Why We Don't Remove S9443 Just Because an Aetna Patient Has Exhausted Their Benefit

The services you provide—not the patient's remaining benefits—should determine what appears on the claim.

One billing practice we've seen recommended is to remove HCPCS code S9443 from an Aetna claim once a patient has exhausted their covered lactation counseling benefit.

The reasoning is often that leaving S9443 on the claim may cause the remaining balance to be assigned to the patient.

While that may sound like a way to protect the patient, it raises an important compliance question:

If S9443 accurately described every previous visit, why would the exact same service suddenly disappear from the claim simply because the patient's benefit has been exhausted?

The Service Didn't Change

Imagine a patient receives six lactation visits.

For visits one through five, the provider performs the same comprehensive lactation counseling, documents the same type of encounter, and bills S9443.

On visit six, the provider performs the exact same service.

The only difference?

The patient has exhausted their S9443 benefit.

If nothing about the visit changed, why should the claim change?

Insurance Benefits Shouldn't Determine What Was Performed

A patient's insurance benefits determine:

• Whether the payer will reimburse a service

• How many visits are covered

• Whether patient responsibility applies

They do not change what happened during the encounter.

Medical coding is intended to describe the services that were actually performed—not simply the services that are still payable.

The Medical Record and the Claim Should Tell the Same Story

If the documentation clearly supports lactation counseling consistent with S9443 on every visit, but the final visit omits that code solely because the benefit has been exhausted, an auditor could reasonably ask:

"Why does the documentation describe the same service, but the claim no longer reports it?"

If the answer is:

"Because insurance wouldn't pay it."

that explanation is based on reimbursement—not on the clinical services that were actually delivered.

Coding Should Not Change Because Coverage Changes

One of the fundamental principles of compliant medical billing is that code selection should be based on:

• The service provided

• The documentation

• Applicable coding guidance

• Payer policy

It should not change simply because the patient's benefits have been used.

The same documented service should generally be coded the same way unless the nature of the service itself has changed or the payer has published instructions directing otherwise.

Protecting Patients Is Important—But So Is Accurate Claims Reporting

Every provider wants to minimize unexpected costs for patients.

However, the solution should not be to remove a code that accurately reflects the care provided if the only reason for removing it is that the benefit has been exhausted.

Instead, providers should understand:

• the payer's published benefit limitations,

• their contractual obligations,

• patient financial responsibility,

• and any available appeal or exception processes.

Our Philosophy

At SunShyn, we believe every claim should accurately reflect the care that was delivered.

If today's visit is clinically the same as the previous five visits, our starting point is that the coding should also be consistent.

Insurance benefits may determine whether a service is paid.

They should not determine whether that service appears on the claim.

The Bottom Line

Running out of benefits does not change the care you provided.

If S9443 accurately described the visit before the benefit was exhausted, the exhaustion of that benefit alone does not change the nature of the service that was performed.

Coding should tell the story of the patient's care—not simply the story of what the insurance company is still willing to reimburse.
