What 88362 covers

A nerve teasing preparation separates peripheral nerve biopsy tissue into individual fibers so the pathologist can examine their structure microscopically. A surgical pathologist or neuropathologist typically performs or interprets this specialized work in a hospital pathology laboratory or reference laboratory. It is used when evaluation of individual nerve fibers is needed in a neuropathy workup, rather than for routine examination of tissue sections alone.

Report 88362 when the teasing preparation is performed. Documentation should identify the nerve specimen and support the specialized preparation and diagnostic evaluation. CMS recognizes a global service when billed without a modifier. Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical work, including equipment and staff. The professional and technical portions have separate pricing under CMS.

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.

88362 billing questions

How does 88362 differ from 88356?

88362 reports nerve teasing preparation. 88356 is for morphometric analysis of nerve, a quantitative analysis rather than the teased-fiber preparation alone.

Can 88362 be reported with routine examination of a nerve biopsy?

The teasing preparation is distinct from routine histologic examination of the biopsy. Document the separate work performed; 88305 is the related code for routine surgical pathology examination.

When should modifier 26 or TC be used?

Use modifier 26 for the professional interpretation and modifier TC for the technical work, including equipment and staff. Bill without a modifier when the same billing entity reports the global service.

What documentation supports 88362?

Identify the peripheral nerve specimen and document that it underwent teasing preparation for microscopic evaluation. The record should support the pathologist’s interpretation of the preparation.

Is 88362 the same as electron microscopy of nerve tissue?

No. 88362 covers teasing nerve fibers for microscopic evaluation; 88348 is for diagnostic electron microscopy.

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.
