What Medicare pays for Neulasta (2026 Q2)

Once a claim carries a covered diagnosis, Medicare Part B reimburses the drug at the ASP + 6% payment limit. Current allowed amounts per billing unit:

HCPCS	Description	Per unit	Allowed (ASP + 6%)
J2506	Inj pegfilgrast ex bio 0.5mg	0.5 mg	$127.379

Source: CMS ASP Drug Pricing File, 2026 Q2. Payment = ASP + 6% per unit; multiply by units billed (watch JZ/JW wastage). Your patient's share is typically 20% after the deductible. Estimate the full cost & patient out-of-pocket →

Neulasta is a physician-administered biologic billed under Medicare Part B (not the Part D pharmacy benefit). Under Part B, Medicare pays the practice for the drug (HCPCS J2506) plus its administration — but only when the claim's diagnosis (ICD-10) code supports medical necessity. Each MAC publishes the specific covered diagnoses in a Billing & Coding Article; a claim with a diagnosis outside that list is typically denied as not medically necessary (CO-50).

How to use this list when billing

Put a medically necessary, FDA-indicated diagnosis from the list above on the claim line with J2506, match the correct product code and units (check JZ/JW wastage), and document medical necessity. Because there's no drug-specific LCD, coverage is judged per medical necessity by your MAC; an off-label use can still be covered if supported by an approved drug compendium.

LCD vs. Billing & Coding Article vs. NCD

An LCD (Local Coverage Determination) is a MAC's policy on whether a service is reasonable and necessary in its region, and its companion Billing & Coding Article holds the covered ICD-10 and HCPCS code lists. A NCD (National Coverage Determination), where one exists, applies nationwide. Neulasta has no drug-specific LCD or Article, so there is no published covered-code list — it's covered under the general Part B drug benefit per medical necessity, and the FDA-approved indications above are the practical starting point.

Common Neulasta denial reasons

What you see	Why	Fix
CO-50 — not medically necessary	Diagnosis the MAC doesn’t accept as medically necessary	Bill a medically necessary FDA-indicated diagnosis from the list above; document necessity (compendium cite for off-label)
Diagnosis/units mismatch	Right dx but wrong product code or unit count	Match the J/Q code and units to the drug actually given (check JZ/JW wastage)
Off-label denial	Indication isn't FDA-labeled and isn't compendium-supported	Cite an approved compendium (e.g. DrugDex/NCCN) or appeal with literature
Self-administered (SAD) denial	Drug is on your MAC's self-administered exclusion list	Check the SAD list — it may be Part D, not Part B
