F44.4Conversion disorder with motor symptom or deficit

F44.4 is the ICD-10-CM diagnosis code for conversion disorder with motor symptom or deficit. It belongs to category F44 (dissociative and conversion disorders), block F40-F48 (anxiety, dissociative, stress-related, somatoform and other nonpsychotic mental disorders) 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 F44 (dissociative and conversion disorders), F44.4 is specifically for conversion disorder with motor symptom or deficit. Related codes cover dissociative amnesia (F44.0), dissociative fugue (F44.1), dissociative stupor (F44.2), conversion disorder with seizures or convulsions (F44.5), conversion disorder with sensory symptom or deficit (F44.6), conversion disorder with mixed symptom presentation (F44.7), other dissociative and conversion disorders (F44.8) and dissociative and conversion disorder, unspecified (F44.9).

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 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.

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 300.11 (conversion disorder).
