Question: How should I report Wolff-Parkinson-White syndrome and nodal tachycardia under ICD-10-CM?

Answer: For the Wolff-Parkinson-White (WPW) syndrome, you should report I45.6 (Pre-excitation syndrome). Under ICD-9-CM, you report this using 426.7 (Anomalous atrioventricular excitation).

Bonus tip: Code I45.6 also covers Lown-Ganong-Levine syndrome, which you now report using 426.81 (Lown-Ganong-Levine syndrome). So even though you use different codes for WPW and Lown-Ganong-Levine under ICD-9, you use the same code for both under ICD-10.

The ICD-10 code for nodal tachycardia is I47.1 (Supraventricular tachycardia). Under ICD-9, you use 427.89 (Other specified cardiac dysrhythmias), according to the ICD-9 index. Or if the diagnosis is nonparoxysmal atrioventricular nodal tachycardia, you should use 426.89 (Other specified conduction disorders).
