Automated billing across a large monitored population.
RPM Billing (CPT 99453-99458)
RPM billing automation for CPT 99453-99458 that survives an audit
We turn RPM activity into clean, defensible claims — 99453 setup, 99454 device supply, and 99457/99458 management time — by enforcing the 16-day and 20-minute rules in-product and generating 837P claims with a complete audit trail.

What RPM billing automation actually involves
RPM reimbursement looks simple — four CPT codes — but the money is won and lost in the rules behind them. CPT 99454 requires at least 16 days of device readings in a 30-day period. CPT 99457 covers the first 20 minutes of care-management time per calendar month, and 99458 each additional 20 minutes. Miss the threshold or fail to document the minutes, and the claim is denied or, worse, clawed back on audit.
We build billing as a first-class part of the RPM platform: automatic 16-day threshold tracking, a per-patient monthly timer with a documented interaction log, eligibility and 99453 one-time-setup logic, and 837P claim generation with the right modifiers and ICD-10 linkage. The goal is claims that are both clean and defensible.
The codes
What CPT 99453-99458 actually cover
The RPM code family maps to the work of a monitoring program. 99453 is the one-time setup and patient education. 99454 is the monthly device supply and data transmission, requiring at least 16 days of readings. 99457 is the first 20 minutes of care-management time in a calendar month, and 99458 is each additional 20 minutes.
Getting paid means proving each element: setup happened once, the 16-day threshold was met, and the minutes were spent and documented. We build the tracking and evidence for all four codes so billing is automatic and defensible.

What we automate in RPM billing
Every rule that decides whether a CPT 99453-99458 claim gets paid — encoded in the product.
CPT 99453 setup billing
One-time setup and patient education billed once per episode, with logic that prevents duplicate 99453 charges across a patient's monitoring lifetime.
CPT 99454 threshold tracking
Automatic monitoring of the 16-days-of-readings-in-30 requirement, flagging at-risk patients before the window closes so the device-supply claim isn't lost.
CPT 99457/99458 time capture
A per-patient, per-calendar-month timer that captures the first 20 minutes (99457) and each additional 20 minutes (99458) of care-management time, with a documented interaction log.
Eligibility & denial guards
Pre-claim checks for consent, established-patient status, and code-combination rules that catch the errors payers deny for — before the claim is submitted.
837P generation & audit trail
Clean X12 837P professional claims with modifiers and ICD-10 linkage, plus an immutable audit trail so every billed minute and reading is defensible under review.

Our Process
How we ship RPM billing automation
We encode the reimbursement rules as product logic, so clean claims are the default and denials are the exception.
1.
Billing rule discovery
We map your payer mix and codes to the 99453-99458 rules — thresholds, time increments, and modifier requirements — and design the billing data model.
Rules-mapped
2.
Threshold & timer build
16-day tracking and the per-month care-management timer, with interaction logging wired to clinician identity.
Threshold-safe
3.
Claim generation
837P output with modifiers, ICD-10 linkage, and eligibility guards, validated against real denial patterns.
Clean claims
4.
Clearinghouse & reconciliation
Connection to your billing system or clearinghouse, remittance (835) reconciliation, and denial dashboards.

Why Partner With Us
15-Minute Scoping CallWhy teams automate RPM billing with Agnotic
We treat reimbursement as software, so revenue doesn't leak at the thresholds.
Audit-defensible by design
Every reading and minute is logged against identity and time, so claims hold up when a payer looks.
Fewer denials, faster cash
Pre-claim eligibility and code-combination guards catch the errors payers deny for before submission.
Reimbursement depth
We encode the 16-day and 20-minute rules precisely, not approximately — the difference between paid and clawed back.

Frequently Asked Questions
A billing module — threshold tracking, time capture, and 837P generation — typically starts in the mid five figures, less when it's built alongside a broader RPM platform. Clearinghouse integration and 835 reconciliation extend the range. The investment usually pays back quickly in recovered denials and captured thresholds.
