Codes in range

No clinical group

A period cannot be grouped from these.

Barred as primary

CMS rejects these in the primary position.

Where these codes group

43 of the 67 codes in K90-K95 group to MMTA - Gastrointestinal tract and Genitourinary system, but the range is not uniform — it spreads across 3 clinical groups. A further 5 are assigned no clinical group at all, which means a 30-day period cannot be grouped from them.
