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.

Naloxone hydrochloride is also indicated for the diagnosis of suspected or known acute opioid overdosage.
