Final answer:
Established E/M codes are used in healthcare settings for patient visits related to specific medical conditions or routine follow-ups. ICD codes are used to identify and classify diagnoses in healthcare.
Step-by-step explanation:
Established E/M codes are primarily used in healthcare settings to document and bill for patient visits. These codes are used when a patient seeks treatment for a particular medical condition or for routine follow-up visits. For example, a patient with diabetes may schedule regular appointments with their primary care physician to monitor their condition and adjust their treatment plan accordingly. In this case, the physician would use an established E/M code to indicate that this is an ongoing visit related to the patient's existing condition.
Another example is when a patient is receiving regular chemotherapy treatments for cancer. Each visit to the oncologist would be coded as an established E/M code because it is a continuation of the patient's ongoing treatment.
ICD codes are commonly used in healthcare to identify and classify specific diagnoses. Two locations where you would likely find an ICD code are on a patient's medical chart and on insurance claims forms submitted for reimbursement.
