About coding cataract screening
The ICD-10-CM code for cataract screening is Z13.5 (Encounter for screening for eye and ear disorders).
Within Z13 (encounter for screening for other diseases and disorders), Z13.5 is specifically for encounter for screening for eye and ear disorders. Related codes cover screening for diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism (Z13.0), screening for diabetes mellitus (Z13.1), screening for nutritional, metabolic and other endocrine disorders (Z13.2), screening examination for mental health and behavioral disorders (Z13.3), screening for certain developmental disorders in childhood (Z13.4), screening for cardiovascular disorders (Z13.6), screening for genetic and chromosomal anomalies (Z13.7), screening for other specified diseases and disorders (Z13.8) and 1 more.
The conditions in its Excludes2 note aren't part of Z13.5, but may be coded alongside it if the patient has both: encounter for general hearing examination (Z01.1-) and encounter for general vision examination (Z01.0-).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
