    ICD-10-CM Code For Disturbances Of Skin Sensation: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group R20 includes codes for abnormal skin sensations such as numbness, tingling, and paresthesia localized to the face, limbs, or other skin regions. These ICD-10-CM diagnosis codes are used to document clinical encounters where altered cutaneous sensation is the principal finding, capturing anatomic location and any specified laterality or distribution. Accurate coding within the ICD-10-CM R20 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM R20: Disturbances Of Skin Sensation Overview

    The ICD-10-CM R20 group captures sensory disturbances of the skin such as numbness, tingling, and paresthesia affecting specified anatomic regions. These diagnoses target the integumentary and peripheral nervous systems where altered cutaneous sensation is the primary complaint. Accurate coding matters for correct clinical documentation and appropriate claim processing tied to the reported neurologic or dermatologic presentation.

    Typical Clinical Scenarios

    • An elderly patient presents to the emergency department after a fall, reporting sudden onset numbness and tingling localized to the left hand and forearm; neurologic exam is otherwise unremarkable and stroke is ruled out. The symptoms are acute sensory disturbance without visible skin lesion or rash, prompting assignment of a skin sensation disturbance code while further neurologic workup proceeds. Typical codes: R20.2, R20.3
    • A middle-aged patient with longstanding type 2 diabetes attends a primary care visit complaining of chronic burning and reduced sensation in both feet that has progressed over months, interfering with sleep. Because the presentation reflects persistent paresthesia and hypesthesia consistent with peripheral neuropathy affecting skin sensation, a code from this group is used alongside diabetes-related codes. Typical codes: R20.1, R20.2
    • A young adult presents to urgent care with an acute, localized area of unilateral facial numbness following a shingles outbreak; rash has crusted but the patient reports persistent anesthesia and altered tactile perception in the affected dermatome. The sensory deficit is a complication of the prior herpes zoster infection and is coded as a disturbance of skin sensation to document the ongoing sensory sequela. Typical codes: R20.0, R20.9
