2023 ICD-10-CM Diagnosis Code G23.1

Progressive supranuclear ophthalmoplegia [Steele-Richardson-Olszewski]

2016 2017 2018 2019 2020 2021 2022 2023 Billable/Specific Code

• G23.1 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
• Short description: Progressive supranuclear ophthalmoplegia
• The 2023 edition of ICD-10-CM G23.1 became effective on October 1, 2022.
• This is the American ICD-10-CM version of G23.1 - other international versions of ICD-10 G23.1 may differ.

• Progressive supranuclear ophthalmoplegia
• Progressive supranuclear palsy

• 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)
• A progressive neurological disorder characterized by ophthalmoplegia, dystonia, memory impairment, personality disorders, and dementia. Etiology is unknown.
• A rare neurodegenerative disorder characterized by gait and balance difficulties and loss of coordination of eye movements.
• Progressive supranuclear palsy (psp) is a rare brain disease. It affects brain cells that control the movement of your eyes. This leads to serious and permanent problems with balance and the way you walk. It usually occurs in middle-aged or elderly people. Symptoms are very different in each person, but may include personality changes, speech, vision and swallowing problems. Doctors sometimes confuse psp with parkinson's disease or alzheimer's disease. Psp has no cure and no effective treatments. Walking aids, special glasses and certain medicines might help somewhat. Although the disease gets worse over time, it isn't fatal on its own. However, psp is dangerous because it increases your risk of pneumonia and choking from swallowing problems and injuries from falling.
• Spastic weakness of the muscles innervated by the cranial nerves, i.e., the muscle of the face, pharynx, and tongue, due to bilateral lesions of the corticospinal tract.
