R20Disturbances of skin sensation

R20 is the ICD-10-CM diagnosis code for disturbances of skin sensation. It belongs to 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 a header code, so it can't be reported by itself; one of its 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: R20.0 (skin), R20.1 (skin), R20.2 (skin), R20.3 (Hyperesthesia), R20.8 (sensation) and R20.9 (sensation).

Don't report R20 together with the conditions in its Excludes1 note: dissociative anesthesia and sensory loss (F44.6) and psychogenic disturbances (F45.8).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
