Schirmer Test CPT® code 95060 (Ophthalmic mucous membrane tests)

Hi again,

The insurance carriers deny payment if billed in conjunction with an E/M code (992-- ) as it is considered "bundled". However, if the chart notes indicate the purpose of this test is to determine ALLERGY, should they not pay?
How would you, in your opinion, code this - and what ICD-10 would suffice?

Also, how would the insurance carrier deny this if the assessment/impression may not result in an actual Allergy-related diagnosis, but it was ruled-out?

Thanks for your thoughts on this one.
