Did You Know?

There are many new codes for Refractory Angina Pectoris as of October 1, 2022. For example:

  • Refractory Angina Pectoris, I20.2
  • CAD of Native Coronary Artery with Refractory Angina Pectoris, I25.112

Why Should You Care?

Refractory Angina has been designated as a Complication/Comorbidity. These new codes could impact the Severity of Illness for that admission. Refractory Angina Pectoris is a type of angina present in patients that have irreversible ischemia even though they have been treated with combinations of medications, PCI, or CABG. These patients are difficult to treat as they are already on multiple medications and surgical options would not be appropriate for the patient. In cases where the type of angina is not documented, knowing the types of antianginal medications will help with querying the physician to see if that patient was being treated for Refractory Angina Pectoris. Antianginal medications would be prescribed daily on a long-term basis and not just P.R.N.

Types of Antianginal Drugs with Examples:

  • Nitrites – Isosorbide Mononitrate, Nitroglycerin, Isosorbide Dinitrate
  • Beta-Blockers – Metoprolol, Carvedilol, Propanolol
  • Calcium-Channel Blockers – Diltiazem, Amlodipine, Verapamil
  • Metabolic Modulators – Ranolazine

It is important to note that codes for chronic conditions that are currently receiving treatment may be assigned even though symptoms may not be present for that admission.
