Can CPT Codes 99453 and 99454 Be Billed Together in 2026?

Key Takeaways for 99453 and 99454 in 2026

1. CPT codes 99453 and 99454 can be billed together in 2026 for the first 30-day RPM episode when patients transmit data for at least 16 days from FDA-approved devices.
2. 99453 covers initial setup and patient education once per patient lifetime with a Medicare rate of $18.75, while 99454 covers device supply and monthly data transmission at $49.10.
3. Common denials come from too few data days, manual uploads, or duplicate claims, and teams can prevent them by tracking logs and using automatic transmission only.
4. 2026 Medicare updates keep RPM codes active without new bundling limits and introduce short-duration options like 99445 that complement 99453 and 99454.
5. Rhythm360 automates cardiology RPM compliance across CIEDs and physiologic devices, supporting up to 300% revenue growth; schedule a demo today to reduce denials.

CPT Code 99453 and 99454: What Each Code Covers

CPT 99453 maintains a national non-facility payment rate of $18.75, while CPT 99454 increased slightly to $49.10 in 2026. Practices typically use these codes together in the first 30 days for cardiology RPM, such as heart failure patients using blood pressure cuffs and scales alongside CIED monitoring. Patients must transmit RPM data using the device for at least 16 days per month to bill CPT 99453 and 99454 together. CPT code 99454 billing guidelines require automatic data transmission from FDA-approved devices, so manual uploads do not qualify for reimbursement.

Rules for Billing 99453 and 99454 Together in 2026

Clinics can use this compliance checklist to bill both codes correctly.

1. 16+ days data transmission requirement: CPT 99454 requires device supply with daily recording or alert transmission for 16–30 days in a 30-day period.
2. Unique patient and episode billing: 99453 is billable once per patient lifetime for the initial setup service.
3. No overlap with mutually exclusive codes: CPT 99445 (2-15 days) cannot be billed with CPT 99454 (16-30 days).
4. FDA-approved automatic transmission: Manual data uploads disqualify claims for 99454.
5. HIPAA-compliant data collection: Data collection must maintain HIPAA compliance standards.

In a cardiology example, a heart failure patient using a blood pressure cuff and scale who transmits data for 20 days qualifies for both 99453 for initial setup and 99454 for device supply. CPT 99453 can be billed once per patient for that initial training and configuration. Teams bill 99454 when the patient reaches at least 16 days of automatic data transmission within each 30-day period.

Common 99454 Denials and Five Practical Fixes

Top denial reasons for CPT 99454 include billing for fewer than 16 days of device usage, submitting multiple claims for different devices for the same patient, and using non-FDA-approved devices. The following fixes address these issues directly.

1. Denial: Less than 16 days of data → Fix: Track transmission logs daily and bill 99445 for 2-15 days instead when appropriate.
2. Denial: Duplicate device claims → Fix: Submit only one CPT 99454 claim per patient per month, regardless of the number of devices.
3. Denial: Manual data uploads → Fix: Use only FDA-approved devices that send data automatically without patient entry.
4. Denial: Overlapping service periods → Fix: Align billing cycles for 30-day device supply codes and avoid double-counting RPM time with other services.
5. Denial: Insufficient documentation → Fix: Maintain complete daily device transmission logs for each billing period.

Medicare 2026 RPM Coverage and New Short-Duration Codes

The 2026 Medicare Physician Fee Schedule maintains RPM codes 99453 and 99454 without major coverage changes and does not add new bundling restrictions for billing both codes together. Clinics can still pair device supply and management codes when they meet all requirements.

The difference between CPT code 99454 and 99457 remains clear. Code 99454 covers device supply and data transmission, while 99457 requires at least 20 minutes of clinical review and management time. New 2026 RPM codes for shorter monitoring episodes can increase revenue opportunities because clinics no longer must meet longer thresholds before billing. The 2026 RPM CPT changes introduce codes 99445 and 99470 that work alongside existing 99453 and 99454 billing.

Cardiology RPM Billing When CIED Data Is Included

In 2026, CPT 99453 for cardiology RPM is clarified as an initial service for physiologic monitoring such as heart failure or hypertension, while CPT 99454 specifies 16–30 days of monitoring for device supply and data transmission in pacemakers, ICDs, or heart failure scenarios. Traditional OEM portals create data silos that complicate billing compliance, since Medtronic, Abbott, Boston Scientific, and Biotronik systems operate independently and make tracking the 16-day requirement across devices difficult.

CPT 99453 covers initial set-up and patient education for RPM of physiologic parameters like weight and blood pressure, applicable in cardiology RPM including CIED monitoring, while CPT 99454 handles device supply with daily recordings for heart failure or hypertension patients. CPT code 99454 billing guidelines in CIED workflows require automatic data transmission from implantable devices. Rhythm360 supports this requirement through vendor-neutral integration across all major manufacturers.
