Excludes1 — never code together
The conditions below can never be reported together with Z86.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- personal history of infectious diseases specific to a body system
- sequelae of infectious and parasitic diseases (B90-B94)
Inclusion terms
