CPT 11106: Incisional Biopsy of Skin with Simple Closure
CPT code 11106 is a nationally recognized billing code for the incisional biopsy of skin, including simple closure when performed. This surgical procedure is commonly used to diagnose skin lesions or abnormalities that require tissue sampling for further evaluation. The code is relevant across a wide range of clinical settings, particularly in office-based practices, and is covered by major payers including Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare.
This publication provides a comprehensive overview of CPT code 11106, detailing its clinical context, payer coverage, and associated benchmarks. Readers will gain insight into the procedural specifics, typical site of service, and the importance of accurate coding for reimbursement and compliance. The analysis also highlights relevant policy updates and trends affecting the use of this code, as well as its relationship to common modifiers and related codes. By understanding the nuances of CPT code 11106, healthcare professionals and billing specialists can stay informed about current practices and requirements for skin biopsy procedures.
CPT Code Overview
CPT code 11106 describes an incisional biopsy of skin, such as a wedge biopsy, including simple closure when performed. This procedure is classified under surgery and is typically conducted in an office setting (Place of Service 11). The incisional biopsy is used to obtain a sample of skin tissue for diagnostic purposes, often when a lesion or abnormality requires further evaluation. The inclusion of simple closure means that the wound is closed in a straightforward manner following the biopsy. This code is essential for clinicians who need to investigate skin conditions that cannot be diagnosed through less invasive methods.
Clinical & Coding Specifications
Clinical Context
A patient presents to the office with a suspicious skin lesion, such as a nodule or plaque, that may represent a neoplasm or other abnormality. The provider determines that an incisional biopsy is necessary to obtain a tissue sample for diagnostic purposes. Using a wedge technique, the provider removes a portion of the lesion, including some normal tissue, and performs a simple closure of the biopsy site. The procedure is typically performed in an office setting and is used to evaluate lesions with uncertain behavior, possible malignancy, or other skin disorders.

11107: Each separate or additional lesion (list separately in addition to code for primary procedure)
11107 is used in conjunction with 11106 when the provider performs incisional biopsies on more than one lesion during the same session. The primary procedure is coded with 11106, and each additional lesion is reported with 11107. These codes are commonly used together when multiple biopsies are required for diagnostic evaluation.
