No clinical group

A period cannot be grouped from these.

Barred as primary

CMS rejects these in the primary position.

Where these codes group

212 of the 300 codes in N80-N98 group to MMTA - Other, but the range is not uniform — it spreads across 2 clinical groups. A further 29 are assigned no clinical group at all, which means a 30-day period cannot be grouped from them.
