D69.1 — Qualitative platelet defects
D69.1 is a billable, specific ICD-10-CM code for qualitative platelet defects. It is valid for submission on a claim.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- hemolytic-uremic syndrome (D59.3-)
Excludes2 — not included here, but may coexist
The excluded condition is not part of this code, but a patient can have both. You may code both.
- von Willebrand disease (D68.0-)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Bernard-Soulier [giant platelet] syndrome
- Glanzmann's disease
- Grey platelet syndrome
- Thromboasthenia (hemorrhagic) (hereditary)
- Thrombocytopathy
Excludes1 inherited from the categories above D69.1
These are not written on D69.1, but they bind it: a note on a category applies to every code beneath it. Billing D69.1 with anything listed here is a denial.
Written on D69 — Purpura and other hemorrhagic conditions
Other codes that can never be billed with D69.1
These codes carry an Excludes1 note pointing at D69.1. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading D69.1 alone.
- R23.3Spontaneous ecchymoses
Risk adjustment
D69.1 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
D69.1 is named in 2 Medicare coverage policies — 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.

How D69.1 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to D69.1.

- Diacyclothrombopathia
