Disorders due to Intrinsic Circulating Anticoagulants, Antibodies or Inhibitors
Effective October 1, 2011, code 286.5, Hemorrhagic disorder due to intrinsic circulating anticoagulants, has been expanded because the code included a number of diverse disorders which are characterized by an abnormally elevated activated partial thromboplastin time (aPTT) despite different physiology. Code 286.52, Acquired hemophilia, was created to distinguish the acquired form of hemophilia from congenital hemophilia.

Article Overview
This article covers ICD-9-CM revisions for hemorrhagic disorders associated with intrinsic circulating anticoagulants, antibodies, or inhibitors. It is relevant to coding professionals, auditors, compliance staff, and clinicians who need to understand how these diagnoses were reorganized and what related categories are discussed. The article also notes related hypercoagulable and nonspecific immunologic findings that are referenced alongside the revised hemorrhagic disorder codes.
Why This Topic Matters
These changes affect diagnosis classification and the way related hematologic and autoimmune conditions are grouped in ICD-9-CM. Understanding the scope of the revision helps support accurate documentation review and code assignment in settings where these disorders are encountered.
