About coding marital problem
The ICD-10-CM code for marital problem is Z63.0 (Problems in relationship with spouse or partner). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z63.0.
Within Z63 (other problems related to primary support group, including family circumstances), Z63.0 is specifically for problems in relationship with spouse or partner. Related codes cover problems in relationship with in-laws (Z63.1), absence of family member (Z63.3), Disappearance and death of family member (Z63.4), disruption of family by separation and divorce (Z63.5), dependent relative needing care at home (Z63.6), other stressful life events affecting family and household (Z63.7), other specified problems related to primary support group (Z63.8) and problem related to primary support group, unspecified (Z63.9).
Don't report Z63.0 together with the conditions in its Excludes1 note: counseling for spousal or partner abuse problems (Z69.1) and counseling related to sexual attitude, behavior, and orientation (Z70.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
