When your office receives a request for medical records to substantiate the chiropractic services you rendered and billed to Medicare, our nurse reviewers review the documentation and verify that all the required documentation has been met. If you met the documentation requirements, the nurse reviewers will send the documentation to a chiropractic consultant to determine the medical necessity of the services. If you did not meet the documentation requirements, the nurse reviewers will deny the services based on the lack of documentation.
