Hypertension
The highest-volume remote monitoring program in Medicare, and the easiest one to run badly.
Hypertension is where most clinics start and where most clinics get audited. The clinical case is settled: home readings predict cardiovascular events better than office readings, and titrating against a 28-day mean beats titrating against whatever the pressure happened to be in the hallway. The operational case is harder. A hypertension program only pays if the cuff actually transmits, and cuffs stop transmitting for reasons that are almost never clinical: the patient moved the base station, the cellular module lost its APN, the cuff is the wrong size and hurts.

Signal stack
What gets measured, from where, and why it earns its place
Every source is tagged at ingest as billable or context-only. Context-only data is clinically valuable and never enters a device-supply line.
Blood pressure
Cellular oscillometric cuff, validated for the patient's arm circumference
Two seated readings morning and evening. Gathermed keeps the raw pairs, not just the average, because the second reading is the one that counts clinically.
Heart rate
Same cuff
Rate-pressure product trend catches the patient whose pressure looks controlled because they are tachycardic and volume depleted.
Weight
Connected scale, optional
Two kilograms in three days on a thiazide changes the interpretation of every pressure in the window.
Medication adherence
Patient-reported, three taps
Context only. Never rolled into an RPM device-supply line.
Escalation design
Thresholds, and who has to do something about them
Red marks a same-day or immediate pathway. Amber marks a review within the stated window. Each one is assigned to a named clinician with a response clock, not to a queue.

Program operation
How the month actually runs
Order written against a documented diagnosis and a titration plan the readings will change.
Cuff sized at enrollment, not shipped blind. Wrong cuff size is the top cause of dead programs.
Setup call, 98% of which is teaching arm position. Bill 99453 once.
Days 1-20: transmission counter runs. Silent for 48 hours triggers outreach before it becomes a coding problem.
Day 30: counter picks the device code. 16+ days bills 99454, 2-15 days bills 99445.
Management time logged against the actual review, with the interactive call timestamped.

The rules that break programs
One billing clinician per 30-day episode. RPM and RTM are not additive in the same calendar month. Duration codes are mutually exclusive. Management time requires at least one real-time interactive communication. Medical necessity precedes enrollment.
Sponsor view
If you are a manufacturer looking at this condition
Antihypertensive persistence collapses at around six months, and the newer resistant-hypertension agents live or die on whether prescribers can see a pressure response before the patient gives up. A sponsored program gives you consented, time-stamped home pressure trajectories on therapy, titration latency, and discontinuation reasons in the patient's own words. That is a real-world evidence asset. It is not a billing play for you, and the structure matters enormously — see the sponsorship note below.
Read this before you fund anything
Sponsor-funded monitoring that produces billable revenue for prescribers is remuneration to referral sources under the federal Anti-Kickback Statute. The structures that survive scrutiny keep the sponsor's data interest and the provider's billing interest completely separate. The three structures we will build, and the one we will not.
Questions
Hypertension monitoring, answered directly
Can a patient use their own blood pressure cuff?
Only if it is a cleared device for the measured parameter and it transmits data automatically. Self-entered readings from an unconnected cuff do not support the device-supply codes.
How many days of data do we need in 2026?
Two. As of January 2026, 99445 covers 2 to 15 transmitted days in a 30-day period at the same rate as 99454. You bill one or the other, never both.
Does a nurse have to make the call?
Clinical staff time counts toward 99457 or 99470 under general supervision, but the month needs at least one real-time interactive communication with the patient or caregiver.
