How Telehealth Billing Has Changed in Recent Years
Telehealth went from a niche reimbursement category to a daily billing reality almost overnight. The rules that governed it, however, did not change at the same speed. What started as emergency flexibilities during the public health emergency has slowly shifted into a permanent but uneven set of payer policies that vary by state, by payer, and sometimes by the specific patient population being served.
Practices that built telehealth into their care model during the emergency period now face a billing landscape with two layers stacked on top of each other. The temporary flexibilities are slowly phasing out. The permanent rules are still being written. Somewhere in between, claims are being submitted, and a measurable percentage of them are coming back denied.
Telehealth billing today fits inside the wider scope of medical billing in healthcare, but it carries its own rulebook. Practices delivering virtual services need a billing operation that knows the difference.
The Codes and Modifiers That Run Telehealth Billing
Most telehealth claims succeed or fail on three small details: the CPT or HCPCS code, the modifier, and the place of service code. Each one carries its own logic. Accurate medical coding services make the difference between a paid claim and a denied one.
- Modifier 95 indicates a synchronous audio and video telehealth service. Used on most therapy, evaluation, and management visits delivered remotely.
- Modifier 93 indicates an audio-only service. Recognized by Medicare for a defined list of services and increasingly accepted by commercial payers.
- Modifier GT was historically used for telehealth on institutional claims and still appears on some payer policies, even though most have moved to modifier 95.
- Modifier GQ covers asynchronous store-and-forward services in approved demonstration programs.
- Modifier G0 indicates a telehealth service for the diagnosis and treatment of acute stroke.
On the place of service side, two codes do the heavy lifting. POS 10 is used when the patient is at home. POS 02 is used when the patient is at any other location. The choice between them affects payment rates because some payers reimburse home telehealth at the full non-facility rate while applying facility rates to POS 02.
Place of Service: The Detail That Quietly Changes Reimbursement
Place of service is the most overlooked field on a telehealth claim. Many practices set a default POS code in their EHR template and never revisit it. That default is often wrong for at least some of their visits.
The simple rule is this. Document where the patient was at the time of service, not where the provider was. A patient connecting from home gets POS 10. A patient connecting from a clinic, school, or workplace gets POS 02. This documentation has to come from the visit note, not assumed from a calendar entry or scheduling field.
Getting this wrong by even one step means submitting a claim that pays less than it should, or one that gets flagged in post-payment review. Over hundreds or thousands of telehealth visits, the gap between correct and default POS adds up to real money.
Where Telehealth Claims Get Denied
Telehealth denials cluster around a small set of repeatable issues. Most of them are preventable with cleaner front-end workflows.
- Submitting a claim without a telehealth modifier when the payer requires one
- Using modifier 95 on an audio-only visit (modifier 93 should be used instead)
- Wrong place of service code based on patient location
- Service not on the payer’s covered telehealth list for that plan year
- Patient consent for telehealth not documented in the visit note
- Patient seen across state lines without provider licensure in that state
- Technology platform not HIPAA-compliant or not noted in documentation
These denials add up because telehealth claim volume tends to be high. A small denial rate at scale is a large dollar figure at year-end. Pairing strong denial management services with proven strategies for reducing denials and cleaner upfront eligibility verification recovers most of that revenue and prevents the next round of denials from happening at all.
Documentation Requirements for Clean Telehealth Claims
The documentation that protects a telehealth claim is more specific than what protects an in-office visit. Six elements should appear in every telehealth note:
- Patient location at the time of service (city and state at minimum)
- Provider location at the time of service
- Type of technology used (audio-video, audio-only, secure messaging)
- Patient consent for telehealth, ideally documented at the start of the visit
- Total visit time, with start and stop times for time-based codes
- Medical decision making or clinical content that supports the level of service billed
These details should flow naturally from EHR templates rather than being typed manually each time. Clean EHR integration with structured telehealth fields makes documentation automatic and audit-ready.
The Operational Side of Telehealth Billing
Beyond codes and modifiers, telehealth billing has operational layers that practices often underestimate. Strong revenue cycle management workflows tie all of these layers together so claims move through the system without leaks.
Multi-state telehealth introduces credentialing services complexity. A provider seeing patients in three states needs to be licensed and credentialed with each payer in each state. Gaps in any of these chains block reimbursement.
Payer mix also matters. Medicare, Medicaid, and commercial payers all treat telehealth differently. Medicare maintains a defined telehealth services list that updates annually. Medicaid rules vary by state. Commercial payers each have their own coverage policies, modifier requirements, and prior authorization rules. A practice billing across all three needs a system that tracks payer-specific differences instead of treating telehealth as one uniform category.
Most small and mid-size practices struggle to keep up with these moving parts internally. The benefits of outsourcing medical billing tend to show up first on telehealth claims because the rule complexity per claim is higher than almost any other category. A specialized billing operation tracking modifier updates, POS rules, and payer policies daily gives practices a steadier reimbursement stream than internal teams stretched across other priorities.
The Bottom Line on Telehealth Billing
Telehealth is here to stay, but the billing rules behind it will keep shifting for years. Practices that win at telehealth treat the billing operation as its own discipline. Clean documentation, correct modifiers, accurate place of service codes, and tight payer-by-payer tracking turn telehealth from a complicated reimbursement category into a steady revenue line that scales as virtual care continues to grow.
