Neurologic Diseases

The brain, spinal cord, and nerves make up the nervous system. Together they control all the workings of the body. When something goes wrong with a part of your nervous system, you can have trouble moving, speaking, swallowing, breathing, or learning. You can also have problems with your memory, senses, or mood.

Questions About R20.2Overview

Is R20.2 (Disturbances of skin sensation) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report paresthesia of skin on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Can R20.2 be a principal diagnosis?

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

What is the ICD-9 equivalent of R20.2?

Under the General Equivalence Mappings, paresthesia of skin converts to ICD-9-CM 782.0 (skin sensation disturb). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
