Summary & Overview
HCPCS G9899: Mammography Results Documented and Reviewed
HCPCS Level II code G9899 denotes documentation and review of mammography results—covering screening, diagnostic, and digital breast tomosynthesis (3D) studies. This administrative imaging code captures the professional act of reviewing and recording mammography findings, distinct from the technical image acquisition. Nationally, accurate use of G9899 supports care coordination, quality measurement, and appropriate clinical follow‑up after breast imaging.
Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for use of the code, typical sites of service where documentation and review occur, and the common payer landscape for coverage considerations. The publication outlines where G9899 fits within breast imaging workflows and what to expect in claims handling.
This summary prepares readers to review benchmarks, payer policy summaries, and coding guidance sections found later in the full report.

Clinical & Coding Specifications
Clinical Context
A 52-year-old woman presents to an outpatient radiology center for routine breast cancer screening. The facility performs screening digital mammography and digital breast tomosynthesis (3D mammography). The technologist acquires screening images, which are interpreted by a board-certified radiologist. The radiologist documents the screening or diagnostic mammography results, including BI-RADS assessment, comparison to prior exams if available, and any recommended additional imaging or biopsy. The documented review of images is then recorded in the radiology report and routed to the referring provider and the patient portal. Typical site of service is an outpatient imaging center or hospital outpatient department. The service type is diagnostic and screening breast imaging interpretation and documentation of results for film, digital, or digital breast tomosynthesis (3D) mammography, corresponding to administrative and clinical review of mammography images and formal reporting.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required to document and review mammography results is substantially greater than usual due to complexity of interpretation or extensive review of prior studies and records. |
