2026 ICD-10-CM Diagnosis Code R62Lack of expected normal physiological development in childhood and adults
R62 is a non-billable ICD-10-CM category code for lack of expected normal physiological development in childhood and adults, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R62.0, R62.50, R62.51, and R62.52. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.
