Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- removal or replacement of implanted device
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.
- malfunction or other complications of device - see Alphabetical Index
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the Z45 Code Range
The ICD-10 code Z45 series is used to document healthcare encounters focused on the adjustment and management of various implanted medical devices. These codes capture care related to devices ranging from cardiac pacemakers to hearing implants and infusion pumps.
Specifically, Z45.0 covers encounters for cardiac devices like pacemakers (Z45.01, including battery checks at elective replacement timing) and implantable defibrillators (Z45.02). Encounters for managing infusion pumps and vascular access devices are coded as Z45.1 and Z45.2, respectively. Special senses devices, including visual substitution and hearing implants such as cochlear devices, fall under Z45.3 and subcodes like Z45.321. Nervous system implants, including neurostimulators and cerebrospinal fluid drainage devices, are documented with Z45.4 codes. Breast implant adjustments or removals are represented by Z45.81 and more specific right or left breast implant codes. This ICD-10 code section helps healthcare professionals precisely record visits related to implanted device management, ensuring clarity in patient care documentation.
