About coding Tantrum
The ICD-10-CM code for Tantrum is F91.8 (Other conduct disorders).
Within F91, choose F91.8 (Other conduct disorders) only when documentation doesn't support a more specific option: conduct disorder confined to family context (F91.0), conduct disorder, childhood-onset type (F91.1), conduct disorder, adolescent-onset type (F91.2), Oppositional defiant disorder (F91.3) and conduct disorder, unspecified (F91.9).
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 886 (Behavioral and Developmental Disorders, relative weight 1.8678), 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.
