Aetna modified CPB 0332 for neonatal hyperbilirubinemia, effective September 26, 2025. Here's what billing teams need to do.
Aetna, a CVS Health company, updated Clinical Policy Bulletin CPB 0332 covering newborn jaundice and related conditions. This revision touches 16 CPT codes and four HCPCS codes — including phototherapy (E0202, S9098), exchange transfusion (CPT 36450), bilirubin testing (82247, 82248), and G6PD screening (82955, 82960). If your team bills for neonatal care, NICU services, or home phototherapy, review your charge capture and documentation workflows before September 26, 2025.

Aetna Neonatal Hyperbilirubinemia Coverage Criteria and Medical Necessity Requirements 2025
The Aetna neonatal hyperbilirubinemia coverage policy ties reimbursement to documented medical necessity at the code level. Aetna considers interventions medically necessary when specific criteria are met — and that "when criteria are met" language is doing a lot of work here.
For the core diagnostic and treatment codes, coverage is conditional. CPT 82247 (bilirubin, total) and CPT 82248 (bilirubin, direct) are covered when clinical criteria support testing. CPT 82955 and 82960 — G6PD quantitative and screen — are covered under the same framework. Exchange transfusion under CPT 36450 and phototherapy equipment under HCPCS E0202 are covered when selection criteria are satisfied.
Home phototherapy (S9098) falls under covered HCPCS codes, but expect scrutiny. Home-based services for bilirubin management are a frequent target for claim denial when documentation doesn't specifically reflect the medical necessity threshold that triggered the transition from inpatient to home care. Get that documentation tight before you bill.
The Aetna neonatal hyperbilirubinemia coverage policy also brings G6PD gene analysis into scope. CPT codes 81247, 81248, and 81249 appear as "other CPT codes related to the CPB," which means they're relevant but don't carry the same covered-when-criteria-are-met designation as the primary codes. Treat these as watch-list codes for prior authorization.
Two molecular pathology codes — CPT 81328 (SLCO1B1) and CPT 81350 (UGT1A1) — are explicitly grouped under experimental or non-covered designations tied to genotyping of BLVRA and deep learning-based prediction methods. If someone on your team is billing these for neonatal jaundice risk prediction, stop and re-read the policy. Those claims will not survive.
Aetna Neonatal Hyperbilirubinemia Exclusions and Non-Covered Indications
This is where the policy gets specific — and where denials will cluster if your team isn't paying attention.
CPT 81328 and CPT 81350 land in a non-covered grouping labeled "Genotyping of BLVRA, Deep learning-based method for predicting." These are not experimental-pending-evidence designations. Aetna treats them as outside the covered framework for this condition. The same grouping includes CPT 81400 (molecular pathology, Level 1) and CPT 97124 (massage therapy). Massage for neonatal hyperbilirubinemia as a covered intervention — that's a real question some practices have pursued. Aetna says no here.
Phenobarbital has a specific carve-out. HCPCS J2560 and J2561 (phenobarbital sodium injections) appear in a group labeled "Prebiotics, Ursodeoxycholic acid — no specific code." That grouping language is telling you these agents don't have a direct covered pathway in CPB 0332. The ICD-10 block O36.1110–O36.1999 for maternal isoimmunization is specifically noted as not covered for antenatal phenobarbital use in red cell alloimmunization. If your maternal-fetal medicine team is billing phenobarbital for isoimmunization prevention, flag that for your compliance officer now.
The intravenous infusion codes — CPT 96365, 96366, 96367, and 96368 — sit in the "other CPT codes related to the CPB" group. They're not explicitly covered or excluded, but they're not in the primary covered group either. These will need strong supporting documentation and a clear medical necessity argument to survive review.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Bilirubin testing — total and direct | Covered (criteria-dependent) | CPT 82247, 82248 | Document clinical indication clearly |
| G6PD screening and quantitative testing | Covered (criteria-dependent) | CPT 82955, 82960 | Covered when selection criteria met |
| Exchange transfusion in newborn | Covered (criteria-dependent) | CPT 36450 | High-acuity; document threshold bilirubin levels |
| Phototherapy (inpatient/outpatient equipment) | Covered (criteria-dependent) | HCPCS E0202 | Requires medical necessity documentation |
| Home phototherapy services | Covered (criteria-dependent) | HCPCS S9098 | High denial risk without robust discharge documentation |
| G6PD gene analysis | Related codes — coverage conditional | CPT 81247, 81248, 81249 | Not in primary covered group; prior authorization likely |
| G6PD genetic susceptibility / family history | Diagnosis codes recognized | ICD-10 Z15.89, Z83.49, Z84.81 | Use for appropriate family history and susceptibility coding |
| SLCO1B1 / UGT1A1 genotyping | Not covered | CPT 81328, 81350 | Experimental grouping — do not bill for this indication |

Aetna Neonatal Hyperbilirubinemia Billing Guidelines and Action Items 2025
The CPB 0332 Aetna system update takes effect September 26, 2025. Here's what your billing team needs to do now.
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for the core covered codes before September 26, 2025. Pull claims from the last 90 days for CPT 36450, 82247, 82248, 82955, and 82960. Confirm each claim has documentation that directly maps to the "selection criteria" language in the policy. Vague clinical notes won't hold up on redetermination. |
| 2 | Flag CPT 81328, 81350, 81400, and 97124 in your billing system. These codes are in a non-covered grouping for this diagnosis. Set a hard stop or alert so your team doesn't accidentally submit them against P55–P59 or related ICD-10 diagnosis codes. A single incorrect attachment of these codes to a neonatal jaundice claim will generate a denial that takes weeks to resolve. |
| 3 | Review all home phototherapy claims under S9098. This is your highest-risk code in this policy. Aetna covers it, but home-based neonatal hyperbilirubinemia billing draws scrutiny. Your documentation needs to show the bilirubin level at discharge, why home phototherapy was clinically appropriate instead of continued inpatient care, and what monitoring protocol was put in place. If you can't find that in the chart, the claim shouldn't go out. |
| 4 | Check prior authorization workflows for G6PD gene analysis codes (81247, 81248, 81249). These sit in a gray zone in CPB 0332. They're listed as "other CPT codes related to the CPB" — not in the primary covered group. Before billing these for neonatal patients, confirm prior authorization is in place. If your team has been billing these without checking auth status, pull a claims sample and assess exposure. |
| 5 | Update diagnosis coding workflows to use the correct ICD-10 range. P55.0–P55.9 (hemolytic disease of newborn), P57.0–P57.9 (kernicterus), P58.0–P58.9 (neonatal jaundice due to excessive hemolysis), and P59.0–P59.9 (neonatal jaundice, other and unspecified causes) are all recognized in CPB 0332. Be specific. Don't default to P59.9 when the chart supports a more specific code — that habit leads to medical necessity denials when Aetna cross-checks diagnosis against procedure. |
| 6 | Alert your maternal-fetal medicine billing team about the O36.1110–O36.1999 exclusion. Antenatal phenobarbital for red cell alloimmunization is explicitly not covered under this policy when billed against that ICD-10 range. If your MFM team has been billing J2560 or J2561 against those maternal codes, that exposure needs a compliance review. Talk to your compliance officer before the effective date of September 26, 2025. |
