Monitor payer policy activity
This policy governs coverage and medical necessity determinations for FDA-approved rotavirus vaccines (RotaTeq and Rotarix) for prevention of rotavirus gastroenteritis in infants, and applies to Aetna plan adjudication (check specific member benefit plans for preventive service exclusions).
No material clinical or coverage changes in this revision.
Coverage and Medical Necessity Criteria
Medical Necessity
Covered when ALL of the following are met:
Policy bases coverage on FDA-approved vaccines and ACIP recommendations.
Experimental and Investigational
Policy explicitly restricts coverage to the listed indication.
Some Aetna member benefit plans include exclusions for preventive services. Because rotavirus vaccination is provided as a preventive service for infants, coverage may be limited or excluded depending on the member’s specific plan. Verify the member’s benefit plan description and coverage details before administering or billing for rotavirus vaccine.
This Clinical Policy Bulletin is provided to assist in administering plan benefits but does not constitute an offer of coverage or medical advice. It contains a partial, general description of plan or program benefits and is not a contract; treating providers remain responsible for medical advice and treatment, and the bulletin may be updated or changed.
Use of rotavirus vaccine for indications other than the prevention of rotavirus gastroenteritis in infants younger than 8 months of age is considered experimental, investigational, and not medically necessary under this policy because effectiveness for other indications has not been established. Do not bill for administration outside the covered infant indication without confirming medical necessity and plan coverage.

Provider Actions, Authorization, and Documentation
Prior Authorization
Prior authorization: No explicit prior authorization requirement is stated in this policy. Coverage is determined by meeting FDA/ACIP-recommended age and clinical criteria for rotavirus vaccination (i.e., infants <8 months for FDA‑approved vaccines). Providers should verify member-specific benefit plan requirements prior to administration in case a plan requires prior authorization.
- Check member benefit plan for any plan-specific prior authorization or preventive service exclusion
- Confirm patient age and that administration follows ACIP/CDC schedule recommendations
Preventive Service Exclusion Risk
Preventive service exclusion risk: Some Aetna plans exclude coverage of preventive services. Providers must check the member’s benefit plan description to determine whether rotavirus vaccine administration is covered or excluded under that specific plan.
- Verify coverage through eligibility and benefits prior to billing
- If preventive services are excluded, obtain member financial responsibility acknowledgement as required by the plan
Not Specified / Additional Provider Actions
Not specified in these chunks: The policy excerpts do not list step therapy, sequencing requirements, or explicit authorization/denial triggers. Preserve clinical indications per medical necessity and experimental/investigational statements in the full policy.
- Follow ACIP/CDC recommendations and the policy's medical necessity criteria for eligible infants
- Consult full policy appendix for administration schedule
Coding and Documentation
Coding and documentation: Use the appropriate CPT/HCPCS and ICD-10 codes when billing for rotavirus vaccination and associated immunization encounters. Ensure documentation supports medical necessity and member eligibility.
- Covered CPT codes when criteria met: 90680 (Rotavirus vaccine, pentavalent, RV5, 3-dose schedule, oral)
- Covered CPT codes when criteria met: 90681 (Rotavirus vaccine, human attenuated, RV1, 2-dose schedule, oral)
- ICD-10: Z23 (Encounter for immunization) — document as immunization encounter
- Retain vaccine administration record, date of birth, lot numbers, and consent in the medical record
Clinical Policy Bulletins
Clinical Policy Bulletins are developed to assist in administering plan benefits and do not constitute medical advice. Treating providers are solely responsible for medical advice and treatment of members. Providers should consult the full Clinical Policy Bulletin for complete policy details, review history, and definitions.
- Refer to Clinical Policy Bulletin Notes and policy history for updates and definitions
- Understand that CPBs are not offers of coverage and do not replace clinical judgment
Background and Rationale
Rotavirus is a leading cause of severe diarrhea in infants and young children and is associated with substantial emergency department visits and hospitalizations. FDA-approved oral vaccines (RotaTeq and Rotarix) are indicated for the prevention of rotavirus gastroenteritis in infants and, together with ACIP guidance, form the basis for this policy’s coverage criteria. Clinical trials and public health data support vaccination to reduce severe rotavirus disease and related hospitalizations, while safety monitoring has included evaluation for intussusception.
