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 M90 Code Range

These bone conditions occur in diseases classified elsewhere. One group is osteonecrosis, another is osteitis deformans in neoplastic diseases, and a third is osteopathy in diseases classified elsewhere.

M90.5, M90.6, and M90.8 mark those groups. Each divides further by body site, with options for an unspecified site, another site, or multiple sites.
