Why the study?
Does ICD-10-CM code assignment accurately identify outpatient anticoagulant-related bleeding among Medicare beneficiaries?
Does ICD-10-CM code assignment accurately identify outpatient anticoagulant-related bleeding among Medicare beneficiaries?
Relying solely on adverse effect or poisoning ICD-10-CM codes is insufficient for identifying anticoagulant-related bleeding in Medicare claims data, as it misses over 90% of cases.
Answers are grounded in this paper and cite their sources.
Adverse effect codes miss most anticoagulant bleeds in Medicare claims; leaves open validated algorithms for pharmacoepidemiologic research.
Performance of ICD-10-CM code assignments for bleeding among patients prescribed anticoagulants varied by bleed type and code position. Adverse effect/poisoning codes were not commonly used and would have missed over 90% of anticoagulant-related bleeding cases.
