96360 CPT code is used to report the initial intravenous (IV) hydration infusion administered over 31 minutes to 1 hour. In 2025, precise coding, correct timing, and proper documentation are essential to meet payer rules and avoid denials. This guide explores updated guidelines, reimbursement tips, and documentation strategies for billing CPT 96360 effectively.
What Is CPT Code 96360?
CPT code 96360 is defined as “Intravenous infusion, hydration; initial, 31 minutes to 1 hour.” It is used when administering fluids (e.g., normal saline) to treat dehydration or support volume replacement. The companion add-on code +96361 is reported for each additional hour beyond the first.
2025 Coding and Documentation Updates
The 31-Minute Rule
Only report CPT 96360 if the infusion lasts at least 31 continuous minutes. Anything under 30 minutes is considered incidental and not separately billable. Always document start and stop times to validate service duration.
Primary vs. Secondary Infusions
Only one initial code (such as 96360) may be reported per date of service unless there are separate IV sites. Hydration is the lowest priority initial code. If another drug infusion is performed (e.g., 96365 for antibiotics), report hydration with +96361 if done sequentially—not concurrently.
Medical Necessity and Diagnosis
Coding must align with medical necessity. Common diagnoses include dehydration (E86.0), vomiting (R11.10), or fluid depletion. Document clinical need with supporting signs such as hypotension, poor intake, or lab findings. Lack of an appropriate diagnosis will likely result in a denial.
Billing Guidelines and Best Practices
- Facility vs. Professional Billing: In outpatient hospitals, hydration is billed by the facility—not the physician. In an office, the provider may bill if direct supervision is documented.
- Do Not Bill Concurrently: Avoid reporting hydration if it overlaps with a drug infusion. Payers consider concurrent hydration incidental.
- Hydration Volume: Volumes under 500 mL may be scrutinized. Ensure documentation justifies small volumes as medically necessary.
- Include HCPCS Codes: Report the fluid separately (e.g., J7030 for saline 1000 mL). Include the NDC number when required.
Common Denials and How to Avoid Them
- Missing or vague infusion time documentation
- Improper use of initial vs. add-on codes
- Lack of supporting diagnosis (e.g., no dehydration ICD-10 code)
- Billed by physicians in facility settings
- Routine use without clear medical necessity
FAQ
How long must an infusion last to bill 96360?
At least 31 continuous minutes. Anything under that is not separately reportable.
Can I bill 96360 with drug infusions?
Yes, but only if hydration is separate (not concurrent) and medically necessary. Use +96361 for hydration given after the drug infusion.
What if the hydration runs for 1 hour 45 minutes?
Report 96360 for the first hour and +96361 for the additional hour (since it exceeds 90 minutes).
