A radiopaque marker may include a body formed of a polymer and being adapted to be disposed around a portion of an implantable medical lead and a symbol formed of at least a radiologically dense powder or liquid added to the body and designed to identify the implantable medical lead as being safe application of a medical procedure. In some instances, the symbol may be formed of a polymer mixed with the radiologically dense powder or liquid. The body may also be formed of a polymer mixed with a radiologically dense powder or liquid wherein the mixed polymer forming the symbol is radiologically denser than the mixed polymer forming the body.
