Key Telehealth Billing Guidelines by Capline Healthcare Management Services

Telehealth is now normal for many patients, and it is not slowing down. But many practices still lose money because claims get denied for simple reasons: wrong place of service, missing modifiers, or unclear documentation. This is a real problem for dental groups because many patients delay care until pain gets worse. The CDC reports that 1 in 6 adults age 65 or older has untreated cavities, and 96% have had at least one cavity in their lifetime.

In this blog, we have explained telehealth billing, so your team can file cleaner claims, avoid denials, and improve telehealth billing & collection without frustrating patients.

What is telehealth billing

It is the process of turning a virtual service into a payable claim. That includes:

• Confirming the patient’s coverage and any telehealth limits
• Choosing the correct code set for the service (medical or dental)
• Adding the right place of service and modifiers when required
• Documenting the visit in a way that supports medical necessity
• Submitting, tracking, appealing when needed, and collecting patient responsibility

The main idea is simple. If the service is not clearly supported on the claim and in the note, the payer may delay, reduce, or deny payment.

Who can bill for telehealth services?

For Medicare, eligible providers include physicians, nurse practitioners, physician assistants, clinical psychologists, clinical social workers, certified nurse-midwives, and a few other qualifying types.

Federally Qualified Health Center (FQHCs) and Rural Health Clinics (RHCs) can bill as distant site providers for most telehealth services through December 31, 2027. For mental health and substance use services, that permission is permanent.

Medicaid is a different story in every state. And commercial payers each have their own rules. Always check before you bill.

Why telehealth billing gets tricky for dental and medical teams

Telehealth rules change by payer and sometimes by state. Even when a service is covered, a claim can still deny because the claim form does not match what happened in the visit.

Two common examples:

• The patient was at home, but the claim used the wrong place of service code.
• The visit was audio only, but the payer needed a specific modifier or stronger documentation.

Medicare policy updates also matter. Federal telehealth policy summaries confirm many Medicare telehealth flexibilities are extended through December 31, 2027, which affects how many clinics plan staffing and billing workflows.

How to code a telehealth visit, step by step

Coding in the right order prevents the most common errors. Here is the sequence that works.

Start with the service, not the modifier

Ask what actually happened. Was it a full clinical visit with assessment and treatment decisions? A quick check-in to decide if the patient needs to come in? A patient sending in a photo for review? Each one is a different service type with a different code. Picking the modifier first is where most billing mistakes begin.

Confirm how the visit happened

Live video, audio-only phone call, patient portal message, or store-and-forward (like a patient submitting recorded images), the technology used determines which codes and modifiers apply. A phone call and a video visit are not interchangeable from a billing standpoint.

Pick the right place of service code

This is simple in theory, but gets missed constantly. Use POS 10 when the patient was at home. Use POS 02 when they were somewhere else, like a clinic or pharmacy. Since January 2024, Medicare pays POS 10 claims at the non-facility rate, which is typically higher. Using the wrong code does not just cause a denial; it also affects how much you get paid.

Add a modifier only when it is actually required

Modifier 95 applies to certain synchronous telehealth services, mainly outpatient therapy in hospital settings. It is not a default modifier for every telehealth claim.

Modifier 93 is for real-time audio-only (phone-only) visits. The chart note must explain why the visit was audio-only.

Modifier FQ is used by FQHCs and RHCs for audio-only services. Some situations need both FQ and 93 together.
One of the most common billing errors is putting modifier 95 on every telehealth claim out of habit. That will get claims denied. Always check the payer rule first.

What to document so telehealth billing holds up

Your clinical note should look like a normal visit note, plus a few telehealth details.

Include:

• Chief complaint and relevant history
• Findings you could assess virtually
• Assessment and plan
• Prescriptions, referrals, follow up instructions
• Patient consent for telehealth
• Modality used (audio video or audio only)
• Patient location and provider location

If you provide audio-only services, you should also use a secure approach and follow privacy requirements. HHS guidance explains how HIPAA rules permit audio only telehealth when providers take reasonable safeguards.

Coding basics for cleaner telehealth billing

Use the correct place of service code

Place of service is one of the biggest denial triggers.

CMS describes:

• POS 10 as telehealth provided in the patient’s home
• POS 02 as telehealth provided other than in the patient’s home

Practical tip: make “patient at home yes or no” a required field in your scheduling template.

Use modifiers only when the payer requires them

Some payers want a telehealth modifier, some do not, and some accept it only for certain visit types. This is why payer specific rules matter.

A safe workflow is to keep a payer matrix that lists, for each payer:

• Allowed telehealth services
• Required POS
• Required modifiers
• Audio only rules

Teledentistry coding basics for dental claims

If the visit is billed to a dental plan, CDT teledentistry codes may apply.

The ADA guidance explains that:

• D9995 and D9996 are reported in addition to other dental procedure codes provided in the encounter, not by themselves
• These teledentistry codes apply to claims filed against a dental benefit plan

Simple way to remember it:

Teledentistry codes describe the “how” of the encounter, not the clinical work itself.

The most common reasons telehealth claims deny

Here are the denial patterns most practices see again and again:

The service is not telehealth eligible
The code billed is not allowed through telehealth for that payer, or the payer only allows it by video and it was done by phone.

Place of service does not match the patient location
POS errors are common and easy to prevent once intake captures home vs not home.

Modifier mismatch
A modifier is missing when required or added when not allowed for that payer’s telehealth setup.

Documentation is missing the telehealth proof
If the note does not show consent, modality, and locations, the claim may fail review even when care was appropriate.

How to improve telehealth billing & collection without upsetting patients

Collections work best when there are no surprises.

Use this simple approach:

• Tell the patient the expected cost before the visit whenever possible.
• Collect copay at the time of service (card on file, portal payment, or secure link).
• Send the statement quickly if there is a balance, using plain language.
• Follow up on denials early so the patient does not get billed months later.
• When billing is clean, patient collections usually improve naturally because the account is accurate and timely.

Conclusion

Good telehealth billing is not about adding complexity. It is about using the same simple checklist every time, documenting the basics, and matching payer rules for place of service, modifiers, and covered visit types.
If you keep those steps consistent, your telehealth billing guidelines become easy for staff to follow, and claims become easier for payers to process.

Telehealth billing errors are not usually about missing knowledge; they are about missing process.
