Aetna modified CPB 1010 for the Dengvaxia dengue vaccine, effective February 27, 2026. Here's what billing teams need to know before submitting claims.
Aetna, a CVS Health company, updated Clinical Policy Bulletin CPB 1010 to define medical necessity criteria for dengue tetravalent vaccine (Dengvaxia). The policy covers CPT codes 90584 and 90587 — the two-dose and three-dose Dengvaxia schedules — under strict eligibility requirements. If your practice administers Dengvaxia to Aetna members, the coverage criteria in this update directly determine whether your claims pay or deny.

Aetna Dengue Vaccine Coverage Criteria and Medical Necessity Requirements 2026
The Aetna dengue vaccine coverage policy is narrow. Aetna covers Dengvaxia only when three conditions are all true: the patient is between 9 and 16 years old, the patient lives in a dengue-endemic area, and the patient has laboratory-confirmed previous dengue infection.
All three boxes must be checked. Miss one, and the claim will likely deny.
Medical necessity under this coverage policy hinges on documented prior infection. Aetna accepts two forms of proof: a medical record showing a previous laboratory-confirmed dengue infection, or serological testing conducted before vaccination. If your practice is performing pre-vaccination serology, bill that encounter separately and retain the results in the patient's chart. You will need that documentation to support any prior authorization request or appeal.
The real issue here is the serology requirement. Without it, you cannot establish medical necessity for Aetna. If a patient presents for Dengvaxia vaccination but has no documented prior infection, stop — do not administer and bill. The claim will not pay, and the clinical guidance is clear: unconfirmed or dengue-naive patients face higher risk of severe disease if vaccinated.
Dengue vaccine billing under CPB 1010 in the CPB 1010 Aetna system covers CPT 90584 (two-dose schedule) and CPT 90587 (three-dose schedule). Both codes fall under "CPT codes covered if selection criteria are met." Administer the vaccine before confirming all criteria, and you're creating a medical necessity problem that documentation alone cannot fix after the fact.
Prior authorization requirements are not explicitly listed in CPB 1010, but Aetna frequently requires prior auth for vaccines with narrow eligibility windows. Check your specific plan contract and confirm requirements before the first dose. Given the age restriction, endemic-area requirement, and the serology threshold, this is exactly the type of policy where a prior auth step protects your reimbursement.
Aetna Dengue Vaccine Exclusions and Non-Covered Indications
Aetna excludes two groups from Dengvaxia coverage, and both exclusions are firm.
The first exclusion: individuals not previously infected by any dengue virus serotype. Aetna states explicitly that Dengvaxia is not medically necessary for dengue-naive patients. This isn't a soft exclusion. Aetna cites the clinical risk directly — vaccinating a dengue-naive person increases their risk of severe dengue if they subsequently contract the virus. Claims for this group will be denied, and there's no appeals pathway that changes the underlying biology.
The second exclusion: travelers. Aetna classifies Dengvaxia as experimental, investigational, or unproven for individuals living in non-endemic areas who travel to dengue-endemic areas. The policy states that "safety and effectiveness for this indication has not been established." Travel medicine practices billing Dengvaxia for U.S.-based travelers heading to endemic destinations should stop and reassess their billing workflows. This is not a covered indication under Aetna's 2026 coverage policy, and billing CPT 90584 or 90587 for travelers will generate claim denials.
If your patient population includes international travelers receiving Dengvaxia, talk to your compliance officer before the effective date of February 27, 2026 to assess your exposure.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Ages 9–16, laboratory-confirmed prior dengue infection, living in endemic area | Covered | CPT 90584, CPT 90587, A90, A91, Z86.19 | All three criteria required; prior infection documented via medical record or serology |
| Dengue-naive individuals (no prior infection or unknown status) | Not Covered | CPT 90584, CPT 90587 | Aetna cites increased risk of severe dengue; medical necessity denied |
| Travelers living in non-endemic areas traveling to endemic areas | Experimental / Investigational | CPT 90584, CPT 90587 | Safety and effectiveness not established for this indication |
Aetna Dengue Vaccine Billing Guidelines and Action Items 2026
| # | Action Item |
|---|---|
| 1 | Audit your patient files before February 27, 2026. Pull any Aetna members scheduled for Dengvaxia. Confirm each one has a laboratory-confirmed prior dengue infection on record. If the documentation isn't there, do not schedule the administration until serology is completed and results are in the chart. |
| 2 | Update your charge capture for CPT 90584 and CPT 90587. Add a documentation checkpoint that requires confirmation of prior infection, endemic-area residency, and patient age (9–16) before either code is released to billing. Hard stops in your EHR or charge capture workflow prevent claim denials downstream. |
| 3 | Verify prior authorization requirements with each Aetna plan before the first dose. CPB 1010 sets the medical necessity standard, but individual plan contracts determine prior auth workflows. Call or check the Aetna provider portal for your specific plans. Get prior auth before administration — not after. |
| 4 | Bill immunization administration codes correctly alongside the vaccine. If the patient is 18 or under, use CPT 90460 for immunization administration with counseling. Add CPT +90461 for each additional vaccine component. If counseling exceeds certain time thresholds, 90482, 90483, and 90484 apply for physician counseling time. HCPCS codes G0310 through G0313 also cover immunization counseling in this context — confirm which codes your specific Aetna plan contract accepts. |
| 5 | Document endemic-area residency in the medical record. "Living in an endemic area" is a coverage criterion, not just a clinical footnote. The patient's address and any supporting documentation of residency in an endemic region should appear in the encounter notes. A claim denial for lack of medical necessity is much harder to overturn without this in the chart. |
| 6 | Flag travel medicine patients for compliance review immediately. If your practice has been billing Dengvaxia for travelers under Aetna, that's now explicitly experimental under this coverage policy. Review open claims, assess denial exposure, and loop in your compliance officer. The effective date is February 27, 2026 — that's your deadline to get your house in order. |
| 7 | Cross-reference ICD-10 coding against the covered indication. Use A90 (dengue fever) or A91 (dengue hemorrhagic fever) for active or previous dengue disease history, and Z86.19 (personal history of other infectious and parasitic diseases) to document prior dengue infection. Z86.19 is your most important supporting diagnosis code — it communicates prior infection history directly and cleanly. Pair it with the vaccine CPT codes on every covered claim. |
