Other disorders of blood and blood-forming organs in diseases classified elsewhere
In Other disorders of blood and blood-forming organs (D70-D77), chapter 3: Diseases of the Blood and Blood-Forming Organs
- D77 is billable and valid on claims for FY 2027. If the record has more detail, check the other codes under D70-D77 below.
- As a secondary diagnosis it is not a CC or MCC, so it doesn't raise the MS-DRG payment.
- Doesn't count toward a Medicare Advantage risk score (no HCC in V28).
- AHRQ's Chronic Condition Indicator classes it as not chronic (an acute or short-term condition).
- Can't be the principal diagnosis: code the underlying condition first. (Manifestation list)

Blood Disorders
Your blood is living tissue made up of liquid and solids. The liquid part, called plasma, is made of water, salts and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells and platelets.
