Pediatric Coding Alert

Question: Our physician billed 90634, 90710, and 90606 for vaccines given to a 5-year-old patient. The insurance company denied payment and said they required a modifier. What should we have done differently?

Answer: According to standard CPT coding, vaccine codes do not require modifiers on the associated E/M code. However, you might need to include modifier 25 (Significant, separately identifiable evaluation and  management service by the same physician on the same day of the procedure or other service) if your insurance company requires it -- which might be why you received a denial.

Well check: If your physician administered vaccines on the same day as a well visit, code the well visit with the appropriate code such as 99393 (Periodic comprehensive preventive medicine reevaluation and management of an individual including an age and gender appropriate history, examination, counseling/anticipatory guidance/risk factor reduction interventions, and the ordering of laboratory/diagnostic procedures, established patient; late childhood [age 5 through 11 years]). You might need to append modifier 25 if vaccinations are given, depending on the payer's guidelines.

Sick visit: If the child visits because of another problem and receives immunizations during the visit, report the vaccines with the appropriate office visit code from 99212-99214 (Office or other outpatient visit for the evaluation and management of an established patient ...).

Then report the vaccine codes: 90634 (Hepatitis A vaccine, pediatric/adolescent doage-3 dose schedule, for intramuscular use), 90696 (Diphtheria, tetanus toxoids, acellular pertussis vaccine and poliovirus vaccine, inactivated -D-TaP-IPV], when administered to children 4 through 6 years of age, for intramuscular use), and 90710 (Measles, mumps, rubella, and varicella vaccine [MMRV], live, for subcutaneous use).
