Pediatric billing depends on getting the patient’s exact age right for every code selected, since well-child visit codes, immunization administration codes, and several diagnosis codes are all age-banded and denied outright when the age on the claim does not match the code billed.
Why This Specialty Is Billing-Complex
Preventive visit CPT codes change by age bracket (infant, early childhood, school age, adolescent), and vaccine administration is billed separately from the vaccine product itself, with different administration codes depending on whether counseling was provided. A single well-child visit can generate half a dozen line items that all have to agree with each other and with the patient’s date of birth.
Common CPT, ICD-10 & HCPCS Codes
- CPT 99381-99385 / 99391-99395 — preventive medicine visit, new/established patient, by age
- CPT 90460-90461 — immunization administration with counseling, first and each additional vaccine component
- CPT 90471-90474 — immunization administration without counseling
- ICD-10 Z00.129 — routine child health examination without abnormal findings
Documentation Standards
The note needs the patient’s age at the time of service to clearly support the age-banded preventive code billed, and for immunizations, a record of which vaccines were given, the counseling provided (if any), and the vaccine information statement (VIS) discussion. Sick visits billed alongside a well-child visit need modifier 25 and separate documentation of the acute problem addressed.
Common Denial Reasons & How to Prevent Them
- Denials when the age-banded preventive CPT code does not match the patient’s documented age
- Denials for vaccine administration codes billed without the corresponding vaccine product code
- Missing modifier 25 when a sick visit is billed alongside a well-child visit
- Denials for immunization counseling codes without documentation that counseling occurred
