The four codes
| Code | Covers | Key requirement |
|---|---|---|
| 99453 | Initial setup and patient education on the device | Billed once per episode of care, at setup |
| 99454 | Device supply with daily recordings or programmed alerts, per 30 days | Readings transmitted on 16 or more days of the 30-day period |
| 99457 | First 20 minutes of clinical staff/physician time per calendar month: data review plus interactive communication with the patient | At least 20 documented minutes including live interaction |
| 99458 | Each additional 20 minutes of that management time | Billed with 99457, never alone |
The model these codes pay for is the one HHS describes in its RPM guidance HHS telehealth.hhs.gov2026-08: connected devices transmitting physiologic data to a managing clinical team.
Current rates: use the lookup, not a blog table
Dollar amounts for each code are set by the CMS Physician Fee Schedule, revised in an annual final rule effective each 1 January and varying by locality. The authoritative current figure for any code and place of service comes from the CMS PFS lookup tool CMS Physician Fee Schedule lookup2026-08. This site deliberately does not print rate dollars that expire every January; the source register records this refresh cadence, and any page quoting RPM reimbursement dollars without a year and locality attached is out of date by design.
How the codes stack in a typical month
month 1: 99453 (setup) + 99454 (device, 16-day rule met) + 99457 (20 min)
ongoing months: 99454 + 99457, adding 99458 per extra 20 minutes
a month missing the 16-day threshold: no 99454; time codes bill only if their minutes and interaction happened
The two gating rules do the compliance work: the 16-day device rule for 99454 and the 20-minute interactive-time rule for 99457. Both are documentation disciplines as much as clinical ones, and both are exactly where audits look first.
