About R25.2
R25.2 is the ICD-10-CM diagnosis code for cramp and spasm. It belongs to category R25 (abnormal involuntary movements), block R25-R29 (symptoms and signs involving the nervous and musculoskeletal systems) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
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.
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 729.82 (cramp of limb) and 781.0 (abnormal involuntary movements).
