Modified Barium Swallow CPT Code: 74230 vs. 92611 Billing Guide

Difficulty in swallowing of liquid is present, and the physician suggests that a modified barium swallow test be performed. Just one mistake in coding is enough to completely invalidate a claim. Right Codes for CPT Modified Barium Swallow should be chosen based on the distinction made between the radiologic imaging service and the evaluation of the speech-language pathologist.

Code 74230 is for the radiologic imaging service for the modified barium swallow, and code 92611 is for the fluoroscopic swallowing function assessment by the speech-language pathologist. The two codes may be used together in one day if the services were provided and documented.

Here is the guide to code selection documentation, modifiers, Medicare, and avoidable coding mistakes.

What Is a Modified Barium Swallow Study?

MBSS stands for Modified Barium Swallow Study and refers to an x-ray test that is conducted to examine the process through which a person consumes substances from the mouth and throat.

In MBSS, patients consume food and liquids containing the barium contrast substance, after which it becomes the role of the clinical team to evaluate the manner in which the bolus moves and the swallowing process, airway protection, and any form of penetration and aspiration.

It is the test that is ordered by physicians in the case of swallowing difficulties resulting from stroke, neurological diseases, treatment of the head and neck region, or other medical problems.

Which CPT Codes Apply to a Modified Barium Swallow?

Two codes form the foundation of modified barium swallow billing.

CPT code	Service	Typical reporting role
74230	Radiological examination of swallowing function using video or cine imaging	Radiologist/radiology service
92611	Fluoroscopic evaluation of swallowing function using video or cine recording	Speech-language pathologist
92610	Clinical evaluation of oral and pharyngeal swallowing function	Speech-language pathologist

The difference is important as CPT 74230 and 92611 are two separate tasks of two different professional specialists. CPT 92610 covers the clinical swallow study and not the instrumented one.

CPT 74230: Radiological Swallowing Examination

CPT 74230 is the code used by radiologists to describe the radiology component of the modified barium swallow test.

The radiology service encompasses the relevant radiological effort for the analysis of the swallowing process. In cases where billing teams bill separately for the professional and technical aspects of the service, they have to follow the payer’s guidelines on how to do it.

For instance, if a radiologist offers the service of interpretation alone, he/she can bill the payer using CPT 74230, with modifier 26.

Nonetheless, billing teams need not automatically attach modifier 26 to every code of CPT 74230.

CPT 92611: Speech-Language Pathology Evaluation

CPT 92611 is the description of the SLP’s fluoroscopic swallowing study. 

This examination includes the assessment of the patient’s ability to control the bolus, coordination of the swallowing process, airway protection, and reactions to the compensatory maneuvers.

The clinician makes conclusions based on the results of the examination and records physiological data.

It is essential to note that CPT 92611 is the description of the functional examination of the SLP, not the radiologist’s job.

Modified Barium Swallow vs. Standard Barium Swallow: Why Coding Differs

Despite their similar names, “barium swallow” and “modified barium swallow” examinations do not always refer to the same test.

The basic barium swallow examination normally centers around the esophagus and might be helpful for doctors in investigating any problems with the esophagus.

The modified barium swallow examination is more concerned with the oral and pharyngeal aspects of swallowing.

Comparison	Modified barium swallow	Standard barium swallow
Primary focus	Oral and pharyngeal swallowing	Esophageal anatomy and function
Common clinical concern	Oropharyngeal dysphagia or aspiration risk	Esophageal swallowing symptoms
Imaging approach	Dynamic swallowing-function assessment	Esophageal contrast examination
Common CPT reference	74230 and potentially 92611	74220 or another appropriate esophageal imaging code

These discrepancies have an impact on claim accuracy. The scheduler’s appointment name alone will not be enough to determine the appropriate CPT code.

Rather, the coder must look at the physician’s order, the exam, the imaging, and the professional evaluations.

Can Providers Bill CPT 74230 and 92611 Together?

Yes. There is a possibility of a radiologist and an SLP reporting their unique services at a single modified barium swallow session in cases where documentation and claim edit requirements for each service allow this.

But the billing team needs to be aware of the NCCI edits and modifiers required.

CMS placed a certain edit on this code set in 2020 but then removed the edit and allowed the separation reporting of codes along with an appropriate distinct service modifier.

When Does Modifier 59 Apply?

A situation satisfying the relevant coding guidelines is coded using Modifier 59.

In the case of the Medicare NCCI edit for codes 92611 and 74230 historically, CMS advised that the claim would be able to code 92611 first and Modifier 59 to 74230.

The billing department needs to check what edits apply in the current quarter before proceeding.

Modifying 59 should not be done simply on the fact that there were two different people who conducted the study.

What About Modifier 26 and TC?

Modifier 26 refers to the professional portion of the eligible diagnostic service. Modifier TC refers to the technical portion when separate component billing is required.

In case of code CPT 74230, the billing could include:

• Professional interpretation by the radiologist.
• The technical imaging facilities available at the facility.
• Global billing if the billing agency bills for the entire service.

Various billing methods and contracts from payers may influence the billing process. The billing staff must, therefore, ensure if the billing is of professional, outpatient hospital, or other type.

ICD-10-CM Diagnosis Coding for Modified Barium Swallow Studies

The procedure code describes the service performed by the provider. The ICD-10-CM code describes the medical indication for the test, as documented.

A modified barium swallow study can be ordered by a healthcare provider if the patient is experiencing dysphagia.

