About this code

Encounter for examination for adolescent development state.

Z00.3 is an ICD-10-CM diagnosis code for encounter for examination for adolescent development state. It sits in the 21. Factors influencing health status chapter of the U.S. clinical modification, under category Z00.

This code is billable on U.S. healthcare claims when supported by appropriate clinical documentation. The patient chart must establish the diagnosis, capture any clinical detail encoded in the code (severity, laterality, encounter type, complications where applicable), and demonstrate medical necessity for the billed services.

Payer-specific coverage rules vary. Always cross-check against the current Local Coverage Determinations (LCDs) and National Coverage Determinations (NCDs) for the payer adjudicating the claim, plus any specialty-specific CMS Medicare Administrative Contractor guidance.

What practitioners watch for on Z00.3.

Chapter-level billing guidance for factors influencing health status codes. Code-specific notes ship as the dataset matures.

Documentation

Z-prefix codes describe encounters that are not for a specific disease (screening, follow-up, family history, status codes). Document the specific reason for encounter; some Z-codes are limited to particular settings or as primary vs additional.

Common denial categories

  • CO-16: Information missing or incorrect on the claim or in supporting documentation. Add documentation specificity that supports the coded detail; resubmit with corrected information.
  • CO-50: Service not deemed medically necessary by the payer. Confirm the diagnosis-procedure relationship matches LCD/NCD coverage, attach clinical justification, appeal with documentation.
  • CO-11: Diagnosis is inconsistent with the procedure performed. Verify the diagnosis-to-procedure pairing per payer policy; correct the linked diagnosis pointer or the procedure code.

Coverage signal

Coverage for screening Z-codes follows the USPSTF Grade A and B preventive services list under ACA, with no patient cost-sharing on most commercial plans. Medicare uses its own preventive services list.
