Z codes are a special group of codes to indicate that a person with a resolving disease, injury or chronic condition is being seen for specific aftercare, such as the removal of internal fixation devices such as orthopedic pins. To indicate that a person is seen for the sole purpose of special therapy, such as chemotherapy, immunotherapy and radiation therapy. To indicate that a person not currently ill is encountering the health service for a specific reason, such as to act as an organ donor, encounter for medical observation for suspected diseases and conditions ruled out, administrative examinations (pre-employment exam, recruitment to armed forces), plastic and reconstructive surgery following medical procedures or healed injury (breast reconstruction following mastectomy). To indicate the birth status of newborns.
Key updates
An inside look into each interval of the ICD-10-CM code set
- These codes are used in any healthcare setting. Z codes may be used as either a first- listed or principal diagnosis code in the inpatient setting, or secondary code, depending on the circumstances of the encounter. Certain Z codes may only be used as first- listed or principal diagnosis in certain situations. Refer to Official Coding Guidelines for details.
- Z codes are not procedure codes. A corresponding procedure code must accompany a Z code to describe any procedure performed.

Includes:
The word 'Includes' appears immediately under certain categories to further define, or give examples of, the content of the category.
Excludes Notes:
The ICD-10-CM has two types of excludes notes. Each note has a different definition for use but they are both similar in that they indicate that codes excluded from each other are independent of each other.
Excludes Notes:
The ICD-10-CM has two types of excludes notes. Each note has a different definition for use but they are both similar in that they indicate that codes excluded from each other are independent of each other.
Excludes1:
A type 1 Excludes note is a pure excludes. 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.
Excludes2:
A type 2 excludes note represents 'Not included here'. An excludes2 note indicates that the condition excluded is not part of the condition it is excluded from 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.

Code First/Use Additional Code notes (etiology/manifestation paired codes)
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a 'use additional code' note at the etiology code, and a 'code first' note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
In most cases the manifestation codes will have in the code title, 'in diseases classified elsewhere.' Codes with this title are a component of the etiology/ manifestation convention. The code title indicates that it is a manifestation code. 'In diseases classified elsewhere' codes are never permitted to be used as first listed or principal diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.
Code Also
A code also note instructs that 2 codes may be required to fully describe a condition but the sequencing of the two codes is discretionary, depending on the severity of the conditions and the reason for the encounter.
7th characters and placeholder X
For codes less than 6 characters that require a 7th character a placeholder X should be assigned for all characters less than 6. The 7th character must always be the 7th character of a code
