RPM billing is a monthly arithmetic exercise: setup once per patient (99453), device supply every 30 days with the required data transmission days (99454), and treatment management in time tiers (99457 at 20+ minutes, 99458 add-on at 40+). Telehealth is a policy exercise: place-of-service codes, modality requirements and coverage rules that CMS and payers revise repeatedly. Both reward discipline and punish improvisation.
Start with RPM thresholds. 99454 requires 16 days of transmitted readings in each 30-day period — a device that works but a patient who stops wearing it means the month is not billable, and booking it anyway creates audit exposure at scale. 99457 requires 20 minutes of interactive treatment management per calendar month by clinical staff, with 99458 adding a second 20-minute tier. We maintain per-patient ledgers so each month's billable position is known in real time.
Consent and enrollment are the quiet audit anchors: written or documented consent to RPM participation, device training notes, and program agreements — all of which must exist before the first month bills. Our onboarding workflow assembles the consent pack with the program setup so month one is compliant from day one, not retrofitted after a record request.
Telehealth coding follows current-year CMS and payer policy: the appropriate place-of-service code (including 02 and 10 distinctions), modifiers where required, and modality rules — including the circumstances where audio-only behavioral health services are covered. Because Congress and CMS revise telehealth rules repeatedly, we re-verify coverage quarterly and adjust coding templates ahead of policy transitions rather than after denials arrive.
