R62.50 — Unspecified lack of expected normal physiological development in childhood
Is R62.50 billable?
Yes, but R62.50 is an unspecified code. R62.50 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, R62.50 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting R62.50 — the more specific alternatives are listed below.
