Malignant neoplasm of other and ill-defined sites (C76) ICD-10-CM
The C76 code range covers malignant neoplasm of other and ill-defined sites with 14 ICD-10-CM diagnosis codes. 11 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.
