286.9
ICD-9-CMThis code represents a broad category of disorders affecting the blood's ability to clot properly, stemming from deficiencies or dysfunctions of coagulation factors that are not otherwise specified or are less common. It encompasses conditions where the precise cause of a bleeding or clotting tendency is unknown or falls outside more specific diagnostic categories.
This code is appropriate for documenting coagulation defects when the specific type of deficiency (e.g., Factor VIII, Factor IX) has not been definitively diagnosed, or when the defect is due to a rare or unclassified coagulation factor abnormality. It is supported by documentation indicating abnormal coagulation studies (e.g., prolonged PT, aPTT, bleeding time) without a specific underlying cause identified.
