What This Code Means

A condition where platelets don't function properly even though the count is normal, leading to increased bleeding and bruising.

Coding Tips

• •Verify the platelet count is normal or near-normal to distinguish from thrombocytopenia
• •Document the specific type of qualitative defect if identified (e.g., Glanzmann thrombasthenia, Bernard-Soulier syndrome)

Clinical Significance

Qualitative platelet defects encompass a group of inherited and acquired conditions where platelet number is normal but platelet function is impaired, leading to mucocutaneous bleeding. Examples include Glanzmann thrombasthenia (glycoprotein IIb/IIIa deficiency), Bernard-Soulier syndrome (glycoprotein Ib/IX/V deficiency), and storage pool diseases. These conditions cause prolonged bleeding time and abnormal platelet aggregation studies.

Documentation Requirements

• ✓Document the specific platelet function defect identified through aggregation studies, flow cytometry, or genetic testing.
• ✓Record platelet count (which is characteristically normal), bleeding time or PFA-100 closure times, and specific aggregation abnormalities (ristocetin, ADP, collagen, epinephrine).
• ✓Note whether the condition is inherited or acquired.
