Summary & Overview
HCPCS M1212: Glycemic Status Assessment Missing
HCPCS Level II code M1212 denotes that a patient’s glycemic status assessment—specifically hemoglobin A1c (A1c) or glucose management indicator (GMI)—is missing or was not performed during the measurement period. The code serves as a documentation tool in quality measurement and reporting workflows to flag absent glycemic data for patients expected to have routine monitoring. Nationally, this code is relevant to diabetes care quality metrics, value-based contracts, and reporting programs that track A1c performance and gaps in care.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the code’s purpose and clinical context, typical sites of service, common usage patterns, and the implications for quality measurement and documentation. The publication also summarizes benchmarks and policy considerations where available and notes when input data are not provided.
This briefing is designed for clinicians, practice managers, billing and compliance staff, and policy analysts seeking a concise reference on M1212—what it represents, why it matters for national diabetes care monitoring, and how it fits into documentation and reporting workflows. Data not available in the input are clearly identified where applicable.
Billing Code Overview
HCPCS Level II code M1212 indicates that a glycemic status assessment (hemoglobin A1c or glucose management indicator) level is missing or was not performed during the measurement period. This code documents the absence of a recorded A1c or GMI result for a patient when such measurement is expected as part of diabetes or glycemic management monitoring.
Service Type: Glycemic status assessment reporting / quality measurement exception
Typical Site of Service: Outpatient clinics, primary care offices, endocrinology practices, and other ambulatory care settings where diabetes monitoring is performed
Clinical & Coding Specifications
Clinical Context
A primary care clinician documents a patient with known type 2 diabetes mellitus who had no recorded glycated hemoglobin measurement during the designated measurement period. The patient presents for a routine chronic care visit; the clinician reviews medication adherence, home glucose logs, and acute events but the laboratory HbA1c was not completed because the patient declined blood draw or missed a scheduled phlebotomy appointment. The practice bills M1212 to indicate the glycemic status assessment level (HbA1c or GMI) is missing or was not performed during the measurement period. Typical workflow steps: ordering an HbA1c or continuous glucose monitoring report, attempting phlebotomy or coordinating remote testing, documenting reason for missing measurement in the encounter note, and applying an appropriate modifier if additional circumstances affect billing or payment adjudication. Typical site of service: outpatient clinic, primary care office, or telehealth visit when labs were not completed. Typical patient scenario: adult with diabetes managed in primary care who missed or declined lab testing within the reporting period, or whose CGM-derived metrics were unavailable for the performance measure.
