Overview
Pediatric billing runs on two things most other specialties don't deal with at this scale: immunization administration coding and state Medicaid MCO variation. Vaccines for Children program inventory must be billed separately from privately purchased stock, and well-child periodicity schedules differ by state.
Why these claims get denied
The denial reasons we see most often in pediatrics — and what our pre-billing checks are built to catch.
- VFC-supplied vaccines billed with a product charge instead of administration only
- Immunization administration units not matched to the number of components
- Well-child visit billed outside the state's periodicity schedule
- Sick visit and well visit same day without modifier 25 on the E/M
- Developmental screening billed without the required documentation
- Medicaid MCO-specific rules applied as if all plans were the same

Common questions
How should VFC vaccines be billed?
State-supplied Vaccines for Children doses are billed with administration codes only — no product charge. Including a product line on a VFC dose triggers a denial and, in some states, a program compliance issue.
How are immunization administration units counted?
90460 covers the first component of each vaccine with counseling, and 90461 covers each additional component. Units follow components, not vials, which is where most administration denials originate.
Why do well-child visits deny?
Usually because the visit falls outside the state's periodicity schedule. Medicaid programs each publish their own schedule, and MCO variation within a state adds another layer. We load the schedule for the plans you actually contract with.
