Teledermatology isn’t just a pandemic afterthought anymore; it’s become woven into the fabric of modern dermatological practice. But the fact is, while clinical adoption has been swift, the business side remains surprisingly messy.
Teledermatology brings genuine value to patients and practices alike, but billing for it properly requires navigating a labyrinth of codes, payer policies, and evolving regulations.
Get it right, and you unlock a new revenue stream while improving patient access.
Get it wrong, and you’re looking at claim denials, revenue leakage, and administrative headaches that multiply faster than a dermatologist’s inbox.
Teledermatology Billing in Dermatology
Teledermatology enables dermatology practices to expand patient access, streamline follow-up care, and provide services beyond local regions. Most practices implemented teledermatology during the pandemic because they needed to keep seeing patients. The priority was clinical access, not billing infrastructure. Now that things have stabilized, the reimbursement strategy has moved to the top of the agenda.
Billing for virtual visits isn’t just a tweaked version of in-person billing. Some insurance companies will pay you the same as an in-person visit. Others cut the rate, add place-of-service rules, or limit what’s covered. Medicare keeps changing its rules, so what worked last year might not work this year.
The Rise of Teledermatology During COVID-19
Before COVID, only about 15% of dermatologists used telemedicine.
Medicare had strict rules: you needed an in-person visit first, you couldn’t treat patients across state lines, and licensing requirements limited interstate practice.
When the pandemic hit, CMS temporarily removed major restrictions. Direct patient visits were allowed, geographic restrictions were lifted, audio-only visits were covered, and state licensing was temporarily loosened.
Teledermatology adoption jumped to nearly 97% of dermatologists. Patients could see their doctors from home, and practices discovered they could manage follow-ups faster.
Several pandemic-era flexibilities, including home-based visits and audio-only teledermatology for non-behavioral care, have expired as of October 1, 2025. Geographic restrictions and approved originating site rules are back in effect.
Best Practices for Teledermatology Billing
Successfully billing for teledermatology comes down to fundamentals, executed consistently. Think of it as the difference between a practice that occasionally gets paid for virtual visits and one that reliably captures full reimbursement while staying compliant.
1. Verify Coverage Before the Visit
Confirm insurance coverage, including video versus audio-only eligibility, before each appointment. Checking coverage ahead of time helps prevent denied claims and ensures the visit can be billed correctly. Some payers require specific patient types, locations, or visit modalities for reimbursement, so verification is essential.
2. Maintain Thorough Documentation
Clear documentation is the foundation of defensible telehealth billing. Every encounter should demonstrate medical necessity, including why telehealth was chosen over in-person care. Include clinical findings, treatment decisions, and follow-up plans. Documenting the chosen modality, whether video or audio-only, supports reimbursement and protects the practice in case of audits.
3. Track Time Accurately
For time-based codes, record start and end times of all encounters, including non-face-to-face work such as reviewing patient photos, preparing notes, consulting colleagues, or communicating results. Accurate time tracking ensures appropriate coding, supports fair reimbursement, and avoids undercoding or overcoding.
4. Choose the Right Technology
Select a HIPAA-compliant telehealth platform that integrates with the electronic health record. Automatic syncing of documentation, CPT codes, place-of-service, and modifiers reduces errors. Manual workarounds increase the risk of mistakes, delays, and claim denials.
5. Define Clinical Boundaries
Determine which conditions can safely and effectively be managed through teledermatology. Routine cases such as psoriasis, acne, rosacea, atopic dermatitis, and medication monitoring are well-suited for virtual care. More complex evaluations, including total-body skin exams or suspicious lesions requiring biopsy, generally require in-person visits. Clearly documenting these boundaries supports patient safety and billing compliance.
6. Obtain and Document Patient Consent
Ensure patients provide documented consent for telehealth services before each session, including the method of delivery (video or audio-only). Recording consent in the EHR is required by many payers and state regulations.
7. Understand State-Specific Parity Laws
State parity laws determine whether telehealth visits must be reimbursed at the same rate as in-person visits. Understanding your state’s requirements ensures accurate payment expectations and compliance with regulations.
8. Apply Correct Codes and Modifiers
Use the appropriate CPT codes and any required modifiers for each teledermatology visit. Accurate coding, correct place-of-service assignment, and applying necessary modifiers, such as those for asynchronous care, ensure proper reimbursement and reduce claim denials.
