Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

About the Z29 Code Range
The ICD-10 code section Z29 covers encounters for various prophylactic measures, which are preventive treatments used to guard against specific diseases and conditions before any symptoms appear.
This section includes detailed codes such as Z29.1 for prophylactic immunotherapy, and more specific types like Z29.11 for respiratory syncytial virus (RSV) immunotherapy or Z29.12 for antivenin administration. It also encompasses encounters for prophylactic treatments like Rho(D) immune globulin (Z29.13), rabies immune globin (Z29.14), and fluoride administration (Z29.3). Notably, Z29.81 is designated for HIV pre-exposure prophylaxis, and Z29.89 can be used for other specified measures, including tuberculosis chemoprophylaxis. For situations where the specific preventive treatment is not detailed, Z29.9 applies. These codes help healthcare providers document and bill for preventative interventions accurately, supporting patients’ health by preventing future illness.
