Paresthesia of skin

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015
LAST UPDATED09/11/2025

Code Description

ICD-10 R20.2 is a billable code used to indicate a diagnosis of paresthesia of skin.

Key Diagnostic Point:

Paresthesia of skin refers to abnormal sensations in the skin, such as tingling, prickling, or numbness, that are not attributed to a specific underlying condition. This symptom can arise from various causes, including nerve compression, peripheral neuropathy, or systemic diseases. Patients may describe sensations that can be transient or chronic, and they may occur in localized areas or be more generalized. The clinical significance of paresthesia can vary widely, from benign causes like anxiety or temporary nerve compression to more serious conditions such as diabetes mellitus or multiple sclerosis. Accurate diagnosis often requires a thorough patient history, physical examination, and possibly additional diagnostic tests to identify any underlying conditions contributing to the paresthesia. It is essential for healthcare providers to document the characteristics of the paresthesia, including onset, duration, and associated symptoms, to guide appropriate management and coding.
