What CPT codes does Medicare use for remote patient monitoring?

Medicare's RPM framework is generally built around four CPT codes: 99453 for initial setup and patient education on a monitoring device, 99454 for supplying the device and collecting/transmitting daily readings over a defined period, 99457 for the first 20 minutes of clinical staff time managing and reviewing the data each month, and 99458 for each additional 20-minute increment of that management time. Exact code definitions and any add-on codes should be confirmed against the current CMS Physician Fee Schedule.

What is the 16-day data requirement in Medicare RPM billing?

For the device-supply component of RPM (billed under a code like 99454), Medicare has historically required that a patient transmit physiologic data on at least 16 of the 30 days in the billing period before that component can be billed for the month. This threshold is a rule set through CMS rulemaking and is subject to change, so it should be verified for the current year.

Does Medicare require direct supervision for RPM services?

RPM treatment management services have generally been billable under general supervision, meaning the billing practitioner does not need to be physically present while clinical staff review data or communicate with the patient, as long as the practitioner is available to provide direction. Supervision levels are set by CMS and can be revisited in annual rulemaking, so practices should confirm the current requirement rather than assume it carries over year to year.

Do Medicare patients pay anything out of pocket for RPM?

RPM services billed under Medicare Part B are generally subject to standard Part B cost-sharing, which typically means the patient owes coinsurance after any applicable deductible, unless they have a supplemental plan, Medicare Advantage plan, or Medicaid coverage that reduces or eliminates that share. The exact coinsurance amount depends on the fee schedule rate for that year and the patient's specific coverage, so it should be verified case by case.

Medicare RPM Coverage in 2026: What's Covered and What Changed

7 min read · Updated July 2026

Medicare has covered remote patient monitoring for several years, but the codes, supervision rules, and payment rates that govern it are reset every year through CMS rulemaking. Here's how the coverage is structured, and where to check the current-year details before you bill.

How Medicare RPM coverage is structured

Remote patient monitoring (RPM) is paid under Medicare Part B through the annual Physician Fee Schedule (PFS). Rather than one code covering the whole service, RPM is built from several distinct CPT codes that each represent a separate piece of the workflow: setting up the device, collecting data, and having clinical staff review and act on it. A practice typically bills more than one of these codes together over the course of a monitoring period, and each code has its own requirements that must be independently satisfied.

Because RPM sits inside the broader PFS, it is subject to the same annual cycle as every other physician service: CMS proposes changes each summer, takes public comment, and finalizes a rule in the fall that takes effect the following January. That means code definitions, supervision policy, frequency limits, and payment rates can all shift from one year to the next — sometimes modestly, sometimes more substantially.

The core RPM codes

The four codes most commonly associated with Medicare RPM are summarized below. This table describes what each code is generally intended to capture — not payment amounts, which change annually and vary by locality.

Code	What it covers
99453	Initial setup of the monitoring device and education of the patient on its use, billed once per episode of care.
99454	Supply of the device and the ongoing collection and transmission of physiologic data, billed on a recurring monthly basis when the data-day threshold for that period is met.
99457	The first 20 minutes, in a calendar month, of clinical staff time spent reviewing monitoring data and engaging in interactive communication with the patient or caregiver.
99458	Each additional 20-minute increment of that same monthly management time, billed alongside 99457 when more time is furnished.

Some years CMS has also addressed shorter monitoring periods or additional nuances for these services through subregulatory guidance. Always confirm the current code set, short descriptors, and any newly introduced or retired codes in the current-year PFS final rule before building a billing workflow around them.

The 16-day data requirement

For the device-supply component of RPM, Medicare has generally required that a patient transmit physiologic data on a minimum number of days within each 30-day period — historically 16 of 30 days — before that component can be billed for the month. This threshold exists to distinguish genuine ongoing monitoring from a single data pull, and it is a policy choice CMS can revisit. Practices should verify the applicable day count and period length for the current year rather than assuming last year's threshold still applies.

Supervision and consent basics

RPM treatment management services (the time-based codes) have generally been billable under general supervision, meaning the billing practitioner does not need to be in the room, or even on site, while clinical staff review data or talk with the patient — as long as the practitioner is available to provide direction if needed. This is a more flexible standard than direct supervision, and it's part of what makes RPM workable for smaller primary care and endocrinology practices.

Alongside supervision, Medicare has generally expected:

A practitioner order for RPM as part of the patient's plan of care.
Documented patient consent, since RPM typically involves ongoing collection and coinsurance obligations the patient should understand up front.
An established relationship between the billing practitioner and the patient, consistent with how Medicare defines the RPM service.
Use of an FDA-defined medical device capable of automatically collecting and transmitting data, rather than patient self-reported readings.

Supervision and consent policy, like the codes themselves, is set through annual rulemaking and can be refined from year to year, so it is worth a fresh check each January.

What patients pay

RPM services billed under Medicare Part B are generally subject to standard Part B cost-sharing. In practice, that typically means the patient is responsible for coinsurance on each RPM code billed, after any applicable deductible, unless a Medicare Supplement (Medigap) policy, Medicare Advantage plan, or Medicaid coverage reduces or eliminates that share. Because coinsurance is a percentage of the fee schedule rate, and the fee schedule rate itself is reset annually, the dollar amount a given patient owes will vary by year and by which codes are billed. Practices that want to give patients an accurate estimate should calculate it from the current-year fee schedule rather than a prior year's numbers.

Why rates and rules update annually

CMS is required to review and update the Physician Fee Schedule every year, adjusting relative value units, conversion factors, and specific policies based on public comment, budget neutrality requirements, and evolving clinical evidence. RPM has been a relatively young and fast-evolving part of the fee schedule, so it has seen more year-over-year policy attention than many long-established services — including changes to supervision flexibilities, data-collection periods, and how RPM interacts with other care management services. Treat any specific figure or rule you read about Medicare RPM, including in this article, as a snapshot that needs to be checked against the current year's official guidance before it's used for billing decisions.
