Ob-Gyn Coding Alert

Double check your code assignments to make sure you comply with payer instructions.

Flu season can be a busy time in the emergency department, especially if an epidemic hits the area. Although ideally not the place for preventive care, your ob-gyn may provide flu shots for certain patient populations that seek treatment there. To better recoup deserved reimbursement for these services, take note of the differences between CPT® and Medicare for flu vaccine codes.

CPT® has several codes describing administration of influenza virus vaccine depending on the formula of the vaccine, method of administration, and age of the patient.

For example, the variables of "split virus" and "preservative free" and "pandemic formula H1N1" are used to differentiate codes describing specific vaccinations.

Tip: Watch for intramuscular as opposed to intranasal or intradermal delivery in the notes to select the code that accurately describes the service provided.

Administration: Remember that vaccine administration requires a different CPT® code than regular therapeutic injections. For flu vaccines, the code will most likely be 90471, Immunization administration (includes percutaneous, intradermal, subcutaneous, or intramuscular injections); 1 vaccine (single or combination vaccine/toxoid) or 90473, Immunizaton administration by intranasal or oral route; 1 vaccine (single or combination vaccine/toxoid).

Medicare Has its Own Codes

Medicare has its own G code, G0008 (Administration of influenza virus vaccine), to use in place of the CPT® code alternatives describing administration of the vaccine.

CMS also created a set of Q codes to differentiate the brand of vaccine in use in order to base payment accordingly.

Those codes along with the pricing as of Oct. 1, 2011 are as follows:

• Q2035 (Afluria). The national limit is $11.543.
• Q2036 (Flulaval). The national limit is $8.784
• Q2037 (Fluvirin). The national limit is $13.652.
