About coding head movement abnormal
The ICD-10-CM code for head movement abnormal is R25.0 (Abnormal head movements).
Within R25 (abnormal involuntary movements), R25.0 is specifically for abnormal head movements. Related codes cover tremor, unspecified (R25.1), cramp and spasm (R25.2), Fasciculation (R25.3), other abnormal involuntary movements (R25.8) and unspecified abnormal involuntary movements (R25.9).
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.
