ICD-10 code for blood clotting mechanism disturbance

The ICD-10-CM code for blood clotting mechanism disturbance is D68.9 (Coagulation defect, unspecified).

Within D68, choose D68.9 (Coagulation defect, unspecified) only when documentation doesn't support a more specific option: von Willebrand disease (D68.0), hereditary factor XI deficiency (D68.1), hereditary deficiency of other clotting factors (D68.2), hemorrhagic disorder due to circulating anticoagulants (D68.3), acquired coagulation factor deficiency (D68.4), primary thrombophilia (D68.5), other thrombophilia (D68.6) and other specified coagulation defects (D68.8).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 813 (Coagulation Disorders, relative weight 1.5257), in MDC 16 (Diseases and Disorders of the Blood and Blood Forming Organs and Immunological Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
