You are the Revenue Cycle Coordinator for Anywhere Hospital. The Decision Support department at Anywhere Hospital is concerned because the volume of remittance advice remark code #M39 (The patient is not liable for payment for this service because the advance notice of non-coverage you provided the patient did not comply with program requirements.) on Medicare remittance advice logs has increased over the past three months. Further analysis of the denied claims shows that 75 percent of the claims have code 93798 (physician services for outpatient cardiac rehabilitation with continuous ECG monitoring) present. Therefore, they are requesting that the Revenue Cycle Team perform further investigation for this issue. After auditing the remittance advice logs and medical records for a sample of cardiac rehabilitation claims, the Revenue Cycle Team has determined that medical necessity is not being met for code 93798. Further, they have discovered that a new LCD was issued for code 93798 in October (three months ago). The ICD-10-CM diagnosis codes that support medical necessity for code 93798 are I20.1 Angina pectoris with documented spasm I20.8 Other forms of angina pectoris I20.9 Angina pectoris, unspecified I21.01 ST elevation (STEMI) myocardial infarction involving left main coronary artery I21.02 ST elevation (STEMI) myocardial infarction involving left anterior descending coronary artery I21.09 ST

(STEMI) myocardial infarction of anterior wall I22.1 Subsequent ST elevation (STEMI) myocardial infarction of inferior wall I22.2 Subsequent non-ST elevation (NSTEMI) myocardial infarction I22.8 Subsequent ST elevation (STEMI) myocardial infarction of other sites I22.9 Subsequent ST elevation (STEMI) myocardial infarction of unspecified site I25.10 Atherosclerotic heart disease of native coronary artery without angina pectoris I25.111 Atherosclerotic heart disease of native coronary artery with angina pectoris with documented spasm I25.118 Atherosclerotic heart disease of native coronary artery with other forms of angina pectoris I25.119 Atherosclerotic heart disease of native coronary artery with unspecified angina pectoris I25.2* Old myocardial infarction I25.5 Ischemic cardiomyopathy I25.6 Silent myocardial ischemia I25.701 Atherosclerosis of coronary artery bypass graft(s), unspecified, with angina pectoris with documented spasm I25.708 Atherosclerosis of coronary

autologous artery coronary artery bypass graft(s) with unspecified angina pectoris I25.731 Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with angina pectoris with documented spasm I25.738 Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with other forms of angina pectoris I25.739 Atherosclerosis of nonautologous biological coronary artery bypass graft(s) with unspecified angina pectoris I25.751 Atherosclerosis of native coronary artery of transplanted heart with angina pectoris with documented spasm I25.758 Atherosclerosis of

status Z98.89 Other specified postprocedural states **Note: ICD-10 code I25.2 (old myocardial infarction) refers to a MI that has occurred more than eight weeks prior to cardiac rehabilitation services. Further, around $20,790.00 has been written off due to ABNs not being issued for this cardiac rehabilitation service.
