Official Description

Subcutaneous infusion for therapy or prophylaxis (specify substance or drug); each additional hour (List separately in addition to code for primary procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 96370 refers to the process of administering a subcutaneous infusion for therapeutic or prophylactic purposes, specifically for each additional hour beyond the initial hour of infusion. This code is utilized in conjunction with the primary procedure code, which is CPT® Code 96369, that covers the first hour of subcutaneous infusion. The procedure involves the careful setup of an infusion pump and the establishment of one or more infusion sites on the patient's body. Aseptic technique is crucial throughout the process to prevent infection, and it includes the use of sterile syringes and needles to withdraw the prescribed medication. The infusion sites are typically located in areas such as the abdomen, upper buttocks, lateral thigh or hip, and upper arm, and are prepped with antiseptic solutions to ensure cleanliness. Each site is tested to confirm proper placement in the subcutaneous tissue, and once verified, the needles are secured in place. The infusion of the medication is then initiated. CPT® Code 96370 is specifically designated for billing each additional hour of this infusion process, highlighting its role in ongoing treatment or prevention beyond the initial hour of therapy.

1. Indications

The procedure associated with CPT® Code 96370 is indicated for patients requiring ongoing therapeutic or prophylactic treatment through subcutaneous infusion. This may include, but is not limited to, the following conditions:

  • Chronic Pain Management Patients experiencing chronic pain may require continuous medication delivery to manage their symptoms effectively.
  • Hydration Therapy Individuals needing fluid replacement or hydration due to various medical conditions may benefit from subcutaneous infusion.
  • Medication Administration Patients who require long-term administration of specific medications, such as antibiotics or biologics, may utilize this method for consistent drug delivery.

2. Procedure

The procedure for CPT® Code 96370 involves several critical steps to ensure the safe and effective administration of the subcutaneous infusion. Each step is essential for the successful delivery of the therapy.

  • Step 1: Preparation of the Infusion Site The healthcare provider begins by selecting appropriate infusion sites based on the total dosage of the prescribed medication. Common sites include the abdomen, upper buttocks, lateral thigh or hip, and upper arm. The selected areas are then cleaned with an antiseptic solution to minimize the risk of infection.
  • Step 2: Setup of the Infusion Pump A sterile syringe and needle are used to withdraw the prescribed amount of the medication. The pump reservoir is filled with the medication, and the pump and tubing are prepared for use. This setup is crucial for ensuring that the medication is delivered accurately and safely.
  • Step 3: Insertion of the Needle A needle is inserted into the subcutaneous tissue at each prepared site. The provider verifies proper placement by pulling back on the syringe to check for blood flow, ensuring that the needle is not in a blood vessel. Once confirmed, the needle is secured with tape to keep it in place during the infusion.
  • Step 4: Administration of the Medication After securing all infusion sites, the medication is administered through the pump. The infusion continues for the prescribed duration, and the healthcare provider monitors the patient for any adverse reactions or complications during the process.

3. Post-Procedure

After the completion of the subcutaneous infusion, the patient may be monitored for any immediate reactions to the medication. It is essential to assess the infusion sites for signs of infection, irritation, or other complications. Patients may receive instructions on how to care for the infusion sites and what symptoms to watch for that may require medical attention. If the infusion is to continue beyond the initial hour, CPT® Code 96370 should be used for each additional hour of therapy. Documentation of the procedure, including the medication administered, the duration of the infusion, and any observations made during the process, is critical for accurate billing and compliance.
