Summary & Overview
HCPCS Level II M1258: Cardiovascular Risk Assessment, Documented Risk Score
HCPCS Level II code M1258 denotes a cardiovascular disease (CVD) risk assessment with a documented calculated risk score. The code captures the clinical action of formally assessing and recording a patient’s estimated risk for cardiovascular events, a key component of preventive care and chronic disease management. Nationally, structured risk assessment supports evidence-based decision-making for interventions such as lifestyle counseling, pharmacotherapy initiation, and referral to specialists.
Key payers for this code include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of what the code represents, payer inclusion in the analysis, and the clinical context for use. The publication summarizes typical sites of service, common billing modifiers and administrative considerations, and where available, benchmark metrics and coding guidance. It also highlights policy and payer coverage considerations relevant to documenting a calculated risk score.
This summary is intended for health system administrators, practice managers, and clinicians seeking a national-level reference on the clinical and billing meaning of M1258 and what to expect when a documented CVD risk score is part of the medical record.
Billing Code Overview
HCPCS Level II code M1258 represents a cardiovascular disease (CVD) risk assessment with a documented calculated risk score. This service documents that a clinician performed a formal risk stratification for cardiovascular disease and recorded a numeric or categorical risk estimate.
Service type: Risk assessment / clinical evaluation
Typical site of service: Outpatient clinical settings, including primary care offices and preventive cardiology visits, where clinicians assess cardiovascular risk and document a calculated score.

Clinical & Coding Specifications
Clinical Context
A 58-year-old patient with hypertension and borderline hyperlipidemia presents to a primary care clinic for an annual chronic disease follow-up. The clinician performs a cardiovascular disease (CVD) risk assessment during the visit, documents measured vitals (blood pressure, height, weight), recent labs (fasting lipid panel, hemoglobin A1c), smoking status, age, sex, and medication list, and calculates a 10-year atherosclerotic cardiovascular disease (ASCVD) risk score using a validated calculator. The calculated risk score is recorded in the medical record along with the data elements used and any brief counseling or management decisions. Typical workflow: patient arrival and vitals → clinician review of history and medications → point-of-care or EHR-integrated risk calculator run → documentation of calculated risk score and clinical interpretation → care plan noted (e.g., lifestyle modification, statin consideration) and appropriate orders placed. Typical site of service: outpatient primary care clinic, family medicine, internal medicine, cardiology clinic, or preventive health visit.
