HCPCS code J2785: Regadenoson injection, per 0.1 mg2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for J2785 in California.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What J2785 covers

Regadenoson is an intravenous pharmacologic stress agent used to increase coronary blood flow during myocardial perfusion imaging. Nuclear medicine and cardiology teams commonly use it when a patient cannot achieve adequate exercise stress. The drug is administered as a rapid IV bolus; the usual adult dose is 0.4 mg, which corresponds to four J2785 units. The imaging and stress-test services are reported separately under their applicable codes.

CMS assigns J2785 physician fee schedule status E, meaning the drug is excluded from the physician fee schedule. When Medicare covers it, payment is handled under another method; CMS classifies it as a Part B drug and generally uses its quarterly ASP drug pricing files. Coverage is left to the Medicare contractor’s judgment. Report units based on the amount administered: each unit represents 0.1 mg of regadenoson.
