Revenue code 0636
Drugs requiring detailed coding
The revenue code for drugs that carry their own HCPCS code, which in practice means the expensive ones: infused biologics, chemotherapy, contrast agents, certain injectables. Each line should show the drug's J-code and the number of units.
Where this line goes wrong
Units are the trap
J-codes are billed in small dose units (for example per 10 mg). A drug given once can legitimately show 50 units, but a wrong unit count multiplies a large charge. Check the dose given against the units billed.
Wastage
Hospitals may bill the unused part of a single-use vial with a modifier (JW). It is allowed, but the wasted amount should be documented and should not exceed the vial size.
Check it, then ask
- 1
Ask for the medication administration record and compare the dose given with the units billed for each J-code.
- 2
Look for JW (wastage) lines and check the documented waste.
- 3
Compare the charge per unit with the Medicare average sales price for the same J-code if you want a reference point.

Why is contrast dye a separate charge?
Contrast for a CT or MRI is billed under 0636 with its own code, in addition to the scan. It is legitimate; check the units against the amount actually given.

It is not a coding, legal or medical opinion about your bill, and the code descriptions are mediloop's own plain-English summaries, not the official CPT descriptors, which are owned by the American Medical Association. Whether a charge was correct depends on the record of your visit and your payer's rules.
