Can you report EM codes if the service is unrelated to dialysis?

Yes. Evaluation and management (E/M) codes 99201-99215 can be reported for services provided to dialysis patients even if the service is unrelated to dialysis. These codes are used to report outpatient office or other outpatient visits when the patient has an established medical condition that requires a moderate complexity medical decision-making. The code selection should be based on the time and complexity of the visit, regardless of whether the service is related to dialysis or not.
