Which Code is the Right Code for 2017 Flu Vaccines?

Coding Tips for Flu VaccinesRecent CDC recommendations state that vaccination efforts should begin as soon as the seasonal flu vaccines are available and continue through the flu season.  While administering the flu vaccine may be easy, coding and getting paid for it is not.

Flu vaccines are no longer easy to code due primarily to the vast number of vaccines available.  It puts the onus on the provider to know which code goes with which vaccine.  It seems like every year there are changes on how to code flu vaccines.  This year was no different.

2017 Changes

First, there was the January 1 revision.  This changed many of the influenza CPT code descriptions, removed the age indicator and added dosage.  And, it was recently announced that effective July 1, 2017 the new CPT 90682 will be reimbursed by Medicare.  This is specific to the influenza virus vaccine quadrivalent (RIV4) derived from recombinant DNA, hemagglutinin (HA) protein only, preservative and antibiotic free for intramuscular use.  Medicare carriers have until August 1, 2017 to implement the CPT and pay from service dates starting July 1, 2017.

What Codes for Flu Vaccines?

When a flu vaccine is given, the provider should also enter CPT 90471 for commercial or G0008 for Medicare, for the administration of the vaccine.  The ICD10 DX code is Z23.  Just to confuse the issue even further coding is specific to trade name, how supplied, mercury content and age group.  The Immunization Action Coalition, published a table of flu vaccines by trade name to assist you in selecting the proper CPT code for Commercial and Medicare carriers.

Pricing

The Medicare Part B payment allowance for seasonal flu vaccines are 95% of the average wholesale price.  Patient deductible and coinsurance amounts do not apply for the vaccine.  All providers who administer the vaccine must take assignment on the claim for the vaccine.  The CMS Seasonal Influenza Vaccines Pricing page lists the payment allowances for the 2016-2017 flu season.
