CPT Codes for IV Fluid and Medication Infusions: A Comprehensive Guide

Accurate CPT coding for intravenous infusions is essential for proper reimbursement and compliance. Coding depends on the specific service provided, duration, and whether multiple infusions are administered sequentially or concurrently.

Common IV Infusion CPT Codes

CPT Code	Description
96360	IV hydration infusion, initial 31-60 minutes
96361	IV hydration infusion, each additional hour
96365	IV infusion therapy (non-chemotherapy), initial 30 minutes
96366	IV infusion therapy, each additional hour
96367	Additional sequential IV infusion (different drug), up to 1 hour
96368	Concurrent IV infusion (different drug), per day
96372	Therapeutic/prophylactic/diagnostic injection, subcutaneous or intramuscular
96374	IV push, single or initial substance/drug
96375	IV push, each additional sequential substance/drug
96376	IV push, each additional concurrent substance/drug

Key Coding Principles

• Initial vs. Sequential: Only one "initial" code per encounter; subsequent infusions use sequential/add-on codes
• Hydration vs. Therapy: Distinguish between hydration (96360-96361) and therapeutic infusions (96365-96368)
• Concurrent vs. Sequential: Concurrent (simultaneous) uses 96368; sequential (back-to-back) uses 96367
• Time Documentation: Start/stop times must be documented for time-based codes

Example Scenario

A patient receives a 45-minute antibiotic infusion (96365), followed by a 30-minute different antibiotic (96367), with concurrent hydration running throughout (96361 for additional hour beyond first). All three codes would be reported with appropriate documentation.

Important Notes

• Always verify with the current CPT codebook and payer-specific guidelines
• Document medical necessity, drug names, dosages, routes, and exact infusion times
• Chemotherapy infusions use separate codes (96401-96450)
• Facility vs. professional coding rules may differ
