Summary & Overview
CPT 96936: Reflectance Confocal Microscopy, Additional Lesion Interpretation
CPT code 96936 represents the provider interpretation and reporting of reflectance confocal microscopy for each additional skin lesion or area of diseased or damaged tissue. Reflectance confocal microscopy is a near–infrared, noninvasive imaging technique used to visualize skin architecture and identify abnormal lesions or scar formation. As dermatologic imaging expands, this code matters nationally for standardizing how additional lesion interpretations are billed and tracked across payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, common billing considerations, and the payer landscape that affects coverage and claim adjudication. The publication summarizes benchmarks and typical utilization patterns where available, highlights relevant policy updates affecting imaging interpretation billing, and clarifies coding intent and typical sites of service.
This summary equips billing managers, dermatology practice leaders, and policy analysts with a clear understanding of what CPT code 96936 denotes, why it is used, and what to expect in payer interactions and documentation requirements. Data not available in the input are noted where applicable in the full publication.
Billing Code Overview
CPT code 96936 describes reflectance confocal microscopy interpretation and reporting for each additional skin lesion or area of diseased or damaged tissue. The procedure focuses near–infrared light on the skin to detect abnormal lesions or scar formation; the light source is connected to a computer that displays the tissue image for interpretation. Use of this code indicates the provider interprets the imaging results and documents findings for an additional lesion or area beyond the primary site.
Service type: Diagnostic imaging interpretation and reporting
Typical site of service: Outpatient dermatology clinic or office-based skin imaging facility
Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with a history of multiple atypical nevi presents to a dermatology clinic for evaluation of several suspicious pigmented lesions identified on total body skin exam. The dermatologist performs in‑office reflectance confocal microscopy (RCM) to noninvasively visualize cellular architecture of individual lesions using near‑infrared light. The device captures real‑time images that the physician reviews and interprets immediately, documenting findings and recommendations for each lesion scanned. Typical workflow: triage and consent, targeted lesion selection after dermoscopic inspection, acquisition of RCM images per lesion, physician interpretation and documentation of each lesion’s RCM result, and determination of next steps (monitor, biopsy, or excision). Typical site of service: outpatient dermatology clinic or ambulatory surgical center equipped with RCM. Service type: diagnostic imaging/interpretation for each additional skin lesion evaluated using reflectance confocal microscopy.