Common diagnosis codes include:

ICD-10-CM	Diagnosis
R13.12	Dysphagia, oropharyngeal phase
R13.11	Dysphagia, oral phase
R13.13	Dysphagia, pharyngeal phase
R13.10	Dysphagia, unspecified
R13.19	Other dysphagia

Example coding: A doctor diagnoses oropharyngeal dysphagia and recommends the patient undergo a modified barium swallow test to assess safe swallowing. In this case, the coder can possibly use R13.12, where appropriate per the medical record.

On the other hand, in cases where the physician indicates no more than nonspecific dysphagia, the coder cannot assume a more specific phase of swallowing.

For FY 2027, apply the proper ICD-10-CM code set along with the official coding guidelines. Physicians must also verify if the applicable Medicare contractor or private insurer has any medical necessity requirement.

Documentation Requirements for Accurate Modified Barium Swallow Billing

CPT code that is correctly coded does not make up for the lack of a comprehensive clinical record.

An excellent modified barium swallow study links all of the above elements together.

1. Establish the Clinical Reason for Testing

The ordering clinician should document the swallowing concern and explain why the examination would help evaluate the patient’s condition.

Relevant clinical history may include choking episodes, coughing with oral intake, suspected aspiration, or changes in swallowing after a neurological event.

2. Document the Details of the Examination

The imaging documentation must mention the details of the examination and related observations.

In cases where applicable, the testing of consistencies, anatomic findings, problems with swallowing and airway events can be mentioned.

3. Separate the Reports of Professionals

Each professional must document his/her findings separately.

For instance, the radiologist documents the results of the imaging study, while the SLP documents the swallowing function and the proper compensatory strategies.

4. Validation of the Clinical Report

Both professionals must provide a valid clinical report based on organizational and payer policies.

Additionally, the billing department should ensure that the rendering provider, the date of service and the correlation between procedure codes and the report are verified.

Common Modified Barium Swallow Billing Errors

Most avoidable claim problems begin before submission. A billing manager may encounter several predictable issues.

Billing error	Practical correction
Reporting 74230 for a different esophageal examination	Compare the order and actual imaging report
Reporting 92611 without supporting SLP work	Confirm the SLP performed and documented the evaluation
Incorrectly combining services	Review current NCCI edits and payer instructions
Automatically applying modifier 59	Verify the distinct-service requirements
Selecting a diagnosis without clinical support	Match ICD-10-CM coding to documented findings
Missing the professional imaging component	Review modifier 26 and the applicable billing arrangement

A claim is considered invalid in a situation whereby there is a failure to take into account the authorization needs, payer-specific medical necessity standards, or provider enrollment information.

Conducting an intensive examination prior to submission would help detect such cases.

How to Prevent Modified Barium Swallow Claim Denials

To avoid denials, a pre-submission review can help the practice find out mistakes in coding, avoid denials, and payment delays.

Modified Barium Swallow Billing Checklist

– Ensure that there are physician orders and medical necessity.

– Verify whether it’s CPT 74230 or 92611 depending on the provided services.

– Verify documentation by the radiologist and SLP.

– Ensure proper ICD-10-CM diagnoses.

– Review NCCI edits and modifiers.

– Ensure that billing is done for both professional and technical services.

– Verify the coverage and requirements from the payers.

– Review the provider information and authenticated reports.

Review Repeated Studies Carefully

Frequent tests could prompt queries on the necessity of the tests because the documents do not provide a justification for the need for more tests.

The treating doctor needs to establish the clinical change or whatever else is necessary for performing another test.

For instance, a patient who suffers from difficulties swallowing after a neurological condition will require further testing. But the billing department must know the criteria of the payer.

Monitor Denials by Root Cause

Instead of dealing with denials separately, revenue cycle teams should start classifying repetitive issues.

The medical necessity denials, coding errors, modifier errors, and documentation errors have to be classified separately. This is necessary in order to determine any problems within the workflow of the practice.

Frequently Asked Questions

1. What is the CPT code for the modified barium swallow study?

The code for radiologic swallowing is 74230 and the code for speech language pathologist’s fluoroscopic swallowing is 92611. These codes vary depending on what was performed.

2. Is CPT 92611 the same code as CPT 74230?

No. CPT 92611 includes the SLP’s swallowing function assessment. CPT 74230 includes the radiological study. Both can be included in one session under proper coding criteria.

3. What is the difference between CPT 92610 and CPT 92611?

CPT 92610 includes a clinical swallowing study, while CPT 92611 involves an instrumental fluoroscopic swallowing study using video/cine recording.

4. Is a modified barium swallow study covered by Medicare?

Swallowing studies which are considered medically necessary can be covered under the appropriate Medicare coverage guidelines, documentation requirements and claims process guidelines.

5. Should a modifier be used for CPT 92611?

Not necessarily. It is determined based on the billing agreement and the appropriate claim edits that apply. In the case of billing both CPT 92611 and 74230, the NCCI instructions should be checked.

6. Can multiple modified barium swallow studies be billed on one day?

The providers need to be aware of the actual procedure performed and utilization guidelines of the payer. For instance, according to a Medicare MAC swallowing study billing article, there are restrictions for repetitive use of certain radiological swallowing codes on the same day.

7. What are the diagnosis codes for modified barium swallow billing?

R13 codes which belong to the dysphagia family are commonly used to describe swallowing disorders. Providers should select an appropriate diagnosis code.

Conclusion

One major distinction when billing for a modified barium swallow is that CPT 74230 codes for the radiological test, while CPT 92611 codes for the speech-language pathology assessment.

With all medical personnel  including providers , speech-language pathologists, radiologists, and billers having uniform documentation, then offices can catch coding errors earlier and prevent problems with claims that should not happen. Verification of claims allows revenue cycle specialists to address denials without leaving any outstanding balances.
