About coding sense or sensation diminished
The ICD-10-CM code for sense or sensation diminished is R20.8 (Other disturbances of skin sensation).
Within R20, choose R20.8 (Other disturbances of skin sensation) only when documentation doesn't support a more specific option: anesthesia of skin (R20.0), hypoesthesia of skin (R20.1), Paresthesia of skin (R20.2), Hyperesthesia (R20.3) 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.
