Pediatrics Billing & Coding Tips

  • Use age-specific well-child CPT codes (99381–99385 new, 99391–99395 established) — billing the wrong age band triggers claim edits.
  • Z23 is the primary diagnosis for immunization-only visits; add the specific vaccine product codes from the 90xxx series.
  • ADHD coding requires specifying subtype: F90.0 (predominantly inattentive), F90.1 (predominantly hyperactive-impulsive), or F90.2 (combined).
  • Developmental screening (96110) can be billed in addition to a well-child E&M at the same visit without a modifier.

Frequently Asked Questions

What ICD-10 code is used for a well-child visit?

Z00.12x codes are used for routine child health examinations. Z00.129 is the unspecified age version. Z00.121 is for children with abnormal findings. Select the appropriate code based on age and findings documented.

What CPT code is used for a 4-year-old well visit?

99392 covers preventive medicine for established patients aged 1–4 years. For a new patient at the same age, use 99382. Both include a comprehensive history, exam, and counseling.

Can I bill for developmental screening separately?

Yes. 96110 (developmental screening) and 96127 (behavioral/emotional screening) can both be billed on the same day as a preventive E&M without a modifier. Each must have a documented instrument, score, and clinician review.

What is the ADHD code for combined type?

F90.2 is the ICD-10 code for ADHD, combined presentation (formerly combined type in DSM-IV). It requires documentation of both inattentive and hyperactive-impulsive symptoms meeting DSM-5 criteria for at least 6 months.
