Audit Defense & Denial Intelligence
Research-based denial patterns from OrbDoc Bill Analyzer
1. Billed without primary code 90460 - add-on code cannot stand alone
Common90461 is add-on code that MUST be billed with 90460. Cannot bill 90461 alone. Denials occur when 90461 submitted without corresponding 90460 on same claim (claim formatting error) or when only additional components billed without first component.
Common Causes
- • Billing software error - 90461 submitted, 90460 not on same claim
- • Coder billed only additional components, forgot first component
- • Split billing across dates - 90460 billed on different date than 90461
Resolution Strategy
Verify 90460 billed on same claim as 90461. Corrected claim should include: one unit 90460 (first vaccine component) + appropriate units 90461 (each additional component). Example: DTaP given = 90460 x1 + 90461 x2. If 90460 denied for separate reason (no counseling documented), must resolve that denial first - cannot bill 90461 without 90460. Resubmit complete claim with both codes together.
2. Used for adult patient - should use 90472 instead (age 19+)
Occasional90461 is pediatric code (birth through 18 years) for additional vaccine components with counseling. For adults 19+, must use 90472 for additional vaccines regardless of counseling. Age restriction same as 90460.
Common Causes
- • Young adult (19-26) receiving multiple vaccines - HPV + Tdap + flu
- • College health clinic using pediatric codes for college students
- • Provider unfamiliar with age cutoff for vaccine administration codes
Resolution Strategy
Verify patient age at time of service. If 19+ years: recode to 90471 (first vaccine) + 90472 (each additional vaccine) and resubmit. Adult vaccine administration does not distinguish counseling vs. non-counseling - all use 90471/90472 regardless. If truly 18 years or younger: appeal with patient birthdate documentation confirming pediatric age.
