Where these codes group

82 of the 85 codes in B65-B83 group to MMTA - Infectious Disease, Neoplasms, and Blood-Forming Diseases, but the range is not uniform — it spreads across 2 clinical groups. A further 2 are assigned no clinical group at all, which means a 30-day period cannot be grouped from them.
