Answer: No, you’ll need a pair of diagnosis codes to complete the picture of this patient’s condition. On the claim, report G20 (Parkinson’s disease) along with F06.7 (Mild neurocognitive disorder due to known physiological condition) to represent the neurocognitive disorder.

More about F06.7: ICD-10 reminds coders to “Code first the underlying physiological condition, such as:

• “Alzheimer’s disease (G30.-)
• “frontotemporal neurocognitive disorder (G31.09)
• “human immunodeficiency virus [HIV] disease (B20)
• “Huntington’s disease (G10)
• “Neurocognitive disorder with Lewy bodies (G31.83)
• “Parkinson’s disease (G20)
• “systemic lupus erythematosus (M32.-)
• “traumatic brain injury (S06.-)
• “vitamin B deficiency (E53-).”
