About coding puberty
The ICD-10-CM code for puberty is Z00.3 (Encounter for examination for adolescent development state). The official index lists 11 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z00.3.
Within Z00 (encounter for general examination without complaint, suspected or reported diagnosis), Z00.3 is specifically for encounter for examination for adolescent development state. Related codes cover general adult medical examination (Z00.0), newborn, infant and child health examinations (Z00.1), examination for period of rapid growth in childhood (Z00.2), examination of potential donor of organ and tissue (Z00.5), examination for normal comparison and control in clinical research program (Z00.6), examination for period of delayed growth in childhood (Z00.7) and other general examination (Z00.8).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
