Summary & Overview
CPT 54105: Biopsy of Penis, Deep Skin Lesion
CPT code 54105 represents a diagnostic surgical procedure: a biopsy of the penis collecting deep skin lesion tissue for histopathologic evaluation. This code matters nationally because penile biopsies, while uncommon, are essential diagnostic steps for conditions ranging from inflammatory dermatoses to suspected malignancy; accurate coding ensures appropriate clinical documentation and claims processing across payers. Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will learn the clinical context for use of CPT code 54105, typical sites of service, and common documentation elements that support medical necessity. The publication summarizes payer coverage patterns and billing considerations, highlights national-level benchmarks where available, and outlines policy or coding updates that affect billing and reimbursement for penile biopsy procedures. When specific data points were not supplied in the input, the text notes that those data are not available. The goal is to give clinicians, billing professionals, and policy analysts a concise reference on the clinical purpose and billing context for CPT code 54105.

Clinical & Coding Specifications
Clinical Context
A male patient presents to a urology or dermatology clinic with a persistent, suspicious lesion of the penis (for example, a firm indurated nodule, ulcerated lesion, or atypical pigmented lesion) that requires histologic diagnosis. Typical presentation includes localized pain, bleeding, change in lesion appearance, failure to respond to topical therapy, or concern for malignancy such as squamous cell carcinoma or penile intraepithelial neoplasia. The provider obtains informed consent, examines the lesion, prepares the area with antiseptic and local anesthesia, and performs a deep incisional or punch biopsy of the penile dermis to obtain adequate tissue for pathologic evaluation. Specimens are handled per laboratory protocol (labeled, preserved in formalin, and submitted with relevant clinical history). The patient is given wound care instructions and arranged for pathology results and any required follow-up, such as further excision, staging, or oncology referral based on histopathology.
