Pudendal Nerve Decompression — CPB 0805 | AETNA Coverage Update

Aetna modified CPB 0805 governing pudendal nerve decompression, effective November 22, 2025. Every procedure under this policy — CPT 64430, 64630, and 64722 — is classified as experimental. Here's what your billing team needs to know.

Aetna, a CVS Health company, updated Clinical Policy Bulletin CPB 0805 to address pudendal nerve decompression and related procedures. The policy draws a hard line: no covered indications. Pudendal nerve decompression, nerve blocks for neuritis, hydrodissection, and neurolysis are all experimental, investigational, or unproven across every listed diagnosis. If your practice bills these procedures for Aetna members — whether for chronic pelvic pain, pudendal neuralgia, vulvodynia, or erectile dysfunction — expect claim denial.

Aetna Pudendal Nerve Decompression Coverage Criteria and Medical Necessity Requirements 2025

The short answer: there are none. Aetna's coverage policy under CPB 0805 does not establish any covered pathway for pudendal nerve decompression procedures. There is no set of medical necessity criteria your team can meet to get these procedures reimbursed through Aetna.

This is the core of the Aetna pudendal nerve decompression coverage policy — every procedure in scope is denied on experimental grounds, regardless of diagnosis. Medical necessity documentation won't change the outcome. Aetna's position is that the clinical evidence is insufficient to support coverage, full stop.

Prior authorization is effectively moot here. When a payer classifies a procedure as experimental or investigational, prior authorization processes don't apply in the way they do for covered services. You won't get a prior auth approved for a service Aetna has already decided it won't pay for. If a provider on your team is performing these procedures for Aetna members, the financial exposure falls on the practice or the patient — not on a missing authorization.

The one exception worth noting: pudendal nerve blocks used in obstetrics and other operative procedures are carved out of this policy. That means CPT 64430 billed in an OB or surgical context operates under different coverage rules. Make sure your billers understand that distinction before assuming all 64430 claims are non-covered.

Aetna Pudendal Nerve Procedures: Exclusions and Non-Covered Indications 2025

This entire policy is an exclusions list. That's what makes it unusual. Most Clinical Policy Bulletins define who qualifies for coverage. CPB 0805 defines who doesn't — and that's everyone.

Here's what Aetna explicitly classifies as experimental, investigational, or unproven under the November 22, 2025 policy update:

Pudendal nerve decompression is not covered for any of the following diagnoses:

Pudendal nerve block for pudendal neuritis is not covered. Again — this exclusion does not apply to obstetric use or blocks performed as part of other operative procedures.

Pudendal nerve hydrodissection is not covered for chronic pelvic pain syndrome or urinary incontinence.

Pudendal neurolysis is not covered for persistent genital arousal disorder or pudendal nerve entrapment syndrome.

The real issue here is scope creep risk. Providers treating these conditions may attempt to bill CPT 64722 (decompression, unspecified nerve) with a related ICD-10 code and assume it will pass. With 156 ICD-10-CM codes listed in this policy — many of them G57.x mononeuropathy codes — Aetna has clearly anticipated that pattern. Those codes are flagged. Claims will deny.

CPT, HCPCS, and ICD-10 Codes for Pudendal Nerve Procedures Under CPB 0805

CPT Codes Listed in CPB 0805

All three CPT codes under this policy are mapped to experimental/non-covered procedures. There are no covered CPT codes in CPB 0805.

Code	Type	Description	Context in Policy Copy
64430	CPT	Injection, anesthetic agent; pudendal nerve	Used for nerve block (neuritis — not covered) and as closest available code for hydrodissection
64630	CPT	Destruction by neurolytic agent; pudendal nerve	Used for pudendal neurolysis — not covered
64722	CPT	Decompression, unspecified nerve(s) (specify)	Used for pudendal nerve decompression — not covered

Note: Aetna flags that there is no procedure-specific CPT code for pudendal nerve hydrodissection. CPT 64430 is the closest available code for that service — but the service itself is non-covered under this policy.

Key ICD-10-CM Diagnosis Codes Listed in CPB 0805

The policy includes 156 ICD-10-CM codes. Below is the full set from the policy data. These codes appear in the context of non-covered indications — pairing them with the CPT codes above will generate a denial for Aetna members.

The full policy includes 156 ICD-10-CM codes. The remaining codes beyond G57.76 continue in the G57.x mononeuropathy range. Review the complete list at the CPB 0805 Aetna source policy before finalizing your denial edits.
