About coding Hemispasm
The ICD-10-CM code for Hemispasm is R25.2 (Cramp and spasm).
Within R25 (abnormal involuntary movements), R25.2 is specifically for cramp and spasm. Related codes cover abnormal head movements (R25.0), tremor, unspecified (R25.1), Fasciculation (R25.3), other abnormal involuntary movements (R25.8) and unspecified abnormal involuntary movements (R25.9).
The conditions in its Excludes2 note aren't part of R25.2, but may be coded alongside it if the patient has both: carpopedal spasm (R29.0), charley-horse (M62.831), infantile spasms (G40.4-), muscle spasm of back (M62.830) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
