UHC student plan not 100% covered my annual physical exam

I have never been charged for my annual physical exam before. However, this time I am being asked to pay around $500 because some CPT codes were denied.

I contacted my insurance company, and they told me that the provider needs to resubmit the claim with the appropriate CPT and preventive screening diagnosis codes. I’m not sure whether this is a coding issue or if these tests are actually not covered under preventive care.

Has anyone experienced a similar issue?
