Laser Neurolysis — CPB 0552 | AETNA Coverage Update

TL;DR: Aetna modified CPB 0552 for laser neurolysis, effective November 27, 2025. Every indication listed in this policy is denied as experimental — here's what your billing team needs to know before submitting claims.

Aetna's laser neurolysis coverage policy under CPB 0552 covers a wide range of neurolytic and neuroplasty CPT codes — 64600 through 64727 — but denies coverage when laser peripheral nerve block is the technique used. The policy calls out five specific indications as experimental, investigational, or unproven: carpal tunnel syndrome, complex regional pain syndrome, facet joint pain, phantom limb pain, and sacroiliac joint pain. If your practice performs laser neurolysis for any of these diagnoses and bills Aetna, you are looking at claim denial.

Aetna Laser Neurolysis Coverage Criteria and Medical Necessity Requirements 2025

The Aetna laser neurolysis coverage policy under CPB 0552 does not establish any covered pathway for laser peripheral nerve block. This is a blanket experimental designation. There are no criteria you can meet to get laser neurolysis approved for the five listed indications.

That's the real issue here. Many payer policies on nerve procedures distinguish between covered and non-covered techniques. CPB 0552 does not. Laser neurolysis billing will result in denial regardless of the patient's diagnosis, prior treatment history, or physician documentation of medical necessity.

The broader family of neurolytic CPT codes — 64600 through 64640 and 64702 through 64727 — appears in this policy as related codes. These codes cover conventional neurolysis and neuroplasty techniques. Those procedures may be covered when medical necessity criteria are met under other Aetna policies. The denial under CPB 0552 is specific to the laser technique, not the nerve procedure category as a whole.

This distinction matters for your charge capture and prior authorization workflows. If your providers use laser as the delivery method, the technique itself triggers the experimental designation — even if the CPT code you submit (say, 64640 for destruction of a peripheral nerve) could theoretically be covered under a different approach.

Aetna Laser Neurolysis Exclusions and Non-Covered Indications

Aetna considers laser peripheral nerve block experimental, investigational, or unproven for all five of the following indications. There are no exceptions listed in the policy.

Carpal tunnel syndrome — ICD-10 codes G56.0 through G56.3 cover the full laterality range. All are denied for laser neurolysis.

Complex regional pain syndrome — This covers both CRPS Type I (G90.50–G90.59) and CRPS Type II, which Aetna codes under causalgia (G56.40–G56.42 for upper limb, G57.70–G57.73 for lower limb). Any CRPS presentation billed with laser neurolysis will be denied.

Facet joint pain — Aetna references paravertebral facet joint nerve destruction in the related CPT codes (64622–64627 range). Diagnosis codes in this area include M53.82, M53.83, and M53.0 for cervicocranial syndrome.

Phantom limb pain — ICD-10 G54.6 is the relevant code. Relatively low volume in most practices, but worth flagging for practices with amputee populations.

Sacroiliac joint pain — M53.3 is the primary diagnosis code here. This one is worth watching closely. Sacroiliac joint procedures are a high-volume area in pain management, and laser-based approaches are being marketed aggressively to practices.

The policy is explicit that this is "not an all-inclusive list." That phrase is doing real work. Aetna reserves the right to deny laser neurolysis for indications beyond these five. If you're billing laser neurolysis for any nerve condition not listed here, don't assume it's covered. Check with your compliance officer before billing.
