How the 11-digit form is made: The product segment has 3 digits, so one leading zero is added to it (5-3-2 → 5-4-2). Formatting the NDC does not by itself make it billable — the product, package and quantity must match what was dispensed or administered, and payer rules apply. Conversion rules

Indications (excerpt from the label)
INDICATIONS & USAGE Mexiletine hydrochloride capsules are indicated for the treatment of documented ventricular arrhythmias, such as sustained ventricular tachycardia, that, in the judgment of the physician, are life-threatening. Because of the proarrhythmic effects of mexiletine, its use with lesser arrhythmias is generally not recommended. Treatment of patients with asymptomatic ventricular premature contractions should be avoided. Initiation of mexiletine treatment, as with other antiarrhythmic agents used to treat life-threatening arrhythmias, should be carried out in the hospital. Antiarrhythmic drugs have not been shown to enhance survival in patients with ventricular arrhythmias.
