Modifier 90- Alternative Laboratory Platform Testing

Modifier 92 is used when a laboratory test is performed using a kit or transportable instrument designed for alternative testing platforms.

What is Modifier 92?

Modifier 92 identifies laboratory testing performed with a kit or transportable instrument that uses a single-use disposable analytical chamber. The testing platform generally does not require permanent dedicated space and is designed for simplified or portable use.

When to Use Modifier 92

• An eligible laboratory test uses an alternative testing platform.

• A kit or transportable testing instrument is used.

• The platform includes a disposable analytical chamber.

• The reported test and payer policy allow Modifier 92.

Billing Example

A provider performs an eligible infectious disease test using a portable testing kit with a disposable analytical chamber. Modifier 92 may be appended when the test and payer requirements support alternative laboratory platform reporting.

Documentation Tips

• Document the laboratory test performed.

• Identify the testing kit or instrument used.

• Record the test results in the medical record.

• Verify that the procedure and payer allow Modifier 92.

Common Denial Reasons

• The laboratory test is not eligible for Modifier 92.

• Documentation does not identify the testing platform.

• The modifier is used with a standard laboratory instrument.

• Payer-specific reporting requirements were not followed.
