Key changes include: new reimbursement policies for preventive medicine/sick visits on same day, genetic testing (once per lifetime), and treatment rooms; enhanced claims accuracy requirements for sepsis and newborn DRGs requiring full medical records; electronic explanations of payment launching mid-July; and pharmacy prior authorization updates effective July 1, 2026.
Action Required
REQUIREMENTS:
By June 15, 2026:
- Billing team must review and implement the new reimbursement policies: (1) Preventive Medicine and Sick Visits on the Same Day (effective April 1, 2026 for MA; July 1, 2026 for Medicaid), (2) Genetic Tests: Once per Lifetime (effective July 1, 2026 for MA and Medicaid), and (3) Treatment Rooms policy (effective July 1, 2026 for MA). Update billing software to enforce visit bundling rules and genetic test frequency limitations.
By June 30, 2026:
- Billing team must ensure claims for inpatient sepsis and newborn DRG cases (effective July 1, 2026 for MA) include full medical records with claims. Update submission workflow to require records attachment and add validation rules to prevent claims rejection.
By June 1, 2026:
- Update prior authorization protocols for medications billed under the medical benefit per pharmacy updates (effective July 1, 2026 for Medicaid). Obtain updated medication lists and integrate step therapy requirements into billing system.
Before mid-July 2026:
- Billing and front office teams must prepare for electronic Explanations of Payment transition. Update processes for reviewing and responding to electronic EOPs instead of paper documents. Train staff on new portal access.
Before May 1, 2025:
- Ensure medical records are submitted with facility inpatient claims per Commercial plan requirements. Add mandatory documentation checklist to inpatient encounter forms.
Consequences: Claims missing required medical records will be denied. Failure to enforce new reimbursement policy limits (same-day visits, genetic test frequency) will result in overpayment recovery demands.