9. Stay Up to Date on Payer Policies
Telehealth rules differ across Medicare, Medicare Advantage, and commercial insurers, and policies continue to evolve. Regularly reviewing updates helps practices remain compliant and reduces the risk of rejected claims.
10. Audit and Review Claims Regularly
Periodically audit submitted claims to identify errors, patterns in denials, or underpayment. Adjust documentation, coding, and workflows as needed to maintain accuracy and optimize reimbursement consistently.
Medicare Reimbursement in Teledermatology Billing
Medicare’s temporary telehealth flexibilities under the Public Health Emergency have expired, and pre-pandemic rules have been reinstated. These changes have significant implications for teledermatology reimbursement:
- Home-based telehealth visits are no longer reimbursed. Patients must be seen at approved originating sites, such as clinics, hospitals, skilled nursing facilities, or designated rural locations.
- Audio-only visits are largely restricted; video-based telehealth is now required.
- Geographic restrictions and provider eligibility rules have returned, limiting which providers and locations qualify for telehealth reimbursement.
- Documentation and workflow adjustments are essential to ensure compliance, including using the correct Place of Service (POS) codes and telehealth modifiers.
Exceptions remain for behavioral health, end-stage renal disease (ESRD), and acute stroke care, which retain permanent telehealth flexibilities, including coverage for home-based and audio-only visits.
For dermatology practices, adherence to these updated rules is critical to maintain Medicare reimbursement, ensure compliance, and safeguard patient access to telehealth services.
Commercial Reimbursement in Teledermatology Billing
Commercial payer policies for teledermatology vary widely, and reimbursement rules may differ from Medicare’s post-October 2025 restrictions. Dermatology practices should consider the following:
- Plan-Specific Coverage: Eligibility for teledermatology services depends on the insurer, plan type, and state regulations. While some commercial plans continue to permit home-based telehealth, others require visits to approved facility-based originating sites.
- Technology Requirements: Most commercial payers mandate synchronous two-way audio-video communication. Audio-only or asynchronous visits are generally restricted or non-covered, except in limited circumstances.
- Modifiers and Place of Service (POS) Codes: Accurate application of telehealth modifiers and POS codes is essential to ensure proper claims processing and reimbursement.
- Documentation Standards: Insurers often enforce strict documentation requirements, including medical necessity, patient consent, and detailed visit notes, particularly for higher-level evaluation and management (E/M) services.
- Variability Across Payers:
- UnitedHealthcare (UHC): Offers expanded telehealth coverage, including home-based visits for certain services, though coverage may vary by state.
- Cigna: Aligns Medicare Advantage plans with 2025 Medicare restrictions; coverage for commercial plans may differ and requires ongoing verification.
- Aetna: Requires video-based visits; audio-only or asynchronous telehealth services are largely limited.
- Blue Cross Blue Shield (BCBS): Policies differ by state plan; some continue to allow home-based telehealth, while others adhere to Medicare-originating site restrictions.
To ensure compliant and reimbursable teledermatology services, practices must verify payer-specific policies, apply correct modifiers and POS codes, and maintain thorough documentation.
Critical Billing and Reimbursement Strategies
Getting reimbursement right requires more than understanding rules; it requires building systems that implement them consistently.
Key strategies include:
1. Code Selection Based on Time or Complexity
Medicare E/M codes now allow time-based coding, giving flexibility but also creating risk for errors. Establish a protocol where clinical staff documents start and end times for each encounter, including all activities performed that day. Billing teams can then select the appropriate code, reducing undercoding or overcoding risks.
2. Modifier Accuracy
For Medicare, modifier 95 signals telehealth. Even with the 2025 CPT telehealth codes (98000-series), verify payer-specific requirements. Claims missing a required modifier can be denied as “coding errors,” impacting reimbursement.
3. Documentation Depth Drives Reimbursement
The level of medical decision-making (MDM) must match your billing code. For example, a level 3 E/M visit requires detailed documentation of history, differential diagnoses, treatment options, or complex medication management. Superficial notes limit reimbursement regardless of visit length.
4. Define In-Person vs. Virtual Criteria
Establish clear guidelines for which cases are appropriate for telehealth versus in-person visits. This not only protects patient safety but also creates a defensible audit trail for medical necessity. Overreliance on virtual visits without justification can trigger payer scrutiny.
