Z56.4Discord with boss and workmates

Z56.4 is the ICD-10-CM diagnosis code for discord with boss and workmates. It belongs to category Z56 (problems related to employment and unemployment), 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 Z56 (problems related to employment and unemployment), Z56.4 is specifically for discord with boss and workmates. Related codes cover unemployment, unspecified (Z56.0), change of job (Z56.1), threat of job loss (Z56.2), stressful work schedule (Z56.3), Uncongenial work environment (Z56.5), other physical and mental strain related to work (Z56.6), other problems related to employment (Z56.8) and unspecified problems related to employment (Z56.9).

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.

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 V62.1 (adverse effects of work environment).
