What does the red circle with a slash mean in HCPCS coding?

In HCPCS coding, a red circle with a slash indicates that a specific code is not covered or valid for use by Medicare. This symbol serves as a visual cue for coders and healthcare providers to understand that the service or item associated with this code may not be reimbursed or recognized by Medicare. This information is vital for ensuring that providers are aware of which services are eligible for payment under Medicare, helping to avoid claim denials and billing issues.

The presence of this symbol impacts the way coding is approached as it urges providers to seek alternative codes for services that may be covered or to advise patients of potential out-of-pocket costs for services linked to a non-covered code.
