The CS modifier is used to indicate that a service was provided as part of a federal or state government-funded program that is not Medicare. This modifier is typically used for Medicaid or CHIP (Children’s Health Insurance Program) services.
The 95 modifier is used to indicate that a service was provided via telehealth. This modifier was introduced during the COVID-19 pandemic to help providers bill for services delivered remotely.
When it comes to COVID-19 testing, the use of modifiers will depend on the specific circumstances. For example, if a COVID-19 test is performed in the context of a telehealth visit, the 95 modifier should be used to indicate that the service was provided remotely. Additionally, the CS modifier may be used if the test was performed as part of a state or federal government-funded program.
It’s important to note that the rules and guidelines around the use of modifiers can vary depending on the payer and the specific service being provided. Providers should consult with the payer and/or a qualified billing professional to ensure they are using the appropriate modifiers in their billing.
