n the CCI, which type of codes cannot both be billed for a patient on the same day of service?

Answer 1

There is a database, the NCCI (National Correct Coding Initiative). This database lists codes for services that are components of other services. For example, 47562 is a laparoscopic cholecystectomy, that procedure includes diagnostic laparoscopy 49320. The NCCI database is public and can be accessed at https://www.cms.gov/Medicare/Coding/NCCI-Coding-Edits at this link, you can access the database and instructions on reading it.
