Where these codes group
125 of the 150 codes in H49-H52 group to MMTA - Other. A further 25 are assigned no clinical group at all, which means a 30-day period cannot be grouped from them.
Code families in H49-H52
One page per three-character family: every code in it, whether it can lead a claim, its clinical group and comorbidity subgroup.
