Reimbursement policies, formerly known as coding and compensation policies, describe payment rules and methodologies for Current Procedural Terminology (CPT®) codes, Healthcare Common Procedure Coding System and ICD-10-CM coding for claims submitted as covered services. This information is a resource for our payment policies. It’s not intended to address all reimbursement-related issues. We regularly add and modify coding and compensation policy positions as part of our ongoing policy review process.
The following policies were updated:
