The Hidden Audit Risk of Billing Nutrition Therapy Codes for Lactation Visits

 Why getting paid doesn't always mean the claim was billed correctly.

As insurance coverage for lactation services continues to evolve, many IBCLCs are looking for ways to obtain reimbursement from commercial insurance plans. Unfortunately, some billing companies and online groups have begun recommending the use of Medical Nutrition Therapy (MNT) codes—particularly 97802 and 97803—for routine lactation consultations.

The reasoning is often simple:

"The claims pay."

However, payment alone does not determine whether a claim was coded correctly. In fact, using Medical Nutrition Therapy codes for lactation counseling may expose providers to significant audit and recoupment risk.

What Are Nutrition Therapy Codes?

CPT codes 97802 and 97803 were created for Medical Nutrition Therapy (MNT).

These codes describe services involving nutritional assessment, intervention, and ongoing management of medical conditions through nutrition therapy. Medicare limits payment for MNT to registered dietitians (RDs) and nutrition professionals who meet specific statutory requirements, and many commercial insurers adopt similar eligibility standards or establish their own credentialing requirements. Coverage and eligible provider types vary by payer. (law.cornell.edu)

An IBCLC credential is not the same as a Registered Dietitian credential, and an IBCLC should not assume they are eligible to bill MNT simply because breastfeeding involves infant nutrition.

Breastfeeding Is Not Automatically Medical Nutrition Therapy

Breastfeeding certainly involves nutrition, but a comprehensive lactation consultation is much broader than nutrition counseling.

A typical IBCLC visit may include:

• Latch and positioning assessment

• Milk transfer evaluation

• Pumping guidance

• Oral anatomy assessment

• Maternal breast assessment

• Nipple pain management

• Supplementation planning

• Return-to-work planning

• Milk supply concerns

• Feeding observations

• Individualized lactation care planning

These services are fundamentally different from Medical Nutrition Therapy as described by CPT.

Scope of Practice Matters

One of the most overlooked compliance issues is scope of practice.

Even if a payer processes and pays a nutrition code, providers should ask:

• Am I qualified under this payer's policy to report this code?

• Does the service I performed meet the CPT description?

• Does my documentation support Medical Nutrition Therapy rather than lactation counseling?

If the answer to any of these questions is "no," payment alone does not eliminate the compliance risk.

"It Paid" Is Not a Compliance Standard

One of the most common misconceptions in medical billing is:

"If insurance paid it, it must be correct."

Unfortunately, that is not how claim compliance works.

Claims are frequently paid through automated systems that cannot evaluate whether:

• the provider was eligible to report the code,

• the documentation supports the reported service,

• the CPT code accurately describes what occurred,

• or the payer intended to reimburse that provider type.

Many audits occur months or even years after payment.

The Real Financial Risk

If an insurer later determines that a nutrition therapy code was billed inappropriately, the consequences may include:

• Repayment of previously paid claims

• Medical record requests

• Expanded audits of additional claims

• Increased scrutiny of future billing

• Administrative burden responding to audit requests

These risks can significantly outweigh any short-term reimbursement gained from using a questionable coding strategy.

Every Payer Is Different

Some insurers may credential IBCLCs differently than others. Some state laws may expand the services certain provider types can bill. Some plans may have unique reimbursement policies.

That is why providers should never rely solely on statements such as:

• "Everyone bills it."

• "The Facebook group said it works."

• "Our billing company told us to use it."

Instead, providers should verify:

• their own credentialing status,

• the payer's published billing policies,

• the CPT code definition,

• and whether the documentation truly supports the service billed.

Choose Compliance Over Convenience

The goal of medical billing is not simply to obtain payment.

It is to submit claims that accurately reflect the services provided, are supported by documentation, and comply with payer requirements.

As lactation reimbursement continues to grow, IBCLCs deserve billing strategies that are both effective and defensible during an audit.

Using codes simply because they reimburse may create unnecessary risk for providers who trust that their claims are being billed correctly.

When in doubt, ask questions, request the supporting policy, and remember:

The best billing strategy is one you can confidently defend if your records are ever reviewed.
