What are the correct diagnosis and procedure codes for insertion of a permanent pacemaker with transvenous electrodes atrial and ventricular for sinoatrial node dysfunction?

The correct diagnosis code for sinoatrial node dysfunction is I49.5. The procedure code for the insertion of a permanent pacemaker with transvenous electrodes for both atrial and ventricular pacing is 33208 (for dual-chamber pacemaker insertion). If additional modifiers or specific circumstances apply, those should be included as necessary. Always verify with the latest coding guidelines to ensure accuracy.
