Summary & Overview
CPT 11105: Punch Biopsy of Skin for Additional Lesions
CPT code 11105 represents the punch biopsy of skin for each separate or additional lesion, a procedure widely utilized in dermatology and integumentary surgery to diagnose skin disorders and neoplasms. This code is essential for clinicians seeking to obtain tissue samples for histopathological analysis, which informs patient management and treatment decisions. The procedure is typically performed in office or hospital outpatient settings, reflecting its accessibility and routine use in clinical practice.
Major national payers, including Aetna, Blue Cross Blue Shield, Cigna Health, Medicare, and UnitedHealthcare, provide coverage for services billed under CPT code 11105. Understanding payer policies and coding requirements is crucial for accurate billing and reimbursement. Readers will gain insights into clinical benchmarks, policy updates, and the broader context of skin biopsy procedures, including how this code fits within dermatology workflows and its relationship to related CPT codes. The summary also highlights common modifiers and associated taxonomies relevant to billing and compliance.
This publication offers a comprehensive overview of CPT code 11105, equipping healthcare professionals, billing specialists, and policy analysts with the information needed to navigate coding, payer coverage, and clinical applications for punch biopsy procedures.
CPT Code Overview
CPT code 11105 is used to report a punch biopsy of the skin for each separate or additional lesion, including simple closure when performed. This procedure is commonly performed in dermatology and integumentary surgery settings to obtain tissue samples for diagnostic evaluation. Typical sites of service include the office (Place of Service 11) and hospital outpatient departments. The punch biopsy is a minimally invasive technique that allows clinicians to assess a variety of skin conditions and lesions, supporting accurate diagnosis and treatment planning.
Clinical & Coding Specifications
Clinical Context
A patient presents to a dermatology or primary care office with multiple suspicious skin lesions. The provider determines that a punch biopsy is necessary to obtain tissue samples for diagnostic evaluation. The initial lesion is biopsied using procedure code 11104, and for each additional lesion biopsied during the same encounter, code 11105 is reported. The workflow includes local anesthesia, obtaining a cylindrical sample of skin, and performing a simple closure if needed. The tissue samples are sent to pathology for further analysis. This procedure is commonly performed in the office setting (Place of Service 11) or hospital outpatient department.
