CPT code 19001 is an add-on CPT code for puncture aspiration of each additional cyst after the first. It identifies incremental work when multiple cysts are treated in the same encounter and matters for accurate procedural reporting and payment. As an add-on, 19001 is reported in conjunction with the primary aspirational cyst procedure to reflect additional physician work and resources. Nationwide, correct use of this code supports accurate utilization tracking and ensures clinicians are compensated for additional procedures when multiple cysts are treated.

Key payers in this national overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The analysis addresses how 19001 is used across clinical settings and payer policies that commonly affect coverage and billing for add-on procedures.

Readers will learn: the clinical context for reporting 19001 (when multiple cyst aspirations occur), typical sites of service, common payer considerations, and areas where policy or billing guidance commonly affects reimbursement. If specific national benchmarks, payer-specific edits, or local coverage determinations are relevant, they will be summarized; where input data is missing, the text will note that limited information was available. This piece focuses on procedural definition, reporting context, and the operational implications of using an add-on CPT code for additional cyst aspirations.
