TL;DR: Aetna modified CPB 0548 — its cardiovascular home monitoring coverage policy — with an effective date of September 26, 2025. Billing teams need to review their charge capture for 17 covered CPT codes (93279, 93280, 93281, 93282, 93283, 93284, 93286, 93287, 93288, 93289, 93290, 93292, 93293, 93294, 93295, 93296, and 93297 — non-consecutive within that numeric span) and five covered HCPCS codes before claims start moving through under the updated criteria.
Aetna's CPB 0548 governs home-use cardiovascular monitoring equipment: pulse monitors, blood pressure monitors, telemonitors, and pacemaker monitors. This update touches a wide code set — from pacemaker programming codes like 93279, 93280, and 93281 to remote interrogation codes like 93294 and 93295, plus HCPCS codes A4660, A4663, A4670, E0610, and E0615 for durable medical equipment. It also adds a notable exclusion list that your billing team needs to document now.

Aetna Cardiovascular Home Monitoring Coverage Criteria and Medical Necessity Requirements 2025
The Aetna cardiovascular monitoring equipment coverage policy under CPB 0548 covers home monitoring when specific medical necessity criteria are met. The covered diagnoses anchor this entire policy — if your patient's ICD-10 code isn't on the list, the claim will not clear regardless of which CPT or HCPCS code you use.
The covered diagnosis set is specific. Aetna covers home cardiovascular monitoring equipment for patients with essential primary hypertension (I10), but not for patients under age 18. That age exclusion is explicit, and missing it will cost you.
Heart failure diagnoses (I50.1 through I50.9) are covered across the full sub-classification range. Cardiac dysrhythmias (I46.2–I49.9 and R00.1) are covered, as is the presence of a cardiac pacemaker (Z95.0). Hypertensive chronic kidney disease with stage 5 CKD or end-stage renal disease (I12.0), hypertensive heart and chronic kidney disease (I13.11–I13.2), and acute and chronic kidney disease (N17.0–N19) are also covered indications.
Patients on renal dialysis (Z99.2) are covered, which links back to why hemodialysis CPT codes 90935, 90936, and 90937 appear as related codes — those aren't reimbursed under CPB 0548 directly, but they signal a covered patient population. Hypertensive disorders in pregnancy (O10.011–O11.9 and O13.1–O16.9) and elevated blood pressure without a hypertension diagnosis (R03.0) are covered, again excluding patients under age 18.
For pacemaker monitoring specifically, CPT codes 93288 (in-person interrogation device evaluation), 93293 (transtelephonic rhythm strip evaluation), 93294 (remote interrogation, up to 90 days), and 93296 (remote data acquisition) are covered when selection criteria are met. Document the covered diagnoses listed in this policy on every claim to support medical necessity — don't assume implant history alone is sufficient.
The policy also covers programming device evaluations — CPT 93279 (single lead), 93280 (dual lead), and 93281 (multiple lead pacemaker systems) — along with defibrillator counterparts 93282, 93283, and 93284. Authorization requirements vary by Aetna plan type. Verify authorization requirements directly with Aetna before scheduling the programming evaluation, not after.
Remote interrogation for implantable cardiovascular monitors (CPT 93297, up to 30 days) and defibrillator remote interrogation (CPT 93295, up to 90 days) follow the same selection criteria. CPT 93290 — interrogation of an implantable cardiovascular monitor system, including physiologic cardiovascular data — is also covered when selection criteria are met.
For blood pressure monitoring equipment, HCPCS A4660 (sphygmomanometer with cuff and stethoscope), A4663 (blood pressure cuff only), and A4670 (automatic blood pressure monitor) are covered DME under this policy when selection criteria are met. Billing these for a patient under 18 with only R03.0 will generate a claim denial based on the explicit age exclusion.
Pacemaker monitor HCPCS codes E0610 and E0615 are covered when selection criteria are met. E0615 includes checks of battery depletion and other pacemaker components. Document that the full component check was performed to support the service described by this code.
Aetna Cardiovascular Monitoring Equipment Exclusions and Non-Covered Indications
This is the section that will generate denials if your billing team isn't current. Aetna's updated CPB 0548 draws a hard line on several newer monitoring technologies. These are not covered under any circumstances per this policy.
Bioelectrical impedance analysis (CPT 0358T) for whole-body composition assessment is explicitly not covered. If your cardiology or nephrology group has been billing 0358T alongside fluid management visits, stop and audit those claims now.
The intracardiac ischemia monitoring system codes — CPT 0525T through 0532T — are not covered. These cover insertion, replacement, and associated services for implantable ischemia monitors. This is an important exclusion if your electrophysiology group has been tracking payer coverage for these emerging systems.
