Hint: Aim for specificity in diagnoses to avoid, in some cases, ‘Return to Provider.’ Residents living in nursing homes may be living with movement disorders. Although Parkinson’s disease is one of the best known movement disorders, make sure you’re familiar with other diagnoses — and how to find the correct ICD-10-CM code. There’s an entire ICD-10 code set dedicated to “Extrapyramidal and movement disorders (G20-G26).” To get a handle on the code set as a whole, we asked Beth Schleeper, COC, CPC, CPCO, CDEO, CPB, CPMA, CPPM, CRC, CPC-I, CEMC, CANPC, CEMA, owner/ instructor of Advanced Coding Services in Phoenix, for some pointers on finding the right diagnosis code for each movement disorder. Distinguish Parkinson’s/Secondary Parkinsonism At the forefront of the movement disorder sequence is G20 (Parkinson’s disease). Use this for all residents suffering from Parkinson’s disease, as well as: You’ll also need to know how to code secondary Parkinsonism, which you’d report with one of the following codes: According to Medline, National Library of Medicine, “secondary parkinsonism is when symptoms similar to Parkinson disease are caused by certain medicines, a different nervous system disorder, or another illness. “Parkinsonism refers to any condition that involves the types of movement problems seen in Parkinson disease. These problems include tremors, slow movement, and stiffness of the arms and legs.” Also: You will need to select another ICD-10 code “if there is an adverse effect, to identify the drug,” Schleeper says. Each of the secondary parkinsonism codes has its own “Use additional code” instruction, printed in red under the code listing. Look to G24.- for Dystonia Another movement disorder that is well-represented in G20-G26 is dystonia, which you’ll report with codes from the following range: “Dystonia is a movement disorder in which your muscles contract involuntarily, causing repetitive or twisting movements,” according to the Mayo Clinic. Get Familiar With Other Dx Groups in G20-G26 While the aforementioned diagnoses get most of the attention in the extrapyramidal and movement disorders code set, there are a few more codes out there that round out G20-G26. Check out this rundown of those other codes: Other degenerative diseases of basal ganglia: Report codes from the following range: Other extrapyramidal and movement disorders: Report codes from the following range: Extrapyramidal and movement disorders in diseases classified elsewhere: Report code G26 (Extrapyramidal and movement disorders in diseases classified elsewhere). Remember: Using the most specific diagnosis possible is important for being reimbursed for the care your team provides. For example, while a myoclonus diagnosis falls under medical management, per the Patient Driven Payment Model, “essential tremor” and “drug-induced tremor” are both categorized as “return to provider.”
