Dietitian CPT Codes – Nutritional Counseling & Beyond

What is a CPT Code?

Current Procedural Terminology (CPT) codes are procedure codes that describe medical services provided by healthcare professionals. These five digit codes are used for reimbursement and reporting purposes. These codes are required when filing a claim with health insurance companies.

While there are over 10,000 CPT codes, dietitians generally use less than a dozen, with many dietitians never using more than two or three.

Why are CPT Codes Used?

The use of CPT codes provides a uniform shorthand, so that everyone from healthcare providers to insurance companies, can easily speak the same language. This keeps everything streamlined while improving accuracy and efficiency. Just like an ICD-10 code is used to describe the diagnose treated, a CPT code is used to describe the medical service provided.

Where does the CPT Code Go?

If billing on a CMS1500 form, the CPT code goes in box 24D. If you are providing a superbill to a patient, the CPT code should be included.

Nutrition Counseling CPT Codes

The Medical Nutrition Therapy, or MNT, codes are the go-to codes for registered dietitians when providing nutrition counseling. They include CPT codes 97802, 97803 and 97804.

MNT CPT Codes Chart including 97802, 97803 and 97804

CPT Code 97802

The description of CPT code 97802 is, “medical nutrition therapy; initial assessment and intervention, individual, face-to-face with the patient, each 15 minutes.” 

This code is a time based code and is billed for each 15-minute increment. So, if an initial appointment is 60 minutes long, it will be billed for 4 units. Rounding is allowed with this code and is done using the 8-minute rule.

CPT Code 97803

The description of CPT code 97803 is, “medical nutrition therapy; re-assessment and intervention, individual, face-to-face with the patient, each 15 minutes.” This code is to be used when follow up MNT appointments are performed. 

In other regards, this code is quite similar to 97802. It generally pays out less than 97802.

CPT Code 97804

CPT Code 97804 is the third MNT code and is described as, “medical nutrition therapy; group (2 or more individual(s)), each 30 minutes.” This code is to be used when performing group MNT sessions. 

This is a time based code, but is based on 30-minute units, rather than 15-minute units.

Other Codes Dietitians May Use

Dietitians may use other codes beyond the MNT codes, but it is advised to proceed with caution. Make sure you understand what the code means, how it can be billed, and if it is part of your contract. 

It can be tempting to bill for a service that pays out well, but it is important that providers bill correctly and with integrity. Speaking with your compliance and billing team, the payer, the Academy of Nutrition and Dietetics (AND) and/or a healthcare attorney is recommended if you are venturing beyond the MNT codes.

HCPCS Code G0270

G0270 is actually not a CPT code, but rather a Healthcare Common Procedure Coding System (HCPCS) code. Although CPT and HCPCS are technically different, they function the same and are put in the same place on the CMS1500 form.

The description of G0270 is, “Medical Nutrition Therapy; reassessment and subsequent intervention(s) following second referral in the same year for change in diagnosis, medical condition, or treatment regimen (including additional hours needed for renal disease), individual, face-to-face with the patient, each 15 minutes.”

This code can be used to get additional follow up appointments beyond the general 3 hour and 2 hour limit that Medicare has. An additional referral is required.

HCPCS Code G0271

The description of G0271 is, “Medical Nutrition Therapy reassessment and subsequent intervention(s) following second referral in the same year for change in diagnosis, medical condition, or treatment regimen (including additional hours needed for renal disease), group (2 or more individuals), each 30 minutes.”

This code is similar to G0270 but is for group MNT, rather than individual.

HCPCS Code G0446

Code G0446 is used to bill Medicare for Intensive Behavior Therapy for cardiovascular disease and is defined as, “annual, face-to-face intensive behavioral therapy for cardiovascular disease, individual, 15 minutes.”

This benefit must be billed “incident to” a physician or other prescribing provider, so most dietitians in private practice are not rendering this service. However, if a dietitian has a relationship with a primary care office, billing for this service could be an option.

HCPCS Code G0447

The G0447 code is used to bill Medicare for Intensive Behavioral Therapy for obesity. It’s defined as, “individual; face-to-face behavioral counseling for obesity, 15 minutes.” 

This service must also be billed incident to a physician or other prescribing provider. 

HCPCS Code G0473

HCPCS Code G0473 is very similar to the G0447 code, but it is used for a group, rather than an individual. It is described as, “group; face-to-face behavioral counseling for obesity, 30 minutes.” Note that it is a 30-minute code, not a 15-minute code.

