Medi-Cal RSV vaccine billing expands age eligibility and modifier rules
Oct 11, 2026 edition · GC-2026-0277 · Published 2026-10-11 · Version 3 · Final
DHCS lowers code 90683's minimum age to fifty retroactively and applies SK only to ages fifty through seventy-four. The correction process concerns qualifying system-related denials, while age, modifier, and service-date checks remain separate.
What happened
For service dates from June 12, 2025, the notice makes the RSV vaccine code 90683 available from age fifty. Modifier SK is required for members aged fifty through seventy-four and is not required for members seventy-five and older. A single minimum-age edit therefore does not capture the full billing change: the age at service determines the modifier treatment as well as whether the updated minimum is met.
DHCS plans an Erroneous Payment Correction for appropriately submitted claims from the effective date that were denied because the system had not implemented the policy. Providers may instead correct and resubmit earlier denials using existing claim-inquiry and timeliness instructions. Updated manual sections are forthcoming. Those alternatives support reconciliation of actual eligible denials; they do not prove every denied vaccine claim will pay automatically or that the system correction has already completed.

Why it matters
DHCS will implement an erroneous-payment correction for appropriately submitted claims denied because system changes were missing. Providers may also correct and resubmit under existing timeliness instructions.
Recommended action
Update age and modifier edits, identify eligible denied claims and reconcile reprocessing against any resubmissions. Playbook dates are recommended internal targets, except any explicitly identified agency date.
