HCPCS Level II M1286: BMI Outside Normal Parameters, Follow-Up Not Completed

HCPCS Level II code M1286 documents that a patient’s body mass index (BMI) is outside normal parameters and that a follow-up plan was not completed due to a documented medical reason. As a documentation-focused code, M1286 is used to capture clinical context around BMI management and recordkeeping rather than a discrete therapeutic service. Nationally, accurate use of this code matters for quality measurement, care coordination, and administrative records where BMI and follow-up plans influence risk stratification and subsequent care decisions. Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Readers will find an overview of the code’s clinical meaning, common sites of service and service type, and how the code fits into documentation and quality workflows. The publication outlines typical payer coverage considerations and common modifiers associated with administrative and clinical reporting (modifiers list provided in source data). It also highlights where data is not available in the input, including associated taxonomies, ICD-10 diagnoses, related codes, and specific service-line mappings. The goal is to give clinicians, billing staff, and policy analysts a concise reference for when and why M1286 may appear on claims and charts, and what contextual elements are typically associated with its use.

Billing Code Overview

HCPCS Level II code M1286 indicates that body mass index (BMI) is documented as being outside of normal parameters, and a follow-up plan is not completed for a documented medical reason. This entry reflects documentation status rather than a specific treatment procedure.

Service type: Documentation and clinical assessment follow-up planning related to abnormal BMI
Typical site of service: Outpatient clinical settings such as primary care offices, specialty clinics, or other ambulatory care sites where BMI is assessed and follow-up planning is documented

Clinical & Coding Specifications

Clinical Context

A typical patient scenario involves an adult patient presenting to a primary care clinic or outpatient community health center for chronic disease management or preventive care. Vital signs are measured, including height and weight, and body mass index (BMI) is calculated and documented. The BMI is recorded as outside normal parameters (underweight, overweight, or obese). A follow-up plan (for weight management, nutrition counseling, or medical evaluation) is not completed because of a documented medical reason such as acute intercurrent illness, recent hospitalization, unstable vital signs, or an immediate medical contraindication to initiating weight-management interventions. The clinical workflow includes: initial intake and vital signs, clinician review of BMI, documentation of reason for deferring follow-up plan in the medical record (e.g., acute infection, post-operative recovery, or hemodynamic instability), and scheduling or planning definitive management at a later, medically appropriate visit. Typical sites of service are outpatient primary care offices, community clinics, and ambulatory care centers. Typical patient examples include: an older adult recently hospitalized for pneumonia with temporarily unstable status where weight-management counseling is deferred, or a patient with acute myocarditis where initiating an exercise or weight-loss plan is postponed for clinical safety.

207RP1001X	Physician Assistant	Physician assistants commonly document vitals and coordinate deferred follow-up plans.
363LP0800X	Nurse Practitioner	Nurse practitioners routinely assess BMI and document medical reasons for deferral.
208D00000X	General Practice	General practitioners in outpatient settings perform BMI screening and document deferral reasons.

CPT Code	Description	Relationship to This Procedure
`99213`	Office or other outpatient visit for the evaluation and management of an established patient, typically 15 minutes	Commonly used for follow-up or problem-focused visits where BMI is reviewed and a follow-up plan would be documented or deferred.
`99401`	Preventive medicine counseling, individual; approximately 15 minutes	Used when brief counseling for weight management or lifestyle modification is provided when not deferred.
`99406`	Smoking and tobacco use cessation counseling visit, intermediate, 3-10 minutes	Often associated in preventive counseling visits where lifestyle modification discussions occur alongside BMI assessment.
`97802`	Medical nutrition therapy; initial assessment and intervention, individual, face-to-face, 15 minutes	Used when a nutrition follow-up plan is completed; absence of this after BMI abnormality may be documented as deferred for medical reasons.
`G0438`	Annual wellness visit, initial preventive visit, includes personalized prevention plan	Used when BMI screening occurs as part of a wellness visit and follow-up planning may be deferred due to acute medical issues.
