COMPARING TEST DATA FROM PREVIOUS VISIT

MODIFIER JW FOR UNUSED MEDICATION

It is advisable to check individual payer policies for specific reporting instructions. Not all payers recognize the JW modifier, and some require that you provide additional information such as the product's National Drug Code (NDC) and NDC units (which are often different from HCPCS drug units). Some plans also require that you consider the smallest available drug unit that would provide the required dose of medication with the least waste. For example, Drug A is available in 30 mg or 60 mg single-use vials. You administer 20 mg and report 10 mg as wasted by appending modifier JW even though you provided it from a 60 mg single-use vial.