HCPCS Code S9470

HCPCS code S9470 is defined as, “nutritional counseling, dietitian visit,” and is the original nutrition counseling code as it existed before the MNT codes were introduced. Now that the MNT codes have been around, you may or may not see S9470 being covered by private payers. Medicare does not reimburse for this code.

HCPCS Code G0108

Code G0108 is defined as, “diabetes outpatient self-management training services, individual, per 30 minutes.” This benefit is intended to be used to educate patients on diabetes self-management; including topics such as blood sugar monitoring, diet, exercise and insulin regimens.

Only providers that are a part of accredited programs can bill Medicare for this service. Commercial and medicaid plans may not have this requirement, but it is important to clarify this before billing for the service.

G0108 is a time-based code with a unit of 30 minutes. CMS does not have specific guidance on rounding for this code, therefore, it is generally recommended not to round.

HCPCS Code G0109

HCPCS code G0109 is very similar to G0108, but it is used  for groups. It is defined as, “diabetes outpatient self-management training services, group session (two persons or more), per 30 minutes.”

CPT Code 95249

CPT code 95249 is described as, “ambulatory continuous glucose monitoring of interstitial fluid via a subcutaneous sensor for a minimum of 72 hours; patient-provided equipment, sensor placement, hook-up, calibration of monitor, patient training, and printout of recording.”

This code is used when training a patient on a continuous glucose monitor (CGM). A dietitian will need to bill incident to a physician when billing Medicare. Some plans may allow billing incident to an advanced practice provider as well, but a dietitian or other non-prescribing healthcare provider can never bill directly under their NPI for this code.

Per the American Medical Association’s CPT 2021 Professional edition, this code cannot be used more than once, unless the patient obtains a new and/or different model of data receiver. 

CPT Code 95250

The description of CPT code 95250 is, “ambulatory continuous glucose monitoring of interstitial fluid via a subcutaneous sensor for a minimum of 72 hours; physician other other qualified healthcare professional (office) provided equipment, senor placement, hook-up, calibration of monitor, patient training, removal of senor, and printout of recording.”

This code is similar to CPT code 95249, but is used when a professional CGM, rather than a personal CGM, is provided. The same rules regarding billing incident to apply. This code can be billed once a month. 

CPT Code 94690

CPT code 94690 is described as, “oxygen uptake, expired gas analysis; rest, indirect (separate procedure).” This is a pulmonary diagnostic testing and therapies code, but can potentially be  billed when using indirect calorimetry, such as a MedGem, to measure resting metabolic rate. The device must be FDA approved for this code to be billed.

Code G0438 is defined as, “annual well visit; includes a personalized prevention plan of services (PPPS), initial visit,” while code G0439 is, “annual well visit; includes a personalized prevention plan of services (PPPS), subsequent visit.”

Annual well visits are a Medicare benefit. They must be billed incident to the physician.

Frequently Asked Questions

How Do I Know What Codes I Can Bill For?

Your contract with the health insurance company should list all the procedure codes you can bill with. Since every plan may have different coverage, it is also important for either the provider or the patient to check benefits for the specific plan as well.

Should I Copy What Codes Other Dietitians are Billing with if They are Getting Paid?

It can be tempting to bill for different codes, especially if you hear from a colleague or members of a dietitian Facebook group, that they are making good money off of them. However, I highly recommend using caution when straying from the MNT codes.

Make sure you truly understand what the code means and what is required to fulfill the definition. Get information from sources such as CMS, AND and the payers directly. 

There is, unfortunately, a lot of misinformation spread between dietitians regarding coding and billing. Remember that dietitians are trained to be experts in food and nutrition, not in reimbursement. We need to do our due diligence to get information from credible sources to make sure we are doing things correctly. 

Even if you are personally getting paid for different codes, realize that insurance companies can claw back money that has been previously paid out. Every state has different laws on how far out insurance companies can do this. You can also reference your contract for further information.

Are All CPT Codes Time Based?

Not all CPT and HCPCS codes are time based codes. For example, 97802 and 97803 are time based, but S9470 is not. 

Most time based codes are based on a 15-minute increment, but some are based on other increments such as 30 minutes.

Final Thoughts

The MNT codes, CPT 97802, 97803 and 97804 are the most common procedure codes used to bill for nutrition counseling. However, there are many other procedure codes that fall within a dietitian’s scope of practice.
