HCPCS Level II M1255: Positive Pregnancy Test During Non-Obstetric Clinic Visit
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.

Clinical & Coding Specifications
Clinical Context
A 28-year-old patient presents to a primary care clinic for an unrelated complaint — for example, evaluation of a urinary tract infection or seeking contraception counseling. A point-of-care urine pregnancy test returns positive, but the patient states she will not establish prenatal care at this clinic (plans to terminate the pregnancy or seek prenatal care elsewhere). The clinic documents the positive pregnancy test result, provides counseling or referral as appropriate, and bills the encounter using M1255 to indicate a positive pregnancy test in a patient seen for another primary reason. The clinical workflow typically includes obtaining the reason for visit, performing the pregnancy test, documenting informed discussions about options and referrals, placing orders or referrals (e.g., OB intake, family planning, or abortion services), and recording the patient’s plan not to establish prenatal care at the clinic. Vital signs, relevant physical exam, and any treatment for the primary complaint are documented in the medical record.

22 | Increased procedural services | Use when work required is substantially greater than typically required for the service due to complexity of the unrelated visit and additional counseling about pregnancy options. |
