About coding imprisonment
The ICD-10-CM code for imprisonment is Z65.1 (Imprisonment and other incarceration).
Within Z65, choose Z65.1 (Imprisonment and other incarceration) only when documentation doesn't support a more specific option: Conviction in civil and criminal proceedings without imprisonment (Z65.0), problems related to release from prison (Z65.2), problems related to other legal circumstances (Z65.3), victim of crime and terrorism (Z65.4), exposure to disaster, war and other hostilities (Z65.5), other specified problems related to psychosocial circumstances (Z65.8) and problem related to unspecified psychosocial circumstances (Z65.9).
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.
