CPT code 58110 denotes an add-on procedure for endometrial biopsy performed during the same session as colposcopy. This code clarifies billing when a clinician obtains endometrial tissue while conducting a colposcopic exam, ensuring the procedure is reported distinctly from the primary colposcopy service. Nationally, proper use of this code affects claims accuracy, revenue capture for add-on services, and compliance with payer bundling rules.

This analysis covers major national payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of billing context, common modifiers and billing considerations, and how the code is typically used in outpatient gynecologic practice. The publication outlines benchmark expectations and typical payer coverage patterns where available, plus clinical context linking the add-on biopsy to colposcopy sessions.

The report is intended for billing managers, clinical coders, and policy analysts seeking practical guidance on reporting and documentation implications for CPT code 58110. Data not provided in the input (such as payer-specific policy language, ICD-10 pairings, and utilization benchmarks) is noted as unavailable where applicable in the fuller publication.
