About coding neuropathy serum
The ICD-10-CM code for neuropathy serum is G61.1 (Serum neuropathy).
Within G61 (inflammatory polyneuropathy), G61.1 is specifically for serum neuropathy. Related codes cover Guillain-Barre syndrome (G61.0), other inflammatory polyneuropathies (G61.8) and unspecified (G61.9).
Use an additional code for adverse effect, if applicable, to identify serum (T50.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
