What 88309 covers

A pathologist examines a major resection specimen grossly and microscopically, assessing the removed tissue and relevant margins or associated structures. This level is used for specimen types classified as Level VI, including radical hysterectomy, radical prostatectomy, and radical mastectomy specimens. Hospital and independent pathology laboratories commonly perform the work on tissue removed during surgery.

Select the level by the specimen type and procedure, not simply because the diagnosis is cancer or the examination is complex. The surgical pathology report and requisition should identify the procedure and specimen, with findings supporting the examination performed. Medicare recognizes separate professional and technical components: modifier 26 reports the pathologist’s interpretation, modifier TC reports the technical work, and reporting without either modifier represents 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.

88309 billing questions

How does 88309 differ from 88307?

Use 88309 for specimen types designated Level VI, such as radical hysterectomy or radical prostatectomy specimens. Use 88307 when the specimen type is designated Level V; the diagnosis or perceived complexity alone does not determine the level.

Does a cancer diagnosis by itself support 88309?

No. Choose the code from the specimen type and operation performed. A malignancy diagnosis does not automatically make an examination Level VI.

When should modifier 26 or TC be reported?

Use modifier 26 for the professional interpretation and modifier TC for the technical service. Without either modifier, the claim represents the global service.

What documentation supports this level?

The requisition and pathology report should identify the specimen and the operation performed, such as a radical hysterectomy. The report should document the gross and microscopic examination.

Can special stains be reported with 88309?

A special-stain service is distinct from the Level VI tissue examination and may be reported separately when the applicable code requirements are met. The tissue examination code alone does not establish that a stain service was performed.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
