About R20.2
R20.2 is the ICD-10-CM diagnosis code for Paresthesia of skin. It belongs to category R20 (disturbances of skin sensation), block R20-R23 (symptoms and signs involving the skin and subcutaneous tissue) 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 R20 (disturbances of skin sensation), R20.2 is specifically for Paresthesia of skin. Related codes cover anesthesia of skin (R20.0), hypoesthesia of skin (R20.1), Hyperesthesia (R20.3), other disturbances of skin sensation (R20.8) and unspecified disturbances of skin sensation (R20.9).
Don't report R20.2 together with the conditions in its Excludes1 note: acroparesthesia (I73.8).
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 782.0 (disturbance of skin sensation).
