What "Interactive Communication" Actually Means for RPM Billing

← Back to Blog

Interactive communication is one of the most misunderstood requirements in RPM billing — and one of the most audited. CPT 99457 and CPT 99470 both require a documented interactive communication between a clinical staff member and the patient each month. Get this wrong and you're billing management codes without meeting the foundational requirement for those codes. Here's exactly what the requirement means.

What counts as interactive communication:

• A phone call between clinical staff and the patient (or caregiver) — two-way, real-time
• A video visit where monitoring data or health status is discussed
• A real-time secure messaging exchange within a patient portal where the patient actively responds

What does not count:

• Leaving a voicemail (no two-way exchange)
• Sending an automated alert or portal notification the patient doesn't respond to
• A care team discussion about the patient that doesn't include the patient
• Reviewing monitoring data without any patient contact that month

Documentation requirements: Your records must show the date of the communication, who participated (clinical staff name and role, patient or caregiver), the duration, the content discussed (what did the data show, what was communicated to the patient), and any clinical decisions that resulted. A note that says "patient contacted monthly" doesn't satisfy an auditor. A note that says "RN called patient on May 14, 2026. Discussed blood pressure readings trending elevated over past week. Patient reports medication adherence. Physician notified. No medication change at this time" does.

For practices managing 50+ RPM patients, the interactive communication workflow needs to be systematized — not left to individual clinicians to remember and document inconsistently. A monthly scheduling process, a documentation template, and a pre-billing verification step are the three pieces that make this requirement manageable at scale.
