Summary & Overview
HCPCS Level II M1285: Mammography Results Not Documented and Reviewed
HCPCS Level II code M1285 indicates that screening or diagnostic mammography results — including film, digital, or digital breast tomosynthesis (3D) — were not documented and reviewed, with the reason listed as not otherwise specified. Nationally, this code highlights gaps in documentation workflows for breast imaging and can affect quality measurement, continuity of care, and downstream clinical follow-up. The code does not describe the imaging service itself but serves as an administrative marker that result review documentation is missing.
Key payers in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code's clinical and administrative purpose, typical sites of service, common contexts where the code may appear, and the kinds of benchmarks and policy updates that influence coding and documentation practices. The publication outlines how M1285 is used in claims reporting, implications for quality measurement and compliance, and where data limitations exist.
This summary is designed for national audiences — including billing professionals, radiology administrators, and payers — seeking a clear, practical description of HCPCS Level II code M1285, its relevance to mammography documentation, and the types of information presented in the full publication.
Billing Code Overview
HCPCS Level II code M1285 denotes that screening or diagnostic mammography results (film, digital, or digital breast tomosynthesis/3D) were not documented and reviewed, with the reason recorded as not otherwise specified. This code is used to indicate the absence of a documented review of mammography results rather than to describe the imaging procedure itself.
Service type: Documentation/administrative reporting related to breast imaging result review
Typical site of service: Imaging centers, hospital outpatient radiology departments, breast clinics, and ambulatory care settings where mammography is performed and results are expected to be documented and reviewed
Data not available in the input.
Clinical & Coding Specifications
Clinical Context
A 56-year-old woman presents for routine breast cancer screening with a screening digital mammogram and digital breast tomosynthesis (3D mammography). The technologist performs image acquisition and uploads images to the radiology information system, but when the interpreting radiologist reviews the case, the imaging results are not documented in the official report and there is no documented review in the electronic medical record. The study is flagged in the workflow as "images acquired — no result documented." The radiology team documents the reason as "not otherwise specified" because the original images are available but the final interpretation and report were not completed due to an administrative/communication lapse. Typical workflow steps include patient check-in at an outpatient imaging center, technologist image acquisition, image transmission to PACS, radiologist review and final report generation, and result delivery to the referring provider and the patient portal. Site of service is an outpatient imaging center or hospital-based outpatient radiology department. The service type is diagnostic/screening mammography where results were not documented and reviewed, coded using M1285 to indicate lack of documented review and final report for a film, digital, or digital breast tomosynthesis mammogram.
