ICD-10 Code G83.0 – Diplegia of upper limbs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G83.0 – Diplegia of upper limbs
What it is
G83.0 identifies diplegia affecting both upper limbs. Use it when documentation describes bilateral weakness, paralysis, or impaired motor control limited to the arms.
Clinical signs
Clinical features may include reduced strength, limited voluntary movement, abnormal tone, or poor coordination in both upper extremities. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents diplegia of the upper limbs or a similar bilateral arm paralysis pattern. It may apply in neurologic disorders, congenital conditions, or acquired central nervous system injury if the record specifies upper-limb involvement. Check documentation for laterality and whether the finding is truly diplegia rather than generalized weakness.
Do not use for
Do not use this code for weakness of one arm, generalized paralysis, or lower-limb diplegia. If the note only says “weakness” without clear bilateral upper-limb diplegia, check documentation.
Coding tip
Code G83.0 only when the record clearly states bilateral upper-limb diplegia; otherwise, query for specificity.
