About coding poisoning screening
The ICD-10-CM code for poisoning screening is Z13.88 (Encounter for screening for disorder due to exposure to contaminants).
Within Z13.8 (encounter for screening for other specified diseases and disorders), Z13.88 is specifically for encounter for screening for disorder due to exposure to contaminants. Related codes cover digestive system disorders (Z13.81), musculoskeletal disorder (Z13.82), respiratory disorder NEC (Z13.83), dental disorders (Z13.84), nervous system disorders (Z13.85) and other disorder (Z13.89).
Don't report Z13.88 together with the conditions in its Excludes1 note: those exposed to contaminants without suspected disorders (Z57.-, Z77.-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
