Hi, I'm trying to figure out how to code Atrial Fibrillation with Rapid Ventricular Response in ICD-10. What would the code be for RVR? Or should I just code the unspecified atrial fib only - I48.91? Thanks, Kim, Atrial fibrillation, also known as AFib, is a condition where the heart’s upper chambers beat erratically, causing an irregular and often rapid heartbeat. I4901 specifically indicates AFib with rapid ventricular response., became effective on October 1, 2021. This is the American ICD-10-CM version of R65. What is the drug of choice for atrial fibrillation? There are 3 goals in the management of AF: control of the ventricular rate, minimization of thromboembolism risk (particularly stroke), and restoration and maintenance of sinus rhythm., ICD-10 codes for this scenario would be: I48.91 – Atrial fibrillation unspecified. E78.00 – High cholesterol. I10 – Hypertension. Note: Afib with rapid ventricular response (RVR) should be coded as unspecified afib. Peter, 67 year old male presents to emergency department with palpitations, shortness of breath and fatigue from past 10 days., AFIB ICD 10 code is I48.0. In 2022, the ICD 10 CCs (complications/comorbidities) list was expanded to include chronic, permanent, persistent, and long-term permanent AF. A confirmed diagnosis of persistent atrial fibrillation in an inpatient setting is necessary. I48 is the ICD 10 code for atrial fibrillation and flutter., ICD-10-CM Diagnosis Code I48.91 [convert to ICD-9-CM] Unspecified atrial fibrillation Atrial fibrillation; Atrial fibrillation with rapid ventricular response.
