About this chapter
ICD-10-CM Chapter III — “Diseases of the blood and blood-forming organs and certain disorders involving the immune mechanism” — spans every category from D50 through D89. Each category in that range expands into a header code and one or more billable codes with additional specificity (laterality, episode of care, or clinical detail). Open any code’s own page to see its exact position in the hierarchy, its parent and children, and whether it’s billable.
