Four CPT Codes, $170/Patient/Month When Fully Captured
Most practices capture 99453 and 99454 reliably. The lost revenue is almost always in 99457 and 99458 — where time tracking and documentation gaps cause systematic underbilling. Vizier tracks compliance thresholds for every code, for every patient, in real time.
Device Setup & Patient Education
Initial setup and patient education on device use and transmission. Billed once per patient per episode of care.
Device Supply with Daily Recording
16 days of data transmission required within a 30-day period. This threshold is the most common compliance failure in RPM programs.
Remote Physiologic Monitoring Treatment
Minimum 20 minutes of clinical staff interactive communication with patient per month. Live, synchronous contact required — asynchronous review alone does not qualify.
Additional 20-Minute Clinical Time
Each additional 20-minute increment of clinical time beyond the first 20 minutes. Must bill 99457 first. Significant revenue opportunity often left uncaptured.
The 16-Day Rule: Your Biggest RPM Revenue Risk
CPT 99454 requires 16 or more days of device data transmission within a 30-day period. Patients who submit readings on 15 of 30 days generate zero revenue for that month — even if all 15 readings were clinically reviewed and documented.
Vizier tracks each patient's daily transmission count in real time, identifies patients approaching day 20 without reaching 16 transmissions, and triggers automated outreach through your preferred channel — so you recapture compliant patients before the billing window closes.
The same logic applies to clinical time tracking for 99457 and 99458. If your care team has not yet reached 20 minutes of patient contact by day 25 of the month, Vizier surfaces that patient for a proactive outreach call to close the gap.
Every Device Class Has Its Own Reporting Logic
A remote vitals dashboard that treats blood pressure cuffs and continuous glucose monitors identically is not useful. Vizier maintains device-class-specific reporting — alert logic, clinical workflow integration, and outcome measures unique to each modality.

Pulse Oximeters
Masimo, Nonin, Tenovi Pulse Ox, Wellue

Cardiac & Multi-Parameter
AliveCor KardiaMobile, BioIntelliSense BioButton, Withings ScanWatch, Zio patch

AFib burden tracking, cardiology referral triage, anticoagulation candidacy review, palpitation correlation
Who Belongs in Your RPM Program
RPM demonstrates the strongest clinical and financial outcomes in patients aged 65 and above with at least one chronic condition — particularly hypertension, diabetes, heart failure, and COPD. Medicare covers RPM under Part B for these patients without requiring a separate enrollment form or beneficiary cost-sharing beyond standard Part B coinsurance.
Vizier analyzes your patient panel and identifies every patient who meets clinical eligibility criteria, has an active chronic diagnosis, and is not currently enrolled in RPM or CCM. The result is a prioritized outreach list with estimated per-patient monthly revenue and projected program size.

FAQ
RPM Analytics Questions Programs Ask Before Buying
Does Vizier work with my RPM device vendor?+
Vizier connects to the major RPM device platforms — Tenovi, Smart Meter, Withings, Omron BP cuffs, Dexcom CGM data, and others — via their published APIs. If your devices feed into a hub (HRS, BioIntelliSense, or your EHR's chronic care registry), Vizier reads from the hub. The 16-day compliance calculation and 20-minute clinical staff time documentation are derived from the same dataset.
How does the 16-day compliance tracker work mid-month?+
Vizier shows a real-time tracker for every enrolled patient: days transmitted as of today, days remaining in the calendar month, and trajectory (on track / at risk / non-compliant). Patients flagged at risk by day 8 are typically recoverable with a single outreach contact; patients flagged after day 12 rarely recover for the current billing month.
What CPT codes does Vizier track for RPM billing?+
All four primary RPM codes: CPT 99453 (initial setup and patient education), 99454 (device transmissions, requires 16+ days), 99457 (first 20 minutes of clinical staff time per month), and 99458 (each additional 20 minutes, billable up to twice per month). Vizier also tracks the related Remote Therapeutic Monitoring codes (98975, 98976, 98977, 98980, 98981) for programs running RTM alongside RPM.
How does Vizier prevent CMS audit findings on RPM?+
Audits cluster on documentation gaps for 99457 / 99458 (the 20-minute clinical staff time). Vizier runs a pre-billing validation view: of patients hitting 16 days this month, which have the time-stamped clinical staff documentation needed to defend 99457? Patients without documentation are flagged before claims drop.
What is the typical revenue impact for a 100-patient RPM program?+
At 75% compliance: ~$10,275 / month (~$123K annual). At 90% compliance: ~$148K annual. The difference between mediocre and well-run RPM analytics is a 15-percentage-point swing in compliance rate, which Vizier helps recover through mid-month outreach prompts and pre-billing validation.
Can Vizier handle RPM, RTM, CCM, and PCM in one workflow?+
Yes. The chronic care portfolio (RPM, RTM, CCM, PCM, BHI) is tracked in one analytics layer with patient-level eligibility and billing readiness across all programs. Patients eligible for multiple programs are flagged so the practice can route them appropriately.
How Many RPM-Eligible Patients Are in Your Panel?
Upload your patient roster and chronic disease diagnoses. Vizier identifies every RPM-eligible patient, models your maximum program revenue, and shows your current compliance gaps by patient and billing code.
