Specific code 2015 ICD-9-CM Diagnosis Code 426.7
Anomalous atrioventricular excitation
  • 2015
  • Billable Thru Sept 30/2015
  • Non-Billable On/After Oct 1/2015

  • ICD-9-CM 426.7 is a billable medical code that can be used to indicate a diagnosis on a reimbursement claim, however, 426.7 should only be used for claims with a date of service on or before September 30, 2015. For claims with a date of service on or after October 1, 2015, use an equivalent ICD-10-CM code (or codes).
Convert to ICD-10-CM: 426.7 converts approximately to:
  • 2015/16 ICD-10-CM I45.6 Pre-excitation syndrome
Approximate Synonyms
  • ANOMALOUS ATRIOVENTRICULAR EXCITATION
  • Anomalous AV excitation
  • Wolff Parkinson White syndrome
  • Wolff-Parkinson-White pattern
Clinical Information
  • A type of ventricular pre-excitation resulting from the activation of an accessory pathway known as the bundle of kent. This pathway presents an abnormal electrical communication from the atria to the ventricles. Wolff-parkinson-white syndrome is characterized by a short pr interval and a long qrs interval with a delta wave. (nci)
  • Association of paroxysmal tachycaria or atrial fibrillation and pre-excitation characterized by a short pr interval and a long qrs interval with a delta wave
Applies To
  • Atrioventricular conduction:
    • accelerated
    • accessory
    • pre-excitation
  • Ventricular pre-excitation
  • Wolff-Parkinson-White syndrome

ICD-9-CM codes are used in medical billing and coding to describe diseases, injuries, symptoms and conditions. ICD-9-CM 426.7 is one of thousands of ICD-9-CM codes used in healthcare. Although ICD-9-CM and CPT codes are largely numeric, they differ in that CPT codes describe medical procedures and services. Can't find a code?
