Clinical InformationClinical

  • Ectopic Atrial Tachycardia

    a disorder characterized by an electrocardiographic finding of atrial tachycardia that does not originate from the sinoatrial node.

  • Congenital Bundle of His Tachycardia|Congenital His Bundle Tachycardia|Junctional Ectopic Tachycardia, Congenital

    a congenital disorder characterized by an electrocardiographic finding of tachycardia that affects neonates and infants. it results from an increased automaticity in the atrioventricular node and his bundle.

  • Junctional Ectopic Tachycardia

    a tachycardia originating in or adjacent to the av junction.

  • Atrial Tachycardia

    a disorder characterized by an electrocardiographic finding of an organized, regular atrial rhythm with atrial rate between 101 and 240 beats per minute. the p wave morphology must be distinct from the sinus p wave morphology. (cdisc)

    a disorder characterized by a dysrhythmia with abrupt onset and sudden termination of atrial contractions with a rate of 150-250 beats per minute. the rhythm disturbance originates in the atria.

  • Paroxysmal Atrial Tachycardia|PAT|Paroxysmal atrial tachycardia|True Paroxysmal Atrial Tachycardia

Patient EducationClinical

Arrhythmia

An arrhythmia is a problem with the rate or rhythm of your heartbeat. Your heart beats too quickly, too slowly, or with an irregular pattern. Changes in the electrical signals that control your heartbeat cause arrhythmias.

Questions About I47.19Overview

Is I47.19 (Supraventricular tachycardia) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other supraventricular tachycardia on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does I47.19 group to?

When other supraventricular tachycardia is the principal diagnosis on an inpatient stay, it groups to MS-DRG 308, 309, 310, with relative weights from 0.5661 to 1.2040 depending on complications. Higher weights mean higher Medicare reimbursement.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
