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

79 of the 88 codes in K80-K87 group to MMTA - Gastrointestinal tract and Genitourinary system, but the range is not uniform — it spreads across 2 clinical groups. A further 6 are assigned no clinical group at all, which means a 30-day period cannot be grouped from them.
