Documentation Required
- Billing and coding for immunizations must follow the coverage indications, limitations, and medical necessity criteria set forth in the associated Local Coverage Determination LCD L34596 (Immunizations).
- Document the injury or exposure details and the clinician's determination that the encounter meets criteria for post-exposure vaccination (e.g., wound characteristics, exposure type).
- Document patient immunization history, including dates of primary immunization and most recent booster, to support tetanus and rabies vaccine decisions.
- For Hepatitis A vaccine coverage, document exposure type (close personal contact or ingestion of contaminated food/water) and rationale for vaccination; if concomitant IG used, document both products administered.
Key Coverage Criteria
- When the patient has not been previously immunized for rabies, coverage includes RIG (half IM and half wound on day 0) plus HDCV on days 0, 3, 7, 14, and 28.
- Vaccinations are covered only when directly related to treatment of an injury or direct exposure to a disease/condition listed in this policy.
- Preventive immunizations are covered for pneumococcal, hepatitis B, and influenza vaccines.
- Tdap or Td vaccines are covered when given for an acute injury in a person who is incompletely immunized for tetanus.
- For tetanus-prone wounds, tetanus toxoid (booster) should be administered if the patient has not had a booster dose within the past 5 years.
- For clean, minor wounds, tetanus toxoid (booster) is covered only if the patient has not had a booster dose within the past 10 years.
