About Z63.0
Z63.0 is the ICD-10-CM diagnosis code for problems in relationship with spouse or partner. It belongs to category Z63 (other problems related to primary support group, including family circumstances), block Z55-Z65 (persons with potential health hazards related to socioeconomic and psychosocial circumstances) and chapter 21 (factors influencing health status and contact with health services). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
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.
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.
It is not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.
It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as V61.8 (other specified family circumstances).
