CPT 99457 reimburses providers for the active management of patients enrolled in remote monitoring, including at least 20 minutes per month of care team activity and real-time interaction with the patient or caregiver. In maternity care, this unlocks a powerful way to stay closely connected to expectant patients, especially those with clinical or social risks, without requiring in-person visits.

For high-risk patients, those with gestational hypertension, diabetes, or other complication, ongoing review of data and live interaction enables earlier interventions and better pregnancy outcomes. For low-risk patients, 99457 supports reduced travel and clinic time while maintaining the same standard of care. And for providers, it ensures that this essential behind-the-scenes work is fully reimbursed and financially sustainable.

Beyond reimbursement, CPT 99457-based care directly aligns with national quality standards and guidelines, including:

  • American College of Obstetricians and Gynecologists (ACOG): Endorses the use of remote monitoring to extend prenatal care and reduce disparities in access.
  • USPSTF: Recommends regular monitoring of maternal blood pressure, glucose, and weight to prevent perinatal complications.
  • NCQA/HEDIS: Supports remote management as a method to meet timeliness of prenatal care, postpartum follow-up, and blood pressure control measures.
  • AMA: Advocates for digital tools like RPM to support maternity care management, shared decision-making, and equity in care access.
  • AIM Patient Safety Bundles: by enabling continuous remote monitoring of vital signs and symptoms for early identification and timely response to conditions like hypertension
  • MiPATH recommendations by facilitating personalized, data-driven prenatal care through remote monitoring
