Drug codes appear here only when a CMS NDC–HCPCS crosswalk lists at least one of this drug’s NDC packages. CodeRx never assigns a code from the name or ingredient.

J-codes are permanent national codes for drugs and biologicals — most often clinician-administered (buy-and-bill) products paid under Medicare Part B — plus certain immunosuppressive, inhalation (via DME), and oral anticancer/antiemetic drugs. Units are reported in multiples of the dosage in the code descriptor.

Limitations and disclaimers
FDA NDC Directory data is submitted by labelers; FDA notes that inclusion does not mean the information was verified or that a product is approved, covered, or reimbursable.
HCPCS links are derived from CMS NDC–HCPCS crosswalks, which support ASP-based Part B payment and are not a complete list of billable NDCs.
Product class (brand, generic, biosimilar) is derived from the FDA marketing category and Purple Book license type, not from a commercial compendium.
Payment limits are Medicare Part B national limits; they do not reflect payer contracts, OPPS rates, 340B pricing, or acquisition cost.
Home infusion per diem S-codes are matched by therapy category from the FDA pharmacologic class and route, not from a CMS crosswalk. Payers choose which per diem codes they accept, and the right code can depend on the dosing schedule, infusion method, or daily volume.
Disclaimer. This application provides informational coding and reimbursement reference data. It does not constitute legal, clinical, coding, or billing advice. Codes, payment amounts, payer rules, and coverage policies can change. Verify all information with current CMS publications, the applicable payer, and your organization’s compliance policies before submitting a claim. CodeRx is not affiliated with or endorsed by CMS, FDA, Medicare, or any payer.

Derived calculationDrug-to-code links are aggregated from NDC-level CMS crosswalk rows.
Home infusion per diem (S-codes)
When a home infusion pharmacy dispenses this drug, the drug is billed with the code above and each day of pharmacy services, supplies, and equipment with a per diem S-code. CMS publishes no drug-to-per-diem crosswalk, so CodeRx picks the therapy category from the FDA pharmacologic class and route. S-codes are not payable by Medicare; confirm the code against the payer contract.

Washington Apple Health (Medicaid)
Not on HCA’s Home Infusion Therapy/Parenteral Nutrition Program fee schedule (effective Jul 1, 2026), so these per diems are not separately paid. Home infusion is paid with the supply, pump, and nutrition codes in that schedule instead (below).
Billing unit
1 unit = 1 day on service (the CMS descriptor ends “per diem”)
Who sets the rate
Each commercial plan’s contract or state Medicaid fee schedule. Some payers reduce a second per diem billed for the same day.
Billed separately
The drug, with its own HCPCS code and units, and nursing visits — the CMS descriptor says “drugs and nursing visits coded separately”.
Washington Apple Health (Medicaid) home infusion fee schedule — 59 codes, effective Jul 1, 2026
Washington Apple Health (Medicaid): Home Infusion Therapy/Parenteral Nutrition Program fee schedule, effective Jul 1, 2026
Maximum allowable fees as published by HCA, per billing unit of each code. BR = by report (invoice required); DP = covered under another program (see comments); N/A = no separate rate for that area. HCA pays the lesser of the provider’s usual charge and the maximum allowable fee (WAC 182-553).
How Medicare pays for home infusion instead
Medicare pays no per diem. Under its home infusion therapy services benefit, a qualified home infusion supplier is paid per infusion day, and only for drugs given through a Medicare-covered external infusion pump:
Category 1 — IV anti-infective, pain management, chelation, pulmonary hypertension, inotropic, or other IV drug (not chemotherapy): G0068, first visit G0088
Category 2 — Subcutaneous immunotherapy or other subcutaneous infusion: G0069, first visit G0089
Category 3 — IV chemotherapy or other highly complex drug: G0070, first visit G0090
Verification neededCodeRx links to coverage documents instead of copying them: CMS distributes their code lists under AMA, ADA, and AHA license terms that limit reuse. Medicare Advantage, Medicaid, and commercial plans set their own coverage and prior-authorization rules.
