About coding habit tic
The ICD-10-CM code for habit tic is F95.9 (Tic disorder, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on F95.9.
Within F95, choose F95.9 (unspecified) only when documentation doesn't support a more specific option: transient tic disorder (F95.0), chronic motor or vocal tic disorder (F95.1), Tourette's disorder (F95.2) and other tic disorders (F95.8).
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 091 (Other Disorders of Nervous System with MCC, relative weight 1.7046), DRG 092 (Other Disorders of Nervous System with CC, relative weight 1.0239) and DRG 093 (Other Disorders of Nervous System without CC/MCC, relative weight 0.7783), in MDC 01 (Diseases and Disorders of the Nervous System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
