TL;DR: Aetna, a CVS Health company, modified CPB 0237 covering chronic pain programs, effective September 26, 2025. Here's what billing teams need to know before submitting claims under this policy.
This update to the Aetna chronic pain programs coverage policy clarifies medical necessity criteria for both outpatient and inpatient multi-disciplinary pain programs, defines contraindications that will trigger denial, and explicitly lists codes that are not covered for these indications — including CPT 0117U, 96132, 96133, 96146, and remote monitoring codes 99453–99458. If your practice bills for chronic pain management services, this policy change affects your claim documentation, your prior authorization workflow, and your reimbursement on a wide range of CPT codes across psychiatry, psychology, neurostimulation, and health behavior intervention.

Aetna Chronic Pain Program Coverage Criteria and Medical Necessity Requirements 2025
CPB 0237 Aetna lays out a strict, multi-gate approval structure for chronic pain programs. There are separate criteria for outpatient programs, inpatient programs, and screening exams. Each gate must be cleared before Aetna will consider a service medically necessary.
Screening exams are the simplest piece. Aetna considers a screening examination medically necessary for members being evaluated for admission into a chronic pain program. Bill this appropriately — it's a covered service, and it's your first documentation anchor.
Outpatient multi-disciplinary pain management programs require all seven of the following to be true before Aetna considers entry medically necessary:
| # | Covered Indication |
|---|---|
| 1 | Any indicated surgical procedure or acute medical treatment has already been completed |
| 2 | The member has experienced chronic non-malignant pain for six months or more (cancer pain is explicitly excluded) |
| 3 | The member has failed conventional treatment methods |
| 4 | The member has completed a mental health evaluation, and any primary psychiatric conditions have been treated |
| 5 | The member's work or lifestyle has been significantly impaired by chronic pain |
| 6 | The referring physician — primary care or attending — has made a formal referral |
| 7 | The cause of pain is unknown or attributable to a physical cause (not purely psychogenic) |
Every single criterion must be documented. Miss one, and you're looking at a claim denial. This is not a situation where "close enough" works.
Aetna defines chronic pain as pain from a chronic pathological process, recurring periodically over months or years, or persisting longer than expected after illness or injury. The standard threshold is six months or more.
One addition in this policy that billing teams sometimes miss: substance use. Aetna states that moderate to severe substance use disorders require detoxification to be considered and evaluated before enrollment. If your patient has a substance use disorder and enters the program without this step documented, your claim is at risk. A referral to an Addiction Medicine specialist should be in the chart.
Inpatient multi-disciplinary pain programs carry all the outpatient criteria plus four more:
| # | Covered Indication |
|---|---|
| 1 | The member has major functional disabilities |
| 2 | The member needs extensive psychological or behavioral therapy |
| 3 | The member needs temporary removal from a detrimental home environment to refocus away from pain |
| 4 | The pain has caused extensive disruption in family functioning |
Inpatient coverage is limited to 21 days. Any stay beyond 21 days requires medical necessity review. Pre-admission evaluations — medical and psychological — must be done on an outpatient basis. Admitting someone for those evaluations alone is not medically necessary under this coverage policy.
Prior authorization requirements for chronic pain programs are not explicitly detailed in this CPB. Check with your Aetna provider relations contact or your plan-specific documentation for prior auth requirements before scheduling admissions.
Aetna Chronic Pain Program Exclusions and Non-Covered Indications
Several contraindications make entry into an outpatient multi-disciplinary chronic pain program not medically necessary. If any of these apply, Aetna will not cover program enrollment — period.
The contraindications are:
| # | Excluded Procedure |
|---|---|
| 1 | Aggressive or violent behavior |
| 2 | Imminent suicidal tendencies |
| 3 | Prior failure of an adequate multi-disciplinary (e.g., CARF-accredited) chronic pain program |
| 4 | Unrealistic expectations (expecting an immediate cure) |
| 5 | Medical instability — including uncontrollable high blood pressure, unstable congestive heart failure, or similar conditions |
| 6 | Inability to understand and carry out instructions |
The third contraindication deserves attention. If a member has already failed a CARF-accredited chronic pain program, they cannot get into another one under this policy. That's a hard stop for reimbursement. Make sure your intake team is screening for prior program history before scheduling.
Inpatient programs have their own non-covered scenarios. Admission for pre-program evaluations alone is not covered — those must happen outpatient. Continued inpatient treatment is not medically necessary if the patient is not participating in scheduled sessions. And a patient who previously failed an adequate inpatient program is not eligible for another admission under this coverage policy.
The policy also explicitly excludes several CPT codes for indications covered under CPB 0237. CPT 0117U (pain management analysis of 11 endogenous analytes), 96132 and 96133 (neuropsychological testing evaluation services), 96146 (psychological or neuropsychological test administration with single automated instrument), and the remote monitoring codes 99453, 99454, 99457, and 99458 are all listed as not covered for indications in this CPB.
If your team has been billing any of these remote physiologic monitoring codes alongside chronic pain program services for Aetna members, stop. That's a denial waiting to happen under this updated policy.

Aetna Chronic Pain Program Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit your intake documentation before September 26, 2025. All seven outpatient medical necessity criteria must be clearly documented in the chart before program enrollment. Build a documentation checklist that maps directly to Aetna's seven criteria. Missing even one is a denial trigger. |
| 2 | Remove CPT 99453, 99454, 99457, and 99458 from your chronic pain program charge capture for Aetna members. These remote physiologic monitoring codes are explicitly not covered for CPB 0237 indications. If your EHR has these codes bundled into chronic pain program order sets, your billing team needs to pull them out now. |
| 3 | Flag CPT 96132, 96133, and 96146 in your Aetna charge capture. Neuropsychological testing and automated psychological testing are not covered under this policy. If these tests are part of your standard pain program intake, bill them separately and confirm they fall under a different coverage policy — or don't bill them to Aetna at all for these patients. |
| 4 | Document substance use disorder screening and referral for every admission. If a member has moderate to severe substance use disorder, your chart needs to show that detoxification was considered and evaluated, and that an Addiction Medicine referral was made. This is a clinical and billing requirement under CPB 0237. |
| 5 | Confirm prior program history during intake. If a member previously completed and failed a CARF-accredited chronic pain program, they are not eligible under this policy. Catching this at intake saves you the cost of a claim denial and a potential appeals cycle. |
| 6 | For inpatient admissions, confirm pre-admission evaluations happened outpatient. Admitting a patient to complete psychological or medical evaluations before the pain program starts is not covered. The chart must show these evaluations were completed before the inpatient admission date. |
| 7 | Review your chronic pain program billing guidelines for Aetna against the full CPB 0237 text. The policy summary above is detailed, but the full document covers additional nuance around inpatient limitations and partial hospitalization. If you manage a high volume of Aetna chronic pain cases, loop in your compliance officer before the effective date to review how your current documentation practices stack up. |
