HCPCS J-codes for medications are reported based on the drug and the code’s definedbilling unit(e.g., mg per unit).Ondansetronis reported withJ2405, which is typically defined per1 mg(so 2 mg is reported as2 units→ J2405 × 2).Ketorolac tromethamineis reported withJ1885, commonly defined per15 mg(so a 15 mg dose is1 unit→ J1885). Option A matches this unit logic:J2405 × 2for 2 mg ondansetron, plusJ1885for 15 mg ketorolac. Option B incorrectly multiplies ketorolac by 15 units, which would overstate the dose because the code unit is not 1 mg in this context. Option C underreports ondansetron units if the unit is 1 mg. Option D uses an incorrect J-code for ketorolac. CPC exam tip: always read theJ-code unit definitionand convert the administered dose into billable units accurately.
