Coronary artery disease (CAD) develops when the arteries that supply the blood to the heart muscles become hardened and narrowed due to a buildup of cholesterol and other materials, such as plaque, on their inner wall. It's also called atherosclerosis.
Coding tells a patient's story, based on the narrative the physician provides in his or her documentation. Accurately painting a picture of the patient's severity of illness (SOI) and risk of mortality (ROM) is essential for good patient care, and it is becoming increasingly important for quality measures and payment.
Many coders and CDI specialists memorized previous Official Guidelines for Coding and Reporting , Coding Clinic for ICD-9-CM and do not have to give them a lot of forethought before applying correctly to their day-to-day reviews. Although many of the Official Guidelines for Coding and Reporting remain the same in ICD-10, none of Coding Clinic's previous advice can be applied to the new code set. Without years of new Coding Clinic advice under their belts, it may take some time before the staff exhibits the same ease when applying ICD-10-CM/PCS codes to the documentation provided.
Coding professionals may inappropriately assign codes from parts of the medical record where the doctors, early in the workup of a complex patient, were describing differential diagnoses in their evaluation of the patient. Robert S. Gold, MD, discusses whether coders should report every diagnosis mentioned in a patient’s chart.
