ICD-10 Code G56.11 – Other lesions of median nerve, right upper limb (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G56.11 – Other lesions of median nerve, right upper limb
What it is
This code identifies a non-specified disorder affecting the median nerve in the right upper limb. Use it when documentation describes another lesion, injury, or abnormality of the right median nerve without a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Median nerve involvement may be associated with sensory changes, pain, weakness, or reduced hand function in the right upper extremity.
When to use this code
Use G56.11 when the provider documents an other lesion of the right median nerve and no more specific median nerve disorder is named. It may apply when the record supports nerve dysfunction but does not fit a defined entrapment or traumatic category. Check documentation for laterality and exact wording.
Do not use for
Do not use this code for median nerve conditions documented on the left side or for unspecified laterality. Also avoid it when the record clearly identifies a different nerve disorder or a more specific diagnosis.
Coding tip
Verify the provider’s exact nerve and side before assigning the code.
