F95.0Transient tic disorder

F95.0 is the ICD-10-CM diagnosis code for transient tic disorder. It belongs to category F95 (tic disorder), block F90-F98 (behavioral and emotional disorders with onset usually occurring in childhood and adolescence) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within F95 (tic disorder), F95.0 is specifically for transient tic disorder. Related codes cover chronic motor or vocal tic disorder (F95.1), Tourette's disorder (F95.2), other tic disorders (F95.8) and unspecified (F95.9).

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 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.

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 307.21 (transient tic disorder).
