The official description of Modifier 92 is “Alternative laboratory platform testing”.
Examples of procedures that require Modifier 92 include an antibody HIV 1 test, a rapid strep test, and a rapid flu test.
When using Modifier 92, it is important to document the use of the alternative laboratory platform test in the patient’s medical record. The documentation should include the reason for using the test, the type of test performed, and the results of the test.
To bill for Modifier 92, the CPT code for the laboratory test should be reported with Modifier 92 appended. Modifier 92 may affect the reimbursement rate for the test, so it is essential to check with the payer for specific billing guidelines.
7. Common mistakes
One common mistake that medical coders make when using Modifier 92 is failing to document the use of the alternative laboratory platform test in the patient’s medical record.
Another mistake is using Modifier 92 when it is inappropriate, such as when a traditional laboratory test is available. To avoid these mistakes, it is important to clearly understand the appropriate usage of Modifier 92 and document its use accurately.
8. Other modifiers related to Modifier 92
Other modifiers related to Modifier 92 include Modifier 91, which is used to indicate repeat clinical diagnostic laboratory test, and Modifier 90, which is used to indicate reference (outside) laboratory.
