One Visit, Two Services: Would Your Lactation Chart Survive an Insurance Audit?

One of the most common mistakes we see isn't choosing the wrong CPT code—it's assuming the documentation supports every code on the claim.

Insurance companies don't audit visits as a whole. They audit each individual CPT code and ask one simple question:

"Does the medical record support this service?"

If the answer is no for even one code, that portion of the claim may be denied, downcoded, or questioned during an audit.

For lactation providers, this becomes especially important when billing combinations such as:

• 99404 + S9443

• 99344 + S9443

Although these claims may look similar, the documentation requirements are very different.

Two Claims. Two Documentation Standards.

Let's look at an example.

Scenario A

A provider bills:

• 99404 – Preventive counseling

• S9443 – Lactation counseling

This visit focuses primarily on education.

Scenario B

A provider bills:

• 99344 – Home Evaluation & Management

• S9443 – Lactation counseling

Now the provider is billing for both:

• a medical Evaluation & Management service, and

• lactation counseling.

The documentation standard is significantly higher.

Example 1: Billing 99404 + S9443

Preventive counseling codes are intended to document education, counseling, and risk reduction.

The record should clearly document:

Time

99404 is a time-based code.

Document:

• total face-to-face counseling time

• total visit time (if applicable)

• start and stop times if your practice routinely records them

Remember—time alone does not support the service. The documentation should also demonstrate how that time was spent.

Preventive Focus

The record should show the purpose of the visit.

Examples include:

• preventing nipple trauma

• maintaining milk supply

• return-to-work planning

• pumping education

• prenatal breastfeeding preparation

• preventing mastitis

• feeding expectations

• milk storage guidance

Education Provided

Clearly document what was taught.

Examples:

• latch techniques

• positioning

• flange sizing

• paced bottle feeding

• pumping schedules

• feeding frequency

• hand expression

• supplementation plans

Patient Participation

Document the patient's response.

Examples:

• demonstrated improved latch

• performed return demonstration

• verbalized understanding

• teach-back completed successfully

Plan

Include:

• home recommendations

• follow-up plan

• educational materials provided

• referrals if needed

Example 2: Billing 99344 + S9443

This documentation is very different.

Although 99344 may now be selected based on either Medical Decision Making (MDM) or total physician/QHP time under the current E/M guidelines, it is still an Evaluation & Management service. Time determines the level of service—it does not eliminate the requirement that an E/M service actually took place.

In other words:

Spending 60 minutes teaching breastfeeding does not automatically justify billing 99344.

The documentation should demonstrate that the provider evaluated and managed a medical condition in addition to providing lactation counseling.

What Should the E/M Portion Include?

History

Document clinically relevant history such as:

• maternal symptoms

• infant symptoms

• feeding history

• birth history

• medication review

• prior treatment

• weight history

• progression of symptoms

Examination

Document findings appropriate to the patient's condition.

Examples:

Maternal

• breast assessment

• nipple trauma

• engorgement

• signs of mastitis

• milk production

• surgical history affecting lactation

Infant

• oral anatomy

• suck assessment

• tongue mobility

• feeding effectiveness

• hydration

• jaundice

• weight concerns

Assessment

Clearly identify your clinical assessment.

Examples:

• nipple trauma

• low milk supply

• oversupply

• plugged ducts

• ineffective milk transfer

• breastfeeding jaundice

• poor weight gain

• suspected oral restriction

Medical Decision Making

This is where many documentation deficiencies occur.

Document:

• interpretation of your clinical findings

• why a particular assessment was reached

• treatment options considered

• risks and benefits discussed

• referrals made

• coordination with other healthcare providers

• follow-up interval and clinical rationale

Even when selecting the code based on time, your note should still demonstrate that evaluation and management occurred.

What Supports S9443?

The counseling portion should also be documented.

Examples include:

• latch instruction

• positioning

• pumping education

• milk storage education

• feeding plans

• anticipatory guidance

• caregiver education

• return demonstrations

Many providers naturally include these elements—but remember that S9443 documents the counseling service, while 99344 documents the medical evaluation and management.

An Easy Audit Test

When reviewing your documentation, ask yourself two questions.

If S9443 were removed from the claim...

Would my note still fully support billing an Evaluation & Management service?

If the answer is no, your E/M documentation likely needs improvement.

If 99344 were removed from the claim...

Would my documentation still fully support lactation counseling?

If not, your S9443 documentation may be incomplete.

Chart Review Checklist

Billing 99404 + S9443?

Your documentation should include:

• ✔ Total counseling time

• ✔ Preventive purpose

• ✔ Lactation education provided

• ✔ Patient participation

• ✔ Follow-up plan

Billing 99344 + S9443?

Your documentation should include:

• ✔ Appropriate history

• ✔ Clinical examination

• ✔ Assessment

• ✔ Evaluation and management of the patient's condition

• ✔ Medical decision making or total qualified professional time supporting the selected E/M level

• ✔ Treatment plan

• ✔ Separate documentation supporting the lactation counseling provided

The Bottom Line

Adding an E/M code to a lactation visit doesn't simply increase reimbursement—it changes the documentation standard.

A chart supporting 99404 + S9443 should clearly demonstrate preventive counseling and lactation education.

A chart supporting 99344 + S9443 should demonstrate both a medically necessary Evaluation & Management service and lactation counseling. While 99344 may be selected using total time under the current E/M guidelines, that time must be spent performing E/M activities. Documentation should still show the provider evaluated the patient, developed an assessment, and managed the patient's condition—not simply that additional counseling occurred.
