Does anyone have any information on billing guidelines for the following 2018 HCPCS codes?

G9933-G9937 & G9912-G9913 & G9945. Are these codes solely for PQRS reporting? We were told my our Medicare carrier the following regarding G9933, G9937 & G9945 “Policy has informed us that these are going to be M status codes which are not covered by Medicare." Should we start to utilize these codes and report them to our Medicare carrier although they are M status codes?

Q9950: Will this code continue to be a pass-though code or fall under the ambulatory payment classification system, or be considered bundled?

Thank you
