Question: How would I report Wolff-Parkinson-White syndrome and nodal tachycardia?

Answer: For Wolff-Parkinson-White (WPW) syndrome, the ICD-10-CM index points you to I45.6 (Pre-excitation syndrome), which specifically lists WPW syndrome in a note with the code.

The index's entry for Tachycardia, nodal, lets you know to turn to I47.1 (Supraventricular tachycardia), which specifically lists nodal (paroxysmal) tachycardia.

Bonus tips: For I45.6, ICD-10 includes WPW along with these other conditions:

• Accelerated atrioventricular conduction
• Accessory atrioventricular conduction
• Anomalous atrioventricular excitation
• Lown-Ganong-Levine syndrome
• Pre-excitation atrioventricular conduction.

Along with nodal (paroxysmal) tachycardia, ICD-10 also includes the following conditions under I47.1:

• Atrial (paroxysmal) tachycardia
• Atrioventricular [AV] (paroxysmal) tachycardia
• Atrioventricular re-entrant (nodal) tachycardia [AVNRT] [AVRT]
• Junctional (paroxysmal) tachycardia.
