What 88323 covers

A pathologist uses 88323 when another facility or clinician sends tissue material for an outside diagnostic opinion and slide preparation is needed before review. The pathologist may prepare sections from a referred tissue block, examine the resulting slides, and issue a consultation report. This service can support a second opinion on a biopsy or resection when specialist review may affect diagnosis or treatment planning. It is commonly performed in a hospital or independent pathology laboratory.

Report 88323 for consultation on referred material when slide preparation is required. Use 88321 when the referred slides are already prepared; 88325 describes a comprehensive consultation that includes record review. Documentation should identify the material received, preparation performed, interpretation, and consultation report. CMS recognizes a professional component for interpretation and a technical component for equipment and staff. Report modifier 26 for the professional component, TC for the technical component, or neither modifier for the global service.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

88323 billing questions

When should I choose 88323 instead of 88321?

Use 88323 when referred material needs slide preparation for the consultation. Use 88321 when the pathologist reviews slides that were already prepared elsewhere.

How does 88323 differ from 88325?

88323 applies when slide preparation is required for the referred material. 88325 is for a comprehensive consultation that includes review of records.

Can the professional and technical components be billed separately?

Yes. Use modifier 26 for the professional interpretation and report, or TC for the technical work involving equipment and staff. Report the global service without either modifier when both components are furnished.

What documentation supports reporting 88323?

Document the referred material received, the slide preparation performed, the pathologist’s interpretation, and the consultation report.

Is 88323 the same as a routine surgical pathology examination?

No. 88323 is for a consultation on referred material requiring slide preparation. A routine surgical pathology examination, such as 88305, concerns examination of a specimen rather than this referred-material consultation.
