Encounter for other prophylactic measures (Z29) ICD-10-CM
The Z29 code range covers encounter for other prophylactic measures with 11 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
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

Z29.3 identifies fluoride administration. Z29.8 groups other specified measures, separating HIV pre-exposure prophylaxis from other specified measures. Z29.9 identifies unspecified preventive measures.
