G81.90 is a billable diagnosis code used to specify a medical diagnosis of hemiplegia, unspecified affecting unspecified side. The code G81.90 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code G81.90 might also be used to specify conditions or terms like alternating hypoglossal hemiplegia, ataxic hemiparesis, cerebral hemiparesis, cerebral hemiplegia, complete unilateral paralysis , complete unilateral paresis, etc.
Unspecified diagnosis codes like G81.90 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
Also called: Hemiplegia, Palsy, Paraplegia, Quadriplegia
Paralysis is the loss of muscle function in part of your body. It happens when something goes wrong with the way messages pass between your brain and muscles. Paralysis can be complete or partial. It can occur on one or both sides of your body. It can also occur in just one area, or it can be widespread. Paralysis of the lower half of your body, including both legs, is called paraplegia. Paralysis of the arms and legs is quadriplegia.
Most paralysis is due to strokes or injuries such as spinal cord injury or a broken neck. Other causes of paralysis include
- Nerve diseases such as amyotrophic lateral sclerosis
- Autoimmune diseases such as Guillain-Barre syndrome
- Bell's palsy, which affects muscles in the face
Polio used to be a cause of paralysis, but polio no longer occurs in the U.S.
