ICD-10 code for circulating anticoagulants

The ICD-10-CM code for circulating anticoagulants is D68.318 (Other hemorrhagic disorder due to intrinsic circulating anticoagulants, antibodies, or inhibitors). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on D68.318.

Within D68.31, choose D68.318 (Other hemorrhagic disorder due to intrinsic circulating anticoagulants, antibodies, or inhibitors) only when documentation doesn't support a more specific option: acquired hemophilia (D68.311) and Antiphospholipid antibody with hemorrhagic disorder (D68.312).

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.
