About coding Workplace stress
The ICD-10-CM code for Workplace stress is Z56.6 (Other physical and mental strain related to work).
Within Z56, choose Z56.6 (Other physical and mental strain related to work) only when documentation doesn't support a more specific option: unemployment, unspecified (Z56.0), change of job (Z56.1), threat of job loss (Z56.2), stressful work schedule (Z56.3), discord with boss and workmates (Z56.4), Uncongenial work environment (Z56.5), 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.
