I work for a genetics lab and we are having difficulties with Medicare and which modifier to use when multiple genes are being billed under 81479.
Here are 3 scenarios
• Scenario 1—if we do bill with a Z code for an unlisted code (81479) multiple times for a different gene do we use 59 or 91?
• Scenario 2—If we bill with a Z code for an unlisted code (81479) multiple times for a different gene and want to show different units for that gene on the same claim and date of service, should we bill individual genes with 59 or 91?
• Scenario 3--Can we bill 59 and 91 on the same claim?
I have posted other questions in this forum but have not gotten any feed back. Any help would be appreciated.
