About coding Institutionalization
The ICD-10-CM code for Institutionalization is Z62.22 (Institutional upbringing). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Z62.22.
Within Z62.2 (upbringing away from parents), Z62.22 is specifically for Institutional upbringing. Related codes cover child in welfare custody (Z62.21), child in custody of non-parental relative (Z62.23), child in custody of non-relative guardian (Z62.24) and other upbringing away from parents (Z62.29).
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.
