R20 is a non-billable ICD-10-CM category code for disturbances of skin sensation, so it cannot be submitted on claims. Use a more specific code from this category instead, such as R20.0, R20.1, R20.2, and R20.3. As a symptom code, it should not be used as a principal diagnosis once a related definitive diagnosis has been established.

Questions About R20Overview

Is R20 (Disturbances of skin sensation) a billable code?

No. This is a category header that groups the codes for disturbances of skin sensation, and headers cannot be submitted on claims. Claims for disturbances of skin sensation need a more specific code from this category, such as R20.0, R20.1, and R20.2.

Can R20 be a principal diagnosis?

Use it with care. This is a symptom code, so once a definitive diagnosis explaining the disturbances of skin sensation is established, that condition takes the principal position instead.
