Medical Billing Tips – Coding for Medicare Flu Shots

October 19, 2019

Hi my name is Manny Oliverez, Director of Operation at
Capture Billing. You medical billers know how to bill flu shots but what you may not know is that on January 1, 2011 CMS Medicare changed the rules. No longer do you bill Medicare patients with CPT code 90658 for the flu shot. Now there’s a whole new set of codes. So for example, what happens when your Medicare patient comes in for their flu shot. Well, no longer are you going to be using CPT code 90658. Now you have to use Medicare Q Codes Q2035 or Q2036, Q2037 Q2038 Q2039 Why can’t we use these codes anymore? Because Medicare and the federal government now
want to know exactly what is being injected into this patient’s arm. These codes are brand specific. Each one of these is a different manufacture of influenza vaccine. So now by
reporting the Q Codes you are reporting to Medicare
exactly what brand of vaccine you use to give to the
Medicare patient. Now for more information on this you can do a Google search on CMS, Medicare, Q Codes or go to the CMS website or to your local CMS carrier As always remember, a medical practice is a business, treat as such, doing anything else,
