About ICD-9-CM V21.8
V21.8 is an ICD-9-CM diagnosis code for other specified constitutional states in development. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 2 ICD-10-CM codes, such as Z00.2 (Encounter for examination for period of rapid growth in childhood) and Z00.3 (Encounter for examination for adolescent development state). All of these are approximate matches, so review the record to pick the right one.
