J-codes identify drugs a clinician administers rather than a patient self-administers. Each code carries a billable unit, and the unit — not the milligram dose — is what goes on the claim.
A J-code says what drug was given; a CPT code says how it was given. Divide the dose administered by the code’s billable unit to get the quantity to report — 440 mg of a drug coded at 10 mg = 1 unit is 44 units, not 440.
