About coding Hyperesthesia
The ICD-10-CM code for Hyperesthesia is R20.3 (Hyperesthesia). The official index lists 4 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R20.3.
Within R20 (disturbances of skin sensation), R20.3 is specifically for Hyperesthesia. Related codes cover anesthesia of skin (R20.0), hypoesthesia of skin (R20.1), Paresthesia of skin (R20.2), other disturbances of skin sensation (R20.8) and unspecified disturbances of skin sensation (R20.9).
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.
