Summary & Overview
CPT 11103: Tangential Skin Biopsy for Each Additional Lesion
CPT 11103 designates a tangential (shave or curette-type) biopsy performed on each additional separate skin lesion. Nationally, this code is central to outpatient dermatologic practice for diagnosing benign and other superficial skin lesions without full-thickness excision. Its proper use affects billing accuracy, coding compliance, and documentation of lesion-specific services.
The analysis covers major national payers: Aetna; Blue Cross Blue Shield plans; Cigna Health; Medicare; and UnitedHealthcare. Readers will find a concise overview of clinical context for tangential biopsies, comparisons to single-lesion coding, and guidance on documentation elements that typically support use of an additional-lesion code. The content also highlights common procedural settings and the procedural relationship to other dermatologic excisions.
This publication provides benchmarks and policy context relevant to coding and billing teams, practice administrators, and clinicians involved in outpatient dermatologic procedures. It summarizes typical sites of service, clinical scenarios where tangential biopsies are used, and the distinctions between single-lesion and multiple-lesion coding for accurate charge capture. Data not available in the input is noted where applicable.
CPT Code Overview
CPT 11103 describes a tangential biopsy of the skin (for example, shave, scoop, saucerize, curette) performed on each separate or additional lesion. This procedure is classified under Dermatology / Surgical procedures on the skin and typically occurs in an office setting (POS 11). The code covers surgical removal of superficial skin lesions using tangential techniques for diagnostic or therapeutic purposes.
Clinical & Coding Specifications
Clinical Context
A middle-aged patient presents to a dermatology clinic with one or more raised, well-circumscribed benign-appearing skin lesions on the forearm and lower leg. The clinician evaluates the lesions during an office visit (POS 11), documents lesion size, appearance, and location, and discusses options for diagnostic removal. A tangential (shave/scoop/saucerize/curette) biopsy is performed for each separate lesion to obtain tissue for histopathologic examination. The procedure is performed under local anesthesia with minor hemostasis as needed. Specimens are submitted to pathology with site-specific labels and accompanying clinical indications matching the recorded ICD-10 diagnosis codes.

Modifier
59(Distinct Procedural Service): Use when the tangential biopsy represented by11103is distinct or separate from other procedures performed at the same encounter and documentation supports separate anatomic sites or separate lesions beyond routine bundling rules. -
Modifier
51(Multiple Procedures): Use when multiple surgical procedures are performed during the same session; apply payer-specific rules for multiple procedure payment reductions when11103is reported in combination with other procedures. -
