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 Z46 Code Range
The ICD-10 code Z46 section defines codes used for medical visits involving the fitting and adjustment of various devices. These codes cover a broad range of devices, helping healthcare providers document encounters centered on ensuring medical devices fit correctly and function properly.
This section includes codes for adjusting common assistive devices such as spectacles and contact lenses (Z46.0), hearing aids (Z46.1), and dental prosthetic devices (Z46.3). For example, dental prosthetics adjustments, also known as fitting maxillofacial prostheses, correspond with Z46.3. Orthodontic devices, including retainers, fixed and removable appliances, fall under Z46.4, covering conditions like requiring upper or lower orthodontic appliances. More specialized devices, such as gastric lap bands (Z46.51), insulin pumps (Z46.81), and urinary devices (including catheter repositioning, Z46.6), are also specified. Additionally, other unspecified or less common devices are captured through codes like Z46.8 and Z46.9. These ICD-10 codes play a crucial role in documenting patient encounters focused solely on the adjustment or fitting of medical devices and appliances.
