How To Use CPT Code 88356

CPT 88356 describes the morphometric analysis of a nerve performed by a qualified provider, typically a pathologist, to evaluate its size, shape, and other physical features. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 88356?

CPT 88356 can be used to describe the morphometric analysis of a nerve performed by a qualified provider, usually a pathologist. This analysis involves evaluating the size, shape, and other physical features of the nerve to gather important diagnostic information. The test is typically ordered to assess peripheral neuropathies, such as small fiber neuropathy, which is characterized by reduced nerve fiber density and pain in the extremities.

2. Official Description

The official description of CPT code 88356 is: ‘Morphometric analysis; nerve.’

3. Procedure

1. After a lab analyst prepares slides, the qualified provider, typically a pathologist, performs a morphometric analysis to evaluate the size, shape, and other physical features of a nerve.
2. The provider may use manual methods with microscopy or automated methods to assess the nerve.
3. The analysis involves examining the nerve for physical features such as nerve type (small fiber or large fiber), diameter, number, and density.
4. The provider may also compare the results to normal reference ranges to aid in the diagnosis of peripheral neuropathies.

4. Qualifying circumstances

CPT 88356 is typically performed when a clinician suspects a peripheral neuropathy, such as small fiber neuropathy, and wants to assess the physical features of a nerve. The test is ordered to evaluate the size, shape, and other characteristics of the nerve, which can provide valuable diagnostic information. The provider performing the analysis must be a qualified professional, usually a pathologist, who has the necessary expertise to interpret the results accurately.

5. When to use CPT code 88356

CPT code 88356 should be used when a qualified provider, typically a pathologist, performs a morphometric analysis of a nerve to evaluate its physical features. This code is appropriate when the analysis is ordered to assess peripheral neuropathies, such as small fiber neuropathy, and to aid in the diagnosis of related conditions. It is important to ensure that the analysis is performed by a qualified provider and that the test is medically necessary based on the patient’s clinical presentation and symptoms.

6. Documentation requirements

To support a claim for CPT code 88356, the provider must document the following information:

• Reason for ordering the test, including the suspected peripheral neuropathy
• Details of the morphometric analysis performed, including the physical features evaluated
• Comparison of the results to normal reference ranges, if applicable
• Interpretation of the results and their significance in the context of the patient’s clinical presentation
• Signature of the qualified provider performing the analysis

7. Billing guidelines

When billing for CPT code 88356, ensure that the analysis is performed by a qualified provider, typically a pathologist, who has the necessary expertise to interpret the results accurately. It is important to follow the specific documentation requirements and provide all necessary information to support the medical necessity of the test. Additionally, consider any applicable coding guidelines and modifiers that may be required for accurate billing.

8. Historical information

CPT code 88356 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates or changes to the code since its addition.

9. Examples

1. A pathologist performing a morphometric analysis of a nerve to evaluate the physical features in a patient with suspected small fiber neuropathy.
2. A qualified provider assessing the size, shape, and other characteristics of a nerve to aid in the diagnosis of a peripheral neuropathy.
3. A pathologist comparing the results of a morphometric analysis to normal reference ranges to determine if a patient has a nerve disorder.
4. A clinician ordering a morphometric analysis of a nerve to gather diagnostic information for a patient with unexplained pain in the extremities.
5. A qualified provider performing a morphometric analysis of a nerve to assess its physical features and aid in the diagnosis of a peripheral neuropathy.
6. A pathologist interpreting the results of a morphometric analysis to determine the presence of a nerve disorder in a patient with clinical symptoms suggestive of a peripheral neuropathy.
7. A clinician ordering a morphometric analysis of a nerve to evaluate its size, shape, and other physical features in a patient with suspected nerve damage.
8. A qualified provider performing a morphometric analysis of a nerve to assess its physical characteristics and provide valuable diagnostic information for a patient with peripheral neuropathy.
9. A pathologist comparing the results of a morphometric analysis to normal reference ranges to aid in the diagnosis of a patient with suspected small fiber neuropathy.
10. A clinician ordering a morphometric analysis of a nerve to gather important diagnostic information for a patient with unexplained sensory symptoms.
