Other protozoal diseases, not elsewhere classified (B60) ICD-10-CM
The B60 code range covers other protozoal diseases, not elsewhere classified with 15 ICD-10-CM diagnosis codes. 12 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.
