Remote patient monitoring (RPM) is transforming maternity care by enabling more connected, proactive prenatal and postpartum support, especially for high-risk patients and those facing social or geographic barriers. The 2025 CMS updates to RPM billing codes, including CPT 99453, 99454, 99457, 99458, and G0511, offer maternity providers a framework to both improve outcomes and sustain their programs financially.

Used correctly, these codes support hybrid prenatal care, postpartum monitoring, and high-touch risk management, while aligning with national guidelines and value-based models.

Billing Requirements for RPM in 2025

To ensure compliance and reimbursement, maternity providers should follow these CMS requirements:

  • RPM devices must be FDA-defined medical devices
  • Patients must opt-in and provide consent
  • A new patient evaluation must be completed prior to RPM initiation
  • 16 days of device usage per month is required for 99453 and 99454 (through 2025; expected to change in 2026)
  • Data must be automatically transmitted and HIPAA-compliant
  • Documentation of time spent and interactive communication is required for 99457 and 99458

2025 Maternity-Relevant RPM CPT Codes and Reimbursement Rates

CPT 99453
This code reimburses providers for the initial setup and patient education for remote monitoring devices—like blood pressure cuffs, weight scales, or glucose monitors. In a maternity setting, it’s critical for onboarding patients into RPM programs early, especially those at risk for hypertension or gestational diabetes.

CPT 99454
Used for the monthly supply of RPM devices and the automatic transmission of patient data, this code supports ongoing remote monitoring of vitals over the course of pregnancy. Patients must transmit data on at least 16 days per month. It’s perfect for tracking weight gain, blood pressure trends, and postpartum recovery markers.

CPT 99457
This code reimburses for the first 20 minutes of care management each month, including real-time communication with the patient (e.g., phone or video). In maternity care, this supports proactive engagement with high-risk or socially complex patients between visits, helping to close care gaps.

CPT 99458
For patients who need more attention, 99458 adds payment for each additional 20-minute increment of RPM services beyond the initial 20 minutes. It allows maternity teams to be reimbursed for the full scope of time spent managing patient data and coordinating care for complex pregnancies.

G0511 (FQHC/RHC RPM)
This HCPCS code is for Federally Qualified Health Centers (FQHCs) and Rural Health Clinics (RHCs) providing 20 minutes of RPM care per month under practitioner supervision. It’s a powerful tool for bringing high-quality, tech-enabled maternity care to underserved rural or safety-net populations.

Why RPM CPT Codes Matter for Maternity Clinics

These codes are foundational to creating sustainable, hybrid prenatal and postpartum programs:

  • 99453 enables reimbursement for device setup and patient onboarding – vital for early engagement in high-risk pregnancies
  • 99454 supports recurring monitoring of vitals like BP and weight – essential for detecting preeclampsia, gestational diabetes, or mental health risk
  • 99457 and 99458 reimburse care teams for the time they spend reviewing data and personally interacting with patients – work that often goes unreimbursed
  • G0511 allows FQHCs and RHCs to offer RPM in underserved and rural areas, expanding access to quality maternity care

Aligned With National Guidelines and Quality Frameworks

RPM using these codes supports performance on key maternity-focused goals:

  • American College of Obstetricians and Gynecologists (ACOG):  Supports hybrid prenatal models, individualized risk-based care, and fourth-trimester care
  • USPSTF: Encourages consistent tracking of maternal health metrics like blood pressure and glucose
  • NCQA / HEDIS: Helps meet Prenatal & Postpartum Care, Blood Pressure Control, and Depression Screening 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: Enables remote surveillance for Severe Hypertension, Postpartum Complications, and Mental Health
  • MiPATH: Reduces in-person appointments and advances personalized, patient-preference-centered prenatal care through data-driven decision-making
