Parkinson's dis w/o dyskinesia, w/o mention of fluctuations

This code represents Parkinson's disease in a patient who does not exhibit dyskinesia (involuntary movements) and whose symptoms are stable without significant on/off fluctuations or wearing-off phenomena. It indicates a relatively uncomplicated presentation of Parkinson's disease, specifically excluding these common motor complications.

Use this code for patients diagnosed with Parkinson's disease who are not experiencing dyskinesia and whose motor symptoms are well-controlled or stable, without documented fluctuations in their response to medication. Documentation should explicitly state the absence of dyskinesia and fluctuations, or at least not mention their presence.

• Ensure documentation clearly negates the presence of dyskinesia and fluctuations; if these are present, a more specific code from the G20.A series should be used.
• Do not use this code if the patient has any documented dyskinesia, even mild, or if they experience "on-off" periods or wearing-off of medication effects.
• This code is typically used as a primary diagnosis when Parkinson's disease is the reason for the encounter, or as a secondary diagnosis when managing other conditions in a patient with stable Parkinson's.
