Aetna modified CPB 0431 for primary nocturnal enuresis, effective September 26, 2025. Here's what billing teams need to know about coverage criteria, HCPCS S8270, J2597, and the codes Aetna will not cover.
Aetna, a CVS Health company, updated its enuresis coverage policy under CPB 0431 in the CPB 0431 Aetna system. The policy governs bedwetting alarm billing under HCPCS S8270 and desmopressin reimbursement under J2597, plus a long list of interventions the payer considers experimental or not covered. If your practice manages pediatric urology, primary care, or DME billing for bedwetting treatment, this policy directly affects your claim outcomes.

Aetna Enuresis Coverage Criteria and Medical Necessity Requirements 2025
The Aetna enuresis coverage policy covers two interventions under CPB 0431: the bedwetting alarm as durable medical equipment and desmopressin. Both have distinct medical necessity criteria, and both can be denied if documentation gaps exist.
Bedwetting Alarm (HCPCS S8270)
Aetna covers the enuresis alarm under HCPCS S8270 as DME when all four of the following criteria are met:
| # | Covered Indication |
|---|---|
| 1 | The member is 7 years of age or older. |
| 2 | The member has wet the bed at least three nights a week in the previous month, or has had at least one wetting episode weekly for one year. |
| 3 | The member has no daytime wetting. |
| 4 | A physician has examined the member and ruled out physical or organic causes — including renal disease, neurological disease, and infection. |
All four criteria must be documented. Miss one, and Aetna treats the claim as experimental. The ICD-10 diagnosis code to pair with S8270 is N39.44 (nocturnal enuresis). Make sure your providers are using N39.44, not a general enuresis code that doesn't specify nocturnal onset.
One detail worth flagging to your DME billing team: Aetna explicitly states that special training or skilled monitoring services to support alarm use are not generally considered medically necessary. Don't bill for nursing instruction or behavioral coaching tied to the alarm and expect coverage. That's a claim denial waiting to happen.
Desmopressin (HCPCS J2597)
For desmopressin — billed as J2597 (injection, desmopressin acetate, per 1 mcg) — the coverage policy requires the member to be older than five years. Prior treatment with non-pharmacologic therapies like fluid intake advice or enuresis alarm treatment must have failed. Alternatively, the member must have refused alarm treatment or be unlikely to adhere to it.
That "unlikely to adhere" language is vague, and Aetna doesn't define it further in this policy. Document the clinical rationale in the chart. Your prior authorization request should spell out which non-pharmacologic therapies were tried and when, or why alarm treatment isn't viable for this patient.
Aetna Enuresis Exclusions and Non-Covered Indications
This is where the policy gets interesting — and where your claim exposure is highest.
Aetna classifies a significant number of enuresis treatments as experimental, investigational, or unproven. The covered interventions are narrow. Everything outside S8270 and J2597 faces a hard wall.
Specifically, Aetna does not cover the following for enuresis treatment:
| # | Excluded Procedure |
|---|---|
| 1 | Acupuncture (CPT 97810, 97811, 97812, 97813, 97814) — grouped as not covered |
| 2 | Hypnotherapy (CPT 90880) — grouped as not covered |
| 3 | Chiropractic manipulative treatment (CPT 98940, 98941, 98942, 98943) — grouped as not covered |
| 4 | Therapeutic massage (CPT 97124) — grouped as not covered |
| 5 | TENS devices (HCPCS E0720, E0730) — grouped under laser acupuncture, also not covered |
| 6 | Clonidine (HCPCS J0735) — not covered for enuresis |
| 7 | Tonsillectomy and adenoidectomy (CPT 42820, 42821, 42825, 42826, 42830, 42831, 42835, 42836) — not covered for enuresis treatment specifically |
| 8 | Bladder training (urotherapy) and magnetic sacral root stimulation — not covered, per the group labels associated with the CPT codes above |
The T&A codes (42820–42836) showing up here is notable. Some providers attempt to connect sleep-disordered breathing, T&A surgery, and secondary enuresis resolution. Aetna is not buying that linkage for reimbursement under this policy. If a child's bedwetting resolves after T&A, that's a clinical outcome — not a covered indication under CPB 0431.
If your practice bills any of these services for pediatric enuresis patients, pull those claims now. Check what diagnosis codes are attached. A claim billed with N39.44 alongside CPT 97810 will not pass Aetna's coverage policy.

Aetna Enuresis Billing Guidelines and Action Items 2025
The effective date of September 26, 2025 has already passed. If your team hasn't reviewed charge capture for enuresis-related claims, do it now.
| # | Action Item |
|---|---|
| 1 | Audit your S8270 claims back to September 26, 2025. Pull any claims billed with S8270 and N39.44. Confirm that all four medical necessity criteria are present in the documentation — age 7+, frequency threshold, no daytime wetting, and physician workup. Any claim missing documentation is a denial risk. |
| 2 | Check J2597 claims for non-pharm treatment history. For desmopressin billing under J2597, your chart documentation must show that fluid intake advice and/or alarm treatment was tried, failed, or refused. A J2597 claim without that history will not survive Aetna's review. |
| 3 | Remove N39.44 from charge capture triggers for non-covered CPT codes. If your charge capture system auto-populates enuresis codes, make sure CPT codes like 97810 (acupuncture), 90880 (hypnotherapy), and 98940–98943 (chiropractic) cannot fire with N39.44 as the primary diagnosis. That combination produces an automatic denial under this coverage policy. |
| 4 | Do not bill training or monitoring services alongside S8270. Aetna's billing guidelines are explicit: skilled care and monitoring to support alarm use are not medically necessary. Don't attach a nursing visit or behavioral health code to an S8270 claim for this purpose. |
| 5 | Flag T&A claims where enuresis is listed as a secondary or related diagnosis. CPT codes 42820, 42821, 42825, 42826, 42830, 42831, 42835, and 42836 are listed in this policy as not covered for enuresis treatment. If your coding team is using N39.44 as a supporting diagnosis on T&A claims, remove it. It adds no coverage benefit here and can trigger review. |
| 6 | Confirm prior authorization requirements with Aetna for J2597. The policy doesn't spell out prior auth requirements explicitly, but desmopressin for pediatric patients often requires prior authorization under commercial plans. Check the member's specific plan before submitting. If you're unsure how this applies to your patient mix, loop in your billing consultant before the claim goes out. |
