Question

A patient was admitted to the hospital with unstable angina that had been increasing in severity since the previous day. He was placed on best rest and telemetry and IV nitroglycerin was administered. An EKG showed paroxysmal tachycardia as well, so IV heparin was added to his medication program. His angina returned to normal status, and the tachycardia was not shown on repeat studies at the end of one week. Select the correct ICD-10-CM code(s) for this visit and provide the appropriate rationale.
