Why Billing CPT 96368 More Than Once Is Considered Double-Dipping

Reporting CPT 96368 more than once during the same encounter is double-dipping—and it’s a common audit finding.

Here’s why.

Concurrent Infusion Work Is Already Accounted For

CPT views concurrent infusions as secondary services that occur alongside the primary infusion. The additional work involved in managing a concurrent infusion is recognized once, not hourly and not repeatedly.

When coders attempt to:

• Bill 96368 for each hour of overlap

• Bill 96368 again when concurrency restarts

• Bill multiple units because multiple concurrent drugs were infused

they are billing the same work more than once.

That is the definition of double-dipping.

Example of Double-Dipping (Incorrect)

• Primary infusion runs for 4 hours

• Concurrent infusion runs for 2 hours

• Coder bills:

  • 96365

  • 96366 × 3

  • 96368 × 2

This is incorrect. CPT does not allow hourly billing for concurrent infusions.

Correct Coding to be Compliant with CPT 96368

• 96365 – Initial infusion

• 96366 – Additional hours of the primary infusion

• 96368 – Concurrent infusion (billed once only)

Even though the concurrent infusion ran for two hours, only the initial hour of concurrency is billable.

Why Payers Deny This

Payers deny or recoup these claims because:

• CPT 96368 is non–time-based

• There are no add-on hour codes for concurrency

• Reporting more than one unit inflates reimbursement without additional recognized work

In audit language:

“Billing exceeds CPT allowance for concurrent infusion services.”

Compliance Takeaway

Think of 96368 as a one-time indicator, not a duration-based service.

If concurrency occurs:

• Bill it once

• Do not count hours

• Do not repeat it later in the encounter

Anything more is double-dipping—and puts the claim at risk.
