CPT code 96574 describes combined removal of hyperkeratotic, precancerous skin lesions followed by photodynamic therapy (PDT) using a photosensitizing drug and a light source to destroy abnormal cells. The code is limited to one use per patient per day and applies to procedures performed by a physician or other qualified health care professional. Nationally, this code is relevant because PDT is an established, minimally invasive option for treating actinic keratoses and other superficial precancerous lesions, with implications for utilization, coverage policies, and outpatient procedural billing.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical intent and service setting, payer coverage considerations, common modifiers used in billing, and where CPT 96574 fits within dermatologic procedural coding. The publication provides benchmarks and policy context relevant to both clinicians and revenue cycle professionals, including reporting constraints (one per day) and typical ambulatory settings where the service is delivered. Data not available in the input for specific associated taxonomies, ICD-10 diagnoses, and payer-specific reimbursement levels are noted where applicable.
