Where these codes group

66 of the 82 codes in B00-B09 group to MMTA - Infectious Disease, Neoplasms, and Blood-Forming Diseases, but the range is not uniform — it spreads across 3 clinical groups. A further 1 are assigned no clinical group at all, which means a 30-day period cannot be grouped from them.
