Wiki Coding ACS and or/unstable angina

[donformica]

Hi,

I am a coding student and am confused by code 411.1.
Is this always coded with 414.xx or only if there is an established (documented) CAD?

Thanks,

Don

I found the following information in response to your question:

Acute coronary syndrome and unstable angina are both coded as ICD-9-CM code 411.1. When the principal diagnosis is acute coronary syndrome in a patient with established coronary artery disease, the coder must report coronary artery disease as a principal diagnosis with a secondary diagnosis of unstable angina to comply with the 2009 Official Guidelines for Coding and Reporting of Diagnoses for an inpatient claim.

I hope this helps.
