Electron Microscopy of a Tissue Sample

Washington, DC rates for HCPCS 88348

This is a specialized examination of a tissue sample using an electron microscope, which reveals cell structures at a much finer level of detail than a standard light microscope can show. Pathologists use it for certain diagnoses — for example, some kidney diseases or unusual tumors — where the extra detail changes or confirms the diagnosis. It is reserved for cases where a routine microscopic exam does not give a clear enough answer.
