Other disorders involving the immune mechanism, not elsewhere classified - D89
Excludes1: It indicates that the conditions described by two codes cannot occur together in the same patient. These codes are mutually exclusive.
Type 1 Excludes:
- hyperglobulinemia NOS (R77.1)
- monoclonal gammopathy (of undetermined significance) (D47.2)
Excludes2: This note means that the conditions described by two codes are not usually associated with each other but can sometimes occur together.
Type 2 Excludes:
- transplant failure and rejection (T86.-)
