Where these codes group
93 of the 115 codes in D37-D48 group to MMTA - Infectious Disease, Neoplasms, and Blood-Forming Diseases, but the range is not uniform — it spreads across 2 clinical groups. A further 17 are assigned no clinical group at all, which means a 30-day period cannot be grouped from them.
