• I49.8 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
• The 2023 edition of ICD-10-CM I49.8 became effective on October 1, 2022.
• This is the American ICD-10-CM version of I49.8 - other international versions of ICD-10 I49.8 may differ.

• Atrioventricular (av) tachycardia (fast heart beat)
• Atrioventricular junctional heart rhythm
• Atrioventricular nodal re entrant tachycardia
• Av junctional rhythm
• Junctional escape beats
• Postural orthostatic tachycardia syndrome
• Re-entrant atrioventricular node tachycardia
• Re-entrant atrioventricular tachycardia

• A derangement in the normal functioning of the sinoatrial node. Typically, sa node dysfunction is manifest as sinoatrial exit block or sinus arrest, but may present as an absolute or relative bradycardia in the presence of a stressor. It may be associated with bradycardia-tachycardia syndrome
• A derangement in the normal functioning of the sinoatrial node. Typically, sa node dysfunction is manifest as sinoatrial exit block or sinus arrest, but may present as an absolute or relative bradycardia in the presence of a stressor. It may be associated with bradycardia-tachycardia syndrome.
• An arrhythmia originating from within the atrioventricular node.
