose Revenue

These are the coding and billing pitfalls that cost dermatology practices the most — and where our specialised billers add the most value.

Mohs Surgery Stage Billing

Mohs micrographic surgery codes (17311–17315) are billed per stage and per specimen. Missing a stage, miscounting tissue blocks, or failing to document the surgeon as both surgeon and pathologist results in significant underpayment.

Cosmetic vs. Medical Distinction

Payers deny procedures coded as medical when documentation suggests cosmetic intent. Lesion removals, skin tag excisions, and laser treatments require clear medical necessity language. We audit documentation before submission.

Biopsy Site Counting

Multiple biopsy codes (11102–11107) allow billing for additional sites with add-on codes. Practices routinely undercode by failing to bill all separate sites or by using the wrong biopsy technique code (shave vs. punch vs. incisional).

Pathology Coordination

Dermatology-generated pathology specimens billed under the same group practice require careful coordination of professional and technical components. We prevent double-billing issues and ensure both components are captured correctly.

Denial Intelligence

Common Denial Patterns

Knowing these before submission is the difference between a 60% and a 96% first-pass rate.

Mohs stage count in claim exceeds documented pathology block count

Lesion destruction coded as medical without medical necessity diagnosis

Multiple biopsy sites billed without using add-on codes correctly

Cosmetic procedure billed with ICD-10 code inconsistent with medical necessity

E&M billed same day as procedure without modifier -25

Dermatology Billing FAQ

Questions From Dermatology Practices

We verify the surgeon-pathologist documentation, count stages and tissue blocks from the pathology report, apply the correct Mohs codes per stage, and coordinate with any secondary reconstructive procedure codes performed during the same session.

PDT codes (96567/96570/96571) require documentation of photosensitizer application and light activation. We verify time documentation, field size, and lesion count to select the correct code and prevent the most common PDT denials.
Yes. Biologic prior auth for atopic dermatitis and psoriasis requires step therapy documentation showing conventional treatment failure. We manage the full auth process including appeals when payers deny initial requests.
