About coding emotional shock stress state
The ICD-10-CM code for emotional shock stress state is R45.7 (State of emotional shock and stress, unspecified).
Within R45, choose R45.7 (State of emotional shock and stress, unspecified) only when documentation doesn't support a more specific option: Nervousness (R45.0), Restlessness and agitation (R45.1), unhappiness (R45.2), Demoralization and apathy (R45.3), irritability and anger (R45.4), Hostility (R45.5), Violent behavior (R45.6) and other symptoms and signs involving emotional state (R45.8).
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 880 (Acute Adjustment Reaction and Psychosocial Dysfunction, relative weight 0.9306), in MDC 19 (Mental Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
