Medical Billing for Pediatric Practices: A Complete Guide

Unique Billing Challenges in Pediatrics

Pediatric practices deal with a unique billing mix: high Medicaid volume (EPSDT), vaccine billing complexity, well-child visit coding, and age-specific code requirements. Understanding these nuances prevents the most common revenue-loss mistakes.

Well-Child Visit (Preventive Medicine) Coding

Well-child visits are billed using preventive medicine codes (99381–99395) based on the patient's age range. If the physician identifies and addresses a new problem during the well-child visit, you can bill a separate problem-focused E/M code with modifier 25 in addition to the preventive medicine code.

Vaccine Billing for Pediatrics

Vaccine billing has two components that must both be billed: the vaccine product itself (CPT 90xxx series) and the administration code (90460 for patients through 18 years old when counseling is provided). Billing the vaccine without the administration code — or vice versa — results in underpayment.

EPSDT and Medicaid Billing

Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) is a comprehensive Medicaid benefit for patients under 21. EPSDT requires different coding and documentation than standard well-child care. Understanding state-specific EPSDT requirements is essential for pediatric practices with significant Medicaid volume.

Pediatric Coding Benchmarks

Many pediatric practices leave revenue on the table because they undercode E/M visits (using 99213 when 99214 is supported) or fail to bill same-day problem visits alongside well-child codes. A virtual coder identifies and captures all billable services.
