icd codes for cad
Coding CAD. The ICD-9-CM diagnosis codes for CAD are classified to subcategory 414.0x. Coding CAD requires documentation of the coronary artery involved and whether or not it is of a native artery, an artery of a transplanted heart, or a bypass graft. The fifth-digit subclassification identifies the coronary artery involved.
Documentation specificity under the ICD-10-CM system for coronary artery disease (CAD) with and without angina is crucial for accurate classification of these disease processes. Combination codes including CAD with and without angina will exist under the new coding system.
