CPT 96368 is one of the most frequently denied infusion codes in hospital and emergency department settings. Understanding when a concurrent infusion qualifies — and when it does not — is critical to preventing audits, payer takebacks, and downcoding.
In this guide, we’ll break down:
• What CPT 96368 actually means
• The difference between concurrent and sequential infusions
• Documentation requirements
• Real-world coding examples
• Common denial triggers
Real-World Charge Capture Insight
In ER charge capture, one of the most common errors I see is 96368 being reported simply because two medications were administered during the same encounter. However, unless documentation clearly shows overlapping infusion times through the same access site, the service does not qualify as concurrent.
When reviewing nursing documentation, I always confirm:
• Start and stop times overlap
• Same IV access site is documented
• Primary infusion is clearly identified
What Is CPT 96368?
CPT 96368 explained for reported a concurrent intravenous infusion.
A concurrent infusion occurs when:
Two infusions are running at the same time through the same IV line or the same IV access site.
This phrase drives correct coding:Same time. Same line.
CPT 96368 Code Description
96368 – Concurrent infusion (list separately in addition to code for primary procedure)
Important points:
It is an add-on code
It is never billed alone
It must be reported in addition to an initial infusion code
One Initial Infusion Rule (Critical)
Only ONE initial infusion code may be reported per encounter.
That initial infusion is:
96365 – Initial infusion, first hour
In all cases, remember:
Sequence codes by designating the initial service first.
Follow with all concurrent or subsequent pushes using the correct add-on codes.
Accurate sequencing ensures compliance and maximizes correct reimbursement no matter how many lines, pushes, or drips are on the workflow.
What Qualifies as a Concurrent Infusion?
A concurrent infusion must meet all of the following criteria:
Two IV infusions
Administered at the same time
Through the same IV line or same IV access site
The secondary infusion is not the primary service
Example of a True Concurrent Infusion
Antibiotic A infuses over 120 minutes
Antibiotic B starts and runs for 60 minutes at the same time
Both use the same IV access
Correct coding:
96365 – Initial infusion
96368 – Concurrent infusion
What Is NOT a Concurrent Infusion (Common Errors)
Sequential Infusions
If one infusion ends before the next begins, it is not concurrent.
Example:
Antibiotic A finishes
Antibiotic B starts afterward
This is sequential, not concurrent.Code 96367, not 96368.
Piggyback Misunderstanding
Piggybacked medications are often sequential, not concurrent.
If the primary infusion pauses or finishes while the piggyback runs:
The service is not concurrent
Even if the same IV line is used
Different IV Sites
If two infusions run at the same time through different IV sites, CPT 96368 is not appropriate.
CPT 96368 vs CPT 96367
Code | Meaning |
96367 | Sequential infusion of a new drug, given after the initial |
96368 | Concurrent infusion running at the same time |
Ask one key question:
Were both infusions running simultaneously?
If the answer is no, do not report CPT 96368.
Time Rules for CPT 96368
Unlike initial and sequential infusion codes:
CPT 96368 is not time-based well, sorta
You do not report hours or additional units
If the infusion qualifies as concurrent:
It is reported once per encounter, per CPT guidance
For example
Drug A Runs: 10:27 - 02:27 = 3 Hours 96365 96366x2
Drug B Runs: 11:15 - 01:15= 96368
Documentation Requirements (Why This Code Gets Denied)
To support CPT 96368, documentation must clearly show:
Overlapping infusion times
Same IV site or access
Identification of the primary versus secondary infusion
Nursing documentation that supports concurrency
If overlapping time is not clearly documented, payers may downcode, deny the add-on service, or recoup payment during audits.
Can Hydration Be Concurrent?
No.
Hydration is considered supportive therapy, not a concurrent or sequenital infusion when paired with therapeutic infusions.
If hydration is running with a medication infusion:
Hydration does not become concurrent
It follows hydration-specific CPT rules and hierarchy
Common CPT 96368 Explained Reasons For Coding Errors
Reporting 96368 for back-to-back infusions
Using 96368 simply because two drugs were ordered
Reporting multiple units of 96368
Confusing piggyback administration with concurrency
Missing overlapping start and stop times
Frequently Asked Questions About CPT 96368
Can CPT 96368 be billed more than once?
CPT 96368 is reported once per encounter.
Is CPT 96368 time-based?
No. Unlike initial and sequential infusion codes, 96368 is not time-based.
Can hydration be billed as concurrent?
No. Hydration follows separate hierarchy rules and is not considered concurrent when paired with therapeutic infusions.
Can I bill 96367 and 96368 together?
Yes, if documentation supports both a sequential infusion and a concurrent infusion during the same encounter.
