Telehealth Billing for Nutrition Therapy: Correct Modifier Usage Explained
Telehealth has grown into an important way of delivering care, especially for nutrition therapy. In fact, more than 12% of Medicare patients used telehealth billing services in late 2023. Studies also show that almost half of patients receiving nutrition therapy used audio-only visits. This makes billing more complex because payers need to know exactly how the service was provided.
One of the most important parts of nutrition therapy billing is the correct use of modifiers. Modifiers explain to payers whether the visit was done by video, phone, or another method. Using the wrong modifier often leads to claim denials or delays.
In this guide, we explain step by step how to apply modifiers correctly when billing for nutrition therapy sessions.
Step 1: Identify the Service (Video or Audio-Only)
Video sessions: Use modifier 95 for real-time, two-way video visits.
Audio-only sessions: Use modifier 93, but only if the payer allows it. Some older payers may still ask for modifier GQ for asynchronous encounters.
Step 2: Match Modifier with the Right CPT/HCPCS Code
Correct pairing of a CPT/HCPCS code with a modifier is key in medical billing services:
97802 – Initial assessment
Add modifier 95 for video-based visits, or modifier 93 if audio-only visits are allowed by the payer.
G0270/G0271 – For additional hours after referral
FQHCs/RHCs may require modifier FQ for audio-only sessions.
Some payers still accept GT or GQ in special cases.
Step 3: Correct Place of Service (POS)
POS 02 – Telehealth outside patient’s home
POS 10 – Telehealth from patient’s home
POS 11, 12, 22 – In-person visits
Institutional claims may also require Revenue Code 942 with CPT/HCPCS codes and the correct modifier.
Step 4: Special Rules for FQHCs and RHCs
Medicare requires G2025 for distant site telehealth visits.
Apply modifier 95 for video sessions or modifier FQ/93 for audio-only visits.
Always check with your Medicare Administrative Contractor (MAC) for local requirements.
Step 5: Document Everything
Good documentation supports your billing and prevents denials:
Record patient consent (verbal or written).
Note the modality (video or audio-only).
Explain the reason if only audio was used.
Include start and stop times for CPT 97802/97803.
Record provider and patient locations.
Keep detailed clinical notes.
Step 6: Avoid Common Mistakes
Don’t use modifier 95 for audio-only visits.
Always use modifier 93 when required for phone visits.
Make sure POS code matches the modifier.
Don’t assume payer rules are the same across all insurers.
Use older modifiers like GT/GQ only if specifically required.
Telehealth rules keep changing. Medicare has extended telehealth flexibilities, including audio-only visits, through March 2025. After that, audio-only will officially be considered part of telehealth when patients cannot use video. Commercial insurers and state Medicaid programs may update their rules even faster.
Because of this, many practices choose outsourcing telehealth billing and coding services to experts like 24/7 Medical Billing Services. Our team ensures the correct CPT/HCPCS code medical billing services are applied with the right modifiers, POS codes, and documentation. This reduces claim errors, prevents denials, and speeds up payments for nutrition therapy billing.
