Find information on High-Grade AV Block including diagnosis, treatment, and prognosis. Learn about second-degree atrioventricular block type 2 and third-degree heart block, complete heart block symptoms, ECG findings, and medical coding guidelines for accurate clinical documentation. Explore resources for healthcare professionals on managing high-grade atrioventricular block and relevant ICD-10 codes.
Also known as
Atrioventricular block, complete
Complete heart block where atria and ventricles beat independently.
Atrioventricular block, other and unspecified
Includes high-grade AV block not further specified.
Other specified conduction disorders
May include high-grade AV block in specific contexts.
Second degree atrioventricular block
Mobitz II second-degree block can be considered high-grade.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the AV block documented as high-grade?
When to use each related code
| Description |
|---|
| High-grade AV block |
| Second-degree AV block Mobitz I |
| Third-degree AV block (Complete) |
Coding high-grade AV block without specifying second or third degree may lead to inaccurate DRG assignment and lost revenue.
Failing to code the underlying etiology (e.g., MI, Lyme disease) impacts risk adjustment and quality reporting.
Inaccurate coding for pacemaker or ICD implantation related to AV block can cause claims denials and compliance issues.
Patient presents with symptoms suggestive of high-grade atrioventricular (AV) block. Presenting complaints include dizziness, lightheadedness, syncope, presyncope, fatigue, shortness of breath, and chest pain. Electrocardiogram (ECG or EKG) findings reveal advanced AV block, demonstrating second-degree AV block Mobitz type II or third-degree AV block (complete heart block). The patient's heart rate is documented as bradycardia, with a rate below the normal sinus rhythm range. Symptoms are consistent with decreased cardiac output and impaired perfusion. Differential diagnosis includes sinus bradycardia, sick sinus syndrome, and other conduction system abnormalities. Risk factors for high-grade AV block such as ischemic heart disease, myocardial infarction, cardiomyopathy, myocarditis, electrolyte imbalances, and drug toxicity have been considered and evaluated. Treatment plan includes continuous cardiac monitoring, assessment for pacemaker implantation, and management of underlying medical conditions. Patient education provided on symptoms, medications, and follow-up care. ICD-10 code I44.2 (Atrioventricular block, complete) or I44.1 (Atrioventricular block, second degree) is assigned, depending on the specific type of AV block documented. Medical billing and coding procedures adhered to. Prognosis and long-term management discussed with the patient, emphasizing the importance of regular cardiology follow-up.
