HCPCS Level II code M1255 denotes services for patients who present to a clinic for a non-prenatal or non-postpartum visit, are found to have a positive pregnancy test, and have not established the clinic as their obstetric provider. The code captures an important intersection of reproductive health screening and ambulatory care workflows, where counseling, pregnancy-related documentation, and disposition planning may be required without initiating formal prenatal care.

This national summary covers payer policies from major commercial and public insurers and highlights common implementation considerations. Key payers included are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context and service setting, typical claims handling considerations, and what to expect in coverage and billing practice nationally. The publication discusses benchmarks and policy updates where available and clarifies which aspects of coding and billing are addressed by M1255 versus other obstetric or pregnancy-related codes.

Intended audiences include billing professionals, clinic administrators, and policy analysts seeking concise guidance on how M1255 is used to document episodic pregnancy-related findings in non-obstetric ambulatory visits. Data not available in the input will be identified as such within detailed sections.
