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

69 of the 85 codes in N30-N39 group to MMTA - Gastrointestinal tract and Genitourinary system, but the range is not uniform — it spreads across 2 clinical groups. A further 8 are assigned no clinical group at all, which means a 30-day period cannot be grouped from them.
