Valid for Submission
G23.1 is a billable diagnosis code used to specify a medical diagnosis of progressive supranuclear ophthalmoplegia [steele-richardson-olszewski]. The code G23.1 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 G23.1 might also be used to specify conditions or terms like progressive supranuclear ophthalmoplegia, progressive supranuclear palsy, supranuclear gaze palsy or supranuclear paralysis.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G23.1:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Index to Diseases and Injuries
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code G23.1 are found in the index:
- - Palsy - See Also: Paralysis; - G83.9
- - Paralysis, paralytic (complete) (incomplete) - G83.9
- - Willige-Hunt disease or syndrome - G23.1
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Progressive supranuclear ophthalmoplegia
- Progressive supranuclear palsy
- Supranuclear gaze palsy
- Supranuclear paralysis
- SUPRANUCLEAR PALSY PROGRESSIVE-. a degenerative disease of the central nervous system characterized by balance difficulties; ocular motility disorders supranuclear ophthalmoplegia; dysarthria; swallowing difficulties; and axial dystonia. onset is usually in the fifth decade and disease progression occurs over several years. pathologic findings include neurofibrillary degeneration and neuronal loss in the dorsal mesencephalon; subthalamic nucleus; red nucleus; pallidum; dentate nucleus; and vestibular nuclei. from adams et al. principles of neurology 6th ed pp1076 7
Convert G23.1 to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code G23.1 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Progressive Supranuclear Palsy
Also called: PSP, Richardson-Steele-Olszewski syndrome, Steele-Richardson-Olszewski syndrome
What is progressive supranuclear palsy (PSP)?
Progressive supranuclear palsy (PSP) is a rare brain disease. It happens because of damage to nerve cells in the brain. PSP affects your movement, including control of your walking and balance. It also affects your thinking and eye movement.
PSP is progressive, which means that it gets worse over time.
What causes progressive supranuclear palsy (PSP)?
Researchers don't know what causes most cases of PSP. In rare cases, the cause is a mutation in a certain gene.
One sign of PSP is abnormal clumps of tau in nerve cells in the brain. Tau is a protein in your nervous system, including in nerve cells. Some other diseases also cause a buildup of tau in the brain, including Alzheimer's disease.
Who is at risk for progressive supranuclear palsy (PSP)?
PSP usually affects people over 60, but in some cases it can start earlier. It is more common in men.
What are the symptoms of progressive supranuclear palsy (PSP)?
Symptoms are very different in each person, but they may include
- A loss of balance while walking. This is often the first symptom.
- Speech problems
- Trouble swallowing
- A blurring of vision and problems controlling eye movement
- Changes in mood and behavior, including depression and apathy (a loss of interest and enthusiasm)
- Mild dementia
How is progressive supranuclear palsy (PSP0 diagnosed?
There is no specific test for PSP. It can be difficult to diagnose, because the symptoms are similar to other diseases such as Parkinson's disease and Alzheimer's disease.
To make a diagnosis, your health care provider will take your medical history and do physical and neurological exams. You may have an MRI or other imaging tests.
What are the treatments for progressive supranuclear palsy (PSP)?
There is currently no effective treatment for PSP. Medicines may reduce some symptoms. Some non-drug treatments, such as walking aids and special glasses, may also help. People with severe swallowing problems may need gastrostomy. This is a surgery to insert a feeding tube into the stomach.
PSP gets worse over time. Many people become severely disabled within three to five years after getting it. PSP isn't life-threatening on its own. It can still be be dangerous, because it increases your risk of pneumonia, choking from swallowing problems, and injuries from falling. But with good attention to medical and nutritional needs, many people with PSP can live 10 or more years after the first symptoms of the disease.

Progressive supranuclear palsy Progressive supranuclear palsy is a brain disorder that affects movement, vision, speech, and thinking ability (cognition). The signs and symptoms of this disorder usually become apparent in mid- to late adulthood, most often in a person's 60s. Most people with progressive supranuclear palsy survive 5 to 9 years after the disease first appears, although a few affected individuals have lived for more than a decade.Loss of balance and frequent falls are the most common early signs of progressive supranuclear palsy. Affected individuals have problems with walking, including poor coordination and an unsteady, lurching gait. Other movement abnormalities develop as the disease progresses, including unusually slow movements (bradykinesia), clumsiness, and stiffness of the trunk muscles. These problems worsen with time, and most affected people ultimately require wheelchair assistance.Progressive supranuclear palsy is also characterized by abnormal eye movements, which typically develop several years after the other movement problems first appear. Restricted up-and-down eye movement (vertical gaze palsy) is a hallmark of this disease. Other eye movement problems include difficulty opening and closing the eyelids, infrequent blinking, and pulling back (retraction) of the eyelids. These abnormalities can lead to blurred vision, an increased sensitivity to light (photophobia), and a staring gaze.Additional features of progressive supranuclear palsy include slow and slurred speech (dysarthria) and trouble swallowing (dysphagia). Most affected individuals also experience changes in personality and behavior, such as a general loss of interest and enthusiasm (apathy). They develop problems with cognition, including difficulties with attention, planning, and problem solving. As the cognitive and behavioral problems worsen, affected individuals increasingly require help with personal care and other activities of daily living.
