Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Autoimmune hemophilia
- Autoimmune inhibitors to clotting factors
- Secondary hemophilia
Excludes1 inherited from the categories above D68.311
These are not written on D68.311, but they bind it: a note on a category applies to every code beneath it. Billing D68.311 with anything listed here is a denial.
Excludes2 inherited from the categories above D68.311
Also inherited, and the opposite of Excludes1: these conditions are not part of D68.311, but a patient can have both, so you may code both.
Other codes that can never be billed with D68.311
These codes carry an Excludes1 note pointing at D68.311. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D68.311 alone.
- R79.1Abnormal coagulation profile
Risk adjustment
D68.311 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- HCC 112 Immune Thrombocytopenia and Specified Coagulation Defects and Hemorrhagic Conditions0.450 RAF
Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
Medicare coverage
D68.311 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
