TL;DR: Aetna, a CVS Health company, modified CPB 0288 covering stereotactic cingulotomy and capsulotomy, effective September 26, 2025. Here's what billing teams need to know before submitting claims under CPT 61720 and 61735.
Aetna's update to the stereotactic cingulotomy and capsulotomy coverage policy under CPB 0288 Aetna system narrows the covered indication to a single, tightly defined clinical scenario: terminal cancer pain as a last resort. If your facility or neurosurgery practice bills CPT 61720 or CPT 61735 for any other indication — psychiatric conditions, epilepsy, drug dependence — expect denial. The ICD-10-CM code list attached to this policy is broad, but the covered medical necessity criteria are not.

Aetna Stereotactic Cingulotomy Coverage Criteria and Medical Necessity Requirements 2025
The Aetna stereotactic cingulotomy coverage policy under CPB 0288 is narrow. One indication. One coverage scenario.
Aetna considers stereotactic cingulotomy medically necessary when it is used as a last resort for pain relief in members with terminal cancer pain. That's it. No other indication clears the medical necessity bar under this policy.
This matters because the attached ICD-10-CM code list runs over 130 codes. It spans schizophrenic disorders (F20.0–F21), obsessive-compulsive disorders (F42.x), mood disorders (F30–F39), anxiety disorders (F41.x), eating disorders (F50.x), drug dependence (F11.x–F16.x), Tourette's disorder (F95.2), intractable epilepsy (G40.x ranges), and specific personality disorders (F60.x). A billing team looking at that list could reasonably assume coverage extends across multiple psychiatric and neurological indications. It does not.
The real issue here is the mismatch between the ICD-10-CM code list and the covered indication. The long diagnosis code list likely reflects what Aetna's system tracks and monitors — not what Aetna will pay. If you pair CPT 61720 or CPT 61735 with a psychiatric ICD-10 code like F42.2 (OCD) or F33 (major depressive disorder) and submit without meeting the terminal cancer pain criterion, you will get a claim denial.
Prior authorization requirements are not explicitly detailed in the policy summary, but given the last-resort criterion and the high clinical specificity of this procedure, you should treat prior authorization as mandatory for any stereotactic cingulotomy billing. Call Aetna's prior auth line before scheduling. Do not assume retrospective approval is possible for a procedure this restrictive.
Reimbursement under CPT 61720 and 61735 is conditional on meeting the terminal cancer pain criteria. No documentation of last-resort status, no coverage.
Aetna Stereotactic Cingulotomy Exclusions and Non-Covered Indications
The policy is explicit: stereotactic cingulotomy for psychiatric indications is not covered. This includes — but is not limited to — OCD, depression, schizophrenia, anxiety disorders, eating disorders, and drug dependence.
Stereotactic capsulotomy follows a similar pattern. The broad ICD-10 list attached to this policy does not expand coverage. It reflects historical use cases and research contexts, not Aetna's current reimbursement criteria.
For epilepsy indications — the G40.x code ranges covering localization-related symptomatic epilepsy — coverage is not supported under the terminal cancer pain criterion. If your neurosurgery team is billing these procedures for intractable epilepsy patients, this policy does not provide a coverage path. You need a different billing strategy and potentially a different coverage policy reference for those cases.
The same applies to Tourette's disorder (F95.2) and personality disorders (F60.x). These codes appear in the ICD-10 list, but they do not meet the sole covered medical necessity criterion.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Terminal cancer pain — last resort | Covered | CPT 61720, CPT 61735 | Must document last-resort status; prior auth strongly recommended |
| OCD and anxiety disorders | Not Covered | F42.x, F41.x | ICD-10 codes in policy list but indication not covered |
| Major depressive disorder / mood disorders | Not Covered | F30–F39 | No coverage under current criteria |
| Schizophrenic disorders | Not Covered | F20.0–F21 | No coverage under current criteria |
| Drug dependence | Not Covered | F11.20–F16.21 | No coverage under current criteria |
| Eating disorders | Not Covered | F50.2–F50.9 | No coverage under current criteria |
| Specific personality disorders | Not Covered | F60.0–F60.9 | No coverage under current criteria |
| Tourette's disorder | Not Covered | F95.2 | No coverage under current criteria |
| Intractable epilepsy | Not Covered | G40.11x–G40.21x | No coverage under current criteria |
Aetna Stereotactic Cingulotomy Billing Guidelines and Action Items 2025
The effective date of September 26, 2025 is already here. If you haven't audited your claims pipeline, do it now.
| # | Action Item |
|---|---|
| 1 | Pull all claims billed with CPT 61720 or CPT 61735 since September 26, 2025. Confirm each one carries a terminal cancer diagnosis and documentation supporting last-resort status. Any claim without that clinical backing is a denial waiting to happen. |
| 2 | Check your charge capture templates. If CPT 61720 or 61735 is bundled with psychiatric ICD-10 codes in your system defaults, update those templates immediately. The mismatch between a broad ICD-10 list and a narrow covered indication is exactly where charge capture errors happen. |
| 3 | Confirm prior authorization workflows. Treat prior auth as required for every stereotactic cingulotomy or capsulotomy case billed to Aetna. The last-resort criterion means Aetna will want documentation of prior treatment failures. Gather that documentation before you submit — not after a denial. |
| 4 | Brief your neurosurgery and pain management billing staff. The 130+ ICD-10-CM codes in this policy look like a broad coverage list. They are not. Make sure your coders understand the distinction between "codes the policy references" and "codes that trigger covered reimbursement." |
| 5 | Review any pending prior authorizations for non-cancer psychiatric or neurological indications. If a case is in the queue for OCD, depression, or epilepsy, it will not clear under CPB 0288. Redirect those cases now rather than waiting for a denial at claim submission. |
| 6 | Loop in your compliance officer if you have cases where the indication is ambiguous — for example, a terminal cancer patient who also has a psychiatric comorbidity. The documentation requirements for these edge cases warrant a second set of eyes before billing. |
