TL;DR: Aetna, a CVS Health company, modified CPB 0829 for intra-vascular optical coherence tomography (OCT), effective December 5, 2025. Every indication is non-covered — and your team needs to know exactly which codes to expect denials on.
Aetna's intra-vascular OCT coverage policy under CPB 0829 Aetna system classifies this technology as experimental, investigational, or unproven across the board. That means CPT codes 92978, 92979, and the newer Category III codes 0984T through 0987T all land in denial territory. If your cardiology or vascular team bills OCT-guided procedures, this update deserves your attention before December 5, 2025.

Aetna Intra-Vascular OCT Coverage Criteria and Medical Necessity Requirements 2025
Here's the blunt version of this coverage policy: there are no covered indications. Aetna does not recognize medical necessity for intra-vascular OCT under any clinical scenario. This is a complete exclusion policy, not a narrowed-criteria policy.
The Aetna intra-vascular OCT billing situation is different from a policy where you meet criteria and get paid. There is no criteria to meet. Aetna's position is that the evidence base for this technology is insufficient — full stop.
This affects prior authorization workflows too. Don't waste time submitting prior auth requests hoping for approval. Aetna will not authorize intra-vascular OCT because the procedure doesn't meet medical necessity under this policy. If a physician in your group is ordering OCT guidance for coronary stent placement and expecting reimbursement, that expectation needs to be corrected now.
The primary codes caught by this denial wall are CPT 92978 (endoluminal imaging of coronary vessel or graft using intravascular ultrasound or optical coherence tomography, initial vessel) and CPT 92979 (each additional vessel). The Category III codes — 0984T, 0985T, 0986T, and 0987T — cover OCT of cerebral vessels and also carry non-covered status. None of these generate reimbursement from Aetna.
Aetna Intra-Vascular OCT Exclusions and Non-Covered Indications
The exclusion list in CPB 0829 is long. Aetna explicitly calls out 19 separate indications — each one denied as experimental, investigational, or unproven. That list covers the major clinical scenarios your interventional cardiologists, neurologists, and pulmonologists use to justify OCT.
This isn't a case of vague policy language. Aetna names each indication individually. That specificity makes claim denial more likely when any of these diagnosis codes appear on an OCT claim.
The 19 non-covered indications under CPB 0829 are:
| # | Excluded Procedure |
|---|---|
| 1 | Assessment of acute coronary syndrome |
| 2 | Assessment of carotid artery stenosis and stroke risk |
| 3 | Assessment of pulmonary arterial wall fibrosis as a prognostic marker of pulmonary arterial hypertension |
| 4 | Assessment of severity of coronary artery lesion (vulnerable plaque identification and risk stratification) |
| 5 | Detection of cardiac allograft vasculopathy following heart transplantation |
| 6 | Diagnosis and rupture assessment of intracranial aneurysm |
| 7 | Diagnosis of pulmonary artery thrombus |
| 8 | Evaluation of arterial bifurcations covered by flow-diverting stents |
| 9 | Evaluation of coronary stenosis in individuals with antiphospholipid syndrome (ICD-10 D68.61) |
| 10 | Evaluation of pulmonary arterial vasculopathy in systemic sclerosis |
| 11 | Evaluation of pulmonary vascular structures in individuals with congenital heart disease |
| 12 | Guidance for percutaneous coronary intervention in STEMI patients (ICD-10 I21.x) |
| 13 | Guidance of intra-coronary stenting and post-stent follow-up |
| 14 | Guidance of percutaneous treatment of coronary bifurcation disease |
| 15 | Follow-up evaluation of renal arteries after radiofrequency catheter-based renal denervation |
| 16 | Imaging of cerebral vessels |
| 17 | Prediction of periprocedural myocardial injury in stable angina (ICD-10 I20.x) |
| 18 | Treatment as an adjunct to percutaneous coronary interventions |
| 19 | Use during percutaneous coronary intervention with orbital atherectomy |
If your team sees any of the above as a documented clinical rationale on an OCT order, expect a denial. There is no appeal path based on medical necessity under this policy — Aetna's position is that the evidence simply isn't there yet.

Aetna Intra-Vascular OCT Billing Guidelines and Action Items 2025
The billing guidelines here are clear in one direction: stop billing these codes expecting payment from Aetna. Here's what your team should do before December 5, 2025.
| # | Action Item |
|---|---|
| 1 | Flag CPT 92978, 92979, 0984T, 0985T, 0986T, and 0987T as non-covered in your charge capture system. Add a hard stop or warning that fires when any of these codes appear with an Aetna payer. Do this before the December 5, 2025 effective date. |
| 2 | Audit claims already in the queue. Pull any pending or recently submitted claims for CPT 92978 or 92979 with Aetna as the payer. If they haven't been adjudicated yet, prepare for denials. Get your appeal documentation ready now — though know that medical necessity appeals won't reverse this policy. |
| 3 | Update your ABN (Advance Beneficiary Notice) or financial responsibility process for Aetna commercial patients. Since no medical necessity pathway exists, patients need to be informed of financial responsibility before OCT procedures are performed. Work with your front-end team and your compliance officer to build that workflow. |
| 4 | Alert your interventional cardiology and vascular teams directly. The STEMI guidance indication (ICD-10 I21.x codes) is particularly high-stakes. OCT-guided PCI in STEMI is a scenario where physicians move fast and billing happens later. Make sure the clinical team knows Aetna won't pay — and that the revenue cycle team doesn't get stuck holding the bag on uncollectable claims. |
| 5 | Check the related policies: CPB 0382 (Intravascular Ultrasound) and CPB 0520 (Cardiac MRI). If your team has been using intra-vascular OCT and is now looking for a covered alternative, IVUS under CPB 0382 may have different coverage criteria. Review before assuming IVUS is a direct covered substitute — but it's worth checking with your compliance officer. |
| 6 | Don't submit prior authorization requests for non-covered OCT procedures. Prior auth requests for experimental or unproven procedures under Aetna create administrative burden with no upside. Remove any OCT codes from your standard prior auth submission workflows for Aetna patients. |
If you're unsure how this policy interacts with your specific Aetna contract or plan mix, talk to your compliance officer before December 5, 2025. Commercial plan terms can vary, and what applies to the CPB may interact differently with specific employer plan exclusions.