External continuous pulmonary fluid monitoring (CPT 0607T and 0608T) is not covered. CPT 0607T covers remote monitoring of the system, and 0608T covers data analysis and report transmission. With pulmonary fluid monitoring gaining clinical traction in heart failure management, this exclusion is worth flagging for your cardiology medical director — and worth discussing with your compliance officer if you've been billing these codes with any frequency.
The wireless inferior vena cava sensor codes — CPT 0981T (transcatheter implantation), 0982T (remote monitoring), and 0983T (remote monitoring up to 30 days) — are not covered under CPB 0548. Same goes for CPT 0984T (intravascular optical coherence tomography of extracranial cerebral vessels) — that one is genuinely misaligned with this policy's scope, but it's listed explicitly.
Wireless pulmonary artery pressure sensor codes are not covered: CPT 33289 (transcatheter implantation) and CPT 93264 (remote monitoring of wireless PA pressure sensor, up to 30 days). HCPCS C2624 (implantable wireless pulmonary artery pressure sensor with delivery catheter) is also not covered, nor is C1833 (implantable cardiac monitor including intracardiac lead) or G0555 (replacement patient electronics system for home use).
Arterial pressure waveform analysis for central arterial pressures (CPT 93050) is not covered under this policy.
The real issue here is the pulmonary artery pressure sensor exclusions. [Editorial note: The following reflects current clinical practice trends, not CPB 0548 policy language.] Devices like CardioMEMS have seen growing adoption at many academic heart failure programs. If your cardiologists implant these devices and you've been billing 33289 or 93264 to Aetna, this policy gives you a clear signal: those claims are going nowhere. Your billing team should have a documented denial management workflow for these codes specifically.

Aetna Cardiovascular Monitoring Equipment Billing Guidelines and Action Items 2025
Home cardiovascular monitoring billing under CPB 0548 has more complexity than it appears at first pass — especially with the expanded exclusion list. Here's what your billing team should do before September 26, 2025.
| # | Action Item |
|---|---|
| 1 | Audit your active claims for excluded codes. Pull any Aetna claims with CPT 0525T–0532T, 0607T, 0608T, 0981T–0984T, 33289, 93264, or 93050 billed in 2025. Identify claims in flight before the effective date and flag them for follow-up. Any denied claims on these codes after September 26 should route to denial management, not re-billing. |
| 2 | Check age eligibility before billing I10 or R03.0. Aetna explicitly excludes patients under 18 for both essential primary hypertension (I10) and elevated blood pressure without diagnosis (R03.0). Build this check into your charge capture workflow before September 26, 2025. A single pediatric cardiology claim hitting Aetna with I10 and A4670 will deny. |
| 3 | Verify authorization requirements directly with Aetna for pacemaker programming codes 93279–93284 and 93286–93287. These are covered when selection criteria are met, but authorization requirements are not specified in CPB 0548 and vary by plan type. Check with Aetna at the individual plan level — commercial, HMO, and self-funded plans often differ. Don't assume commercial coverage mirrors Medicare rules here. |
| 4 | Document the services described when billing E0615. HCPCS E0615 covers pacemaker monitors that check battery depletion and other pacemaker components. Make sure your documentation reflects the full scope of the service billed. |
| 5 | Flag wireless PA pressure sensor programs for your compliance officer. CPT 33289 and 93264, plus HCPCS C2624, are not covered under this policy. If your heart failure program has been billing these to Aetna, get your compliance officer involved before the effective date. Continuing to bill excluded codes after September 26 creates recoupment exposure. |
| 6 | Link remote monitoring codes to the correct interrogation window. CPT 93294 covers remote interrogation up to 90 days for pacemaker systems. CPT 93295 covers the same window for ICD systems. CPT 93297 covers implantable cardiovascular monitor remote interrogation up to 30 days. Billing 93297 for a 90-day window is a reimbursement error waiting to happen — train your coders on the distinction. |
| 7 | Update your dialysis patient billing flags. Patients coded Z99.2 (dependence on renal dialysis) are a covered population. If your nephrology billing team doesn't connect home blood pressure monitoring to this diagnosis group, they may be missing covered claims. Cross-reference CPT 90935–90937 encounter records against home monitoring orders to identify those patients. |
If your organization bills both cardiology and DME, loop in your compliance officer to review how CPB 0548 billing guidelines interact with your internal policies for pacemaker monitoring and remote patient monitoring. The overlap between this policy and Aetna's telehealth and RPM policies creates gray zones that aren't resolved in CPB 0548 alone.
