The CPT® Code 99602 refers to the administration of home infusion or specialty drugs, specifically indicating the service provided per visit for a duration of up to two hours. This code is utilized when a healthcare professional administers a specialty drug, which may include intravenous medications, in a patient's home setting. The term "home infusion" signifies that the administration occurs outside of a traditional healthcare facility, allowing for more personalized care in a familiar environment for the patient. It is important to note that this code covers the initial two hours of service; for any additional time spent administering the drug beyond this period, the same code (99602) should be listed separately to account for each additional hour of service provided. This structured approach ensures accurate billing and reimbursement for the healthcare services rendered during home infusion therapy.

The CPT® Code 99602 is indicated for use in situations where a patient requires home infusion of a specialty drug. This may include patients with chronic conditions that necessitate ongoing medication administration, such as those receiving intravenous therapies for infections, autoimmune disorders, or other medical conditions that require specialized drug treatments. The procedure is performed to ensure that patients receive necessary medications in a comfortable and familiar environment, which can enhance adherence to treatment regimens and improve overall patient outcomes.
The procedure associated with CPT® Code 99602 involves several key steps to ensure the safe and effective administration of the specialty drug in a home setting. The healthcare provider begins by preparing the necessary equipment and medication, ensuring that all materials are sterile and ready for use. This preparation may include gathering intravenous supplies, such as catheters, infusion pumps, and the specialty drug itself.
Post-procedure care following the administration of a specialty drug under CPT® Code 99602 includes monitoring the patient for any adverse reactions or complications that may occur after the infusion. The healthcare provider should provide the patient with instructions on what to expect following the treatment, including potential side effects and when to seek further medical attention. Additionally, the provider may schedule follow-up visits to assess the patient's response to the therapy and make any necessary adjustments to the treatment plan. Documentation of the procedure, including the drug administered, dosage, and patient response, is essential for compliance and billing purposes.