5. Audit Coding Periodically
Review a sample of claims quarterly to identify undercoding, denials, or unusually low reimbursements. Audits reveal patterns in workflow or documentation issues and help optimize revenue.
6. Prepare for Payer-Specific Audits
Teledermatology claims are increasingly subject to post-payment audits. Maintain comprehensive documentation supporting every claim: coding accuracy, medical necessity, and compliance with payer policies. Being prepared turns audits into an opportunity to demonstrate accountability rather than a risk.
CPT Codes for Teledermatology Billing
Practices must carefully select codes based on the visit type, payer acceptance, and documentation requirements.
| CPT Code | Description | When to Use | Payer Acceptance Notes |
| 98000-98007 | Synchronous video telehealth visits for new and established patients (various complexity levels) | Use for standard video visits where telehealth-specific codes are accepted | Adoption varies by payer. Some commercial payers accept immediately; Medicare has limited adoption, mostly experimental or in select programs |
| 98008-98015 | Extended telehealth services, remote patient management, or high-complexity telehealth consult | Use for complex virtual consults or chronic care monitoring when the payer accepts | limited real-world use; verify each payer’s policy before billing. |
| 99202-99215 | Traditional office/outpatient E/M codes | Use if the payer does not accept 98000-series codes | Most payers still accept these codes for telehealth. Apply modifier 95 and correct the POS code (usually POS 02 for facility-based telehealth). |
| G2010 | Remote evaluation of patient-submitted images | For a brief review of images by established patients | Commonly accepted; payer-specific rules may apply. |
| G2012 | Brief telephonic or digital check-ins (5-10 min) | Quick follow-ups with established patients | Payers vary; mostly accepted for established patients. |
| RPM / CCM codes | Remote patient monitoring / chronic care management | For ongoing monitoring between visits | Widely accepted; verify documentation and payer rules. |
| GQ modifier | Store-and-forward teledermatology | In states or plans where asynchronous care is reimbursed | Limited to specific payers or states; always confirm coverage. |
Challenges and Strategies to Overcome in Teledermatology Billing
Telehealth billing presents operational challenges that require systematic approaches to overcome.
1. Payer Policy Changes
Insurance companies revise coverage policies with varying notice periods, creating unexpected claim denials.
Subscribe to payer alerts and policy updates. Designate personnel to review payer communications weekly and disseminate relevant changes to billing and clinical teams.
2. Documentation Standard Variation
Different payers impose different documentation requirements. Medicare emphasizes certain elements while commercial carriers and Medicare Advantage plans emphasize others.
Develop EHR note templates that systematically capture elements required across payers’ medical necessity, face-to-face and total encounter time, technology platform used, and documented patient consent. Standardized templates ensure consistency and completeness.
3. Telehealth Coding Knowledge Gaps
Billing staff proficient in in-person coding may lack familiarity with telehealth-specific coding requirements, resulting in errors.
Provide targeted training using decision trees that guide coding selection: “Is this patient new or established? What was the encounter duration?” Visual workflows reduce error rates compared to reliance on staff memory.
4. Established Patient Definition Variations
Medicare and certain commercial plans restrict audio-only services to established patients, but “established” definitions vary by payer.
Integrate eligibility verification into patient intake processes. Confirm prior in-person visits within defined timeframes (typically three years for Medicare) and document previous patient interactions. If patients don’t meet established criteria, schedule initial in-person visits or verify payer-specific policies for new patient telehealth exceptions.
5. Asynchronous Telehealth Billing Uncertainty
Photo-based consultations often lack clear reimbursement pathways due to variable payer policies.
Before implementing asynchronous workflows, verify each payer’s specific coverage policies. Identify which payers reimburse these services and which modifiers they require (such as GQ). Some practices provide asynchronous consultations as value-added services when coverage is unclear; others bill these services only when documentation confirms payer reimbursement.
Conclusion
Telehealth billing isn’t just a copy of regular billing with a video component. You need to understand the regulations, track what payers are doing, and have systems that work consistently. Practices that get this right access patients who like virtual visits, handle more cases faster, and keep more money. Practices that don’t deal with denials and revenue loss constantly.
The winning move is straightforward: know your payers’ rules, use EHR templates that capture what you need, check insurance before the visit, have clear billing steps your staff follow, train them well, and audit regularly.
