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

Billing references

What Med-Code can say about coding this product, and where each statement comes from. Nothing here is inferred from the name alone.

HCPCS codeNo match

No drug-specific HCPCS code in Med-Code's directory for this product. The directory is curated and not complete — check the current CMS HCPCS file before billing.

Administration

Drug administration (CPT 96360–96549)

When a clinician administers the drug, the administration is reported separately. Codes in this range cover hydration, therapeutic injections and infusions, and chemotherapy or other complex drug administration. The right code depends on route, duration and drug type, and self-administered drugs are not billed this way.
