Good morning,

Good morning,

I am so stumped as to what would be the appropriate code for a physician to bill for the following scanario. Hope you can help!

"I am interpreting transmission electron microscopy images (approximately 20 per patient) of nasal biopsies (ciliary axonemes) for the diagnosis of primary ciliary dyskinesia."

Originally I was thinking 88348 with a 26 modifier but that can't be right becasue a lab has already billed in another facility without the TC modifier. Then I thought 80500: Lab Consult but apparently there would be a conflict with place of service. As we would use "office" place of service.

Is there an appropriate e/m code even though the patient is not present or seen?

Any thoughts??
