Simplified Billing for Influenza, Pneumococcal and COVID-19 Virus
10.3.2.1 - Simplified Billing for Influenza, Pneumococcal and COVID-19 Virus
Vaccination Services by HHAs
(Rev. 11355; Issued:04-14-22; Effective:05-16-22; Implementation:05-16-22)
The following billing instructions apply to HHAs that roster bill for influenza virus and
pneumococcal vaccines.
•
When an HHA provides the influenza virus vaccine or the pneumococcal vaccine in a mass
immunization setting, it does not have the option to pick and choose whom to bill for this
service. If it is using employees from the certified portion, and as a result will be reflecting
these costs on the cost report, it must bill the A/B MAC (HHH) on the Form CMS-1450.
•
If the HHA is using employees from the noncertified portion of the agency (employees of
another entity that are not certified as part of the HHA), and as a result, will not be
reflecting these costs on the cost report, it must obtain a provider number and bill their A/B
MAC (B) on the Form CMS-1500.
•
If employees from both certified and noncertified portions of the HHA furnish the vaccines
at a single mass immunization site, they must prepare two separate rosters, e.g., one for
employees of the certified portion to be submitted to the A/B MAC (HHH) and one roster
for employees of the noncertified portion to be submitted to the A/B MAC (B).
