Hi - Is it possible the problem is the code? The COVID-19 FAQs at
https://www.cms.gov/files/document/03092020-covid-19-faqs-508.pdf say:
Question: Who can bill for the Medicare specimen collection fee?
Answer: Independent laboratories can bill Medicare through their MAC for the specimen collection fee. The specimen collection fee applies if the specimen is collected by trained laboratory personnel from a homebound or non-hospital inpatient and the specimen is a type that would not require only the services of a messenger pick up service. However, the specimen collection fee is not available for tests where a patient collects his or her own specimen.
If you are billing for an independent lab, perhaps the path/lab forum community has some insights.
