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.
- encounter for follow-up examination after completed treatment Z08 Z09
- encounter for aftercare following injury - code to Injury, by site, with appropriate 7th character for subsequent encounter
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 Z48 Code Range
The ICD-10 code Z48 covers encounters specifically for various types of postprocedural aftercare, addressing the follow-up care patients receive after surgeries or medical procedures.
This code section includes precise codes for care related to wound management, such as Z48.00 for "change of nonsurgical wound dressing done" and Z48.01 for "change of surgical wound dressing done." It also covers care involving suture removal (Z48.02) and drain management (Z48.03). Additionally, the codes identify aftercare following organ transplants, including heart (Z48.21), kidney (Z48.22), liver (Z48.23), and lung (Z48.24) transplants. There are also codes for aftercare related to surgery for neoplasms (Z48.3) and detailed surgical aftercare by body system, such as surgeries of the nervous system (Z48.811) or digestive system (Z48.815). Codes like Z48.89, synonymous with "surgical follow-up" or "postoperative visit," capture other specified surgical aftercare visits. These ICD-10 codes help medical coders accurately document and classify encounters focused on the care phase following medical or surgical interventions.
