HCPCS S9001: Home Uterine Monitor With or Without Nursing Services
HCPCS Level II code S9001 designates a home uterine monitor provided with or without associated nursing services. The code captures remote maternal monitoring delivered in the patient’s home and reflects growing adoption of home-based surveillance for uterine activity and preterm labor risk. Nationally, use of home monitoring devices influences outpatient care pathways, resource allocation for home nursing, and payer coverage policies for maternal-fetal surveillance.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.

Clinical & Coding Specifications
Clinical Context
A typical patient is a pregnant person at risk for preterm labor or with prior preterm birth who is discharged home for outpatient monitoring of uterine activity. The home uterine monitor (S9001) may be provided with or without associated nursing services. Clinical workflow: a prenatal clinician (obstetrician, maternal-fetal medicine specialist, or perinatal nurse) determines need for home monitoring based on history (prior spontaneous preterm birth, short cervix, uterine irritability, or intermittent contractions). The device is issued and the patient receives education on application and symptom reporting. Nursing staff may perform set-up, daily or intermittent remote checks of transmitted data, triage calls for abnormal patterns, and coordination of in-person evaluation if sustained contractions, nonreassuring signs, or labor is suspected. Device transmission or patient logs guide decisions for clinic return, corticosteroid administration, or escalation to inpatient care. Typical site of service is the patient’s home, with device setup and any associated teaching or nursing contacts documented in the outpatient or home health record.
