Wiki G20 vs G90.3 correct DX coding

[shelley.gacek@yahoo.com]

If the provider is stating throughout the entire MR Parkinson's plus syndrome what is the correct ICD 10 code??
G20 for Parkinson's or G90.3 for Multi system degeneration of the autonomic nervous system???

Without documentation of multiple affected systems, I would not take the leap that "plus" means Multi system degeneration of the autonomic nervous system. When we index "Syndrome, Parkinson's", we are guided to see "Parkinsonism" which codes to G20 if no other sub-terms apply.
