What is 99601 CPT code?

CPT code 99601 is used when a nurse provides home infusion or specialty drug administration during a home visit. It includes nursing services for up to 2 hours per visit. This type of care is often used for patients who need IV antibiotics, hydration therapy, chemotherapy, or other medications but don’t need to stay in a hospital.

The service must meet medical necessity and be ordered by a healthcare provider. If more time is needed, an additional code (99602) is used for each extra hour. A modifier code may be added if the nurse makes more than one visit on the same day. This code ensures proper billing and supports safe, convenient treatment at home.
