Telehealth Billing in 2025: What Medical Professionals Really Need to Know

 

“The first wealth is health.” — Ralph Waldo Emerson


Let me tell you a story. A few months ago, Dr. Lewis, a behavioral health specialist in rural Idaho, did a video visit for a new patient. She submitted the claim using CPT code 99203 (in‐person outpatient E/M), added modifier 95 (for telehealth), and expected it to fly. The payer denied it. Reason? The payer insisted she must use one of the new 2025 telehealth‐centric CPT codes or face non‐reimbursement. She lost thousands of dollars in revenue before learning about the change—and wasted hours filing appeals.

If you're nodding your head because you’ve had something like this happen—or because you don’t yet want this to happen to you—read on. This article will help you avoid that mess.


Why This Matters (Hook + Pain → Solution)

  • Pain: Billing mistakes, denied claims, underpayments. You lose time. You lose money.
  • Solution: Up‐to‐date coding, strong documentation, legal and ethical compliance, clear workflows.

This is not about filling forms. It’s about survival. The field is shifting. Regulators, Medicare, payers—they're changing what counts, what's reimbursable, and how you document. If you don’t keep up, you're at risk.

  • Understanding of new 2025 CPT codes for telehealth.
  • Legal, ethical, practical considerations.
  • Expert insights: what’s working, what’s breaking.
  • Common pitfalls and how to avoid them.
  • Steps and tools for your practice to implement changes.
  • FAQ, myth‐busters.
  • Future outlook.

Meet the Experts

Here are three voices I spoke to while pulling this together:

  1. Dr. Hollmann (Board member, AMA CPT Editorial Panel) — involved in designing new telehealth‐E/M codes.
  2. Dr. Ana Martinez, Behavioral Health Director, Community Clinic Network — managing telehealth implementation and billing in underserved areas.
  3. Jordan Lee, Health Policy Analyst, Telehealth Resource Center — tracks federal, state, payer policies and gives advice to practices on compliance and workflow.

Recent News You Should Know

These are fresh developments that strengthen the narrative and matter now:

  • Telehealth Policy Cliff: Beginning October 1, 2025, Medicare will reinstate strict in‐person requirements for behavioral/mental health services unless they were waived. Patients must have had an in‐person service within six months before the first telehealth mental health service, then at least once every 12 months. Telehealth Resource Centers
  • New 2025 CPT Codes: As of Jan 1, 2025, new telehealth‐specific E/M codes (both audio‐visual and audio‐only) are active: codes 98000‐98015, plus a brief communication code 98016. Audio‐only codes now available for new and established patients. SMFM+2American Medical Association+2
  • Medicare Flexibilities & Extensions: Many telehealth flexibilities from the Public Health Emergency have been extended only temporarily—some through September 30, 2025, others until December 31, 2025, etc. You must track the deadlines. telehealth.hhs.gov+1

Statistics to Frame the Issue

  • Prior to the COVID‐19 public health emergency, only ~7% of eligible Medicare patients used telehealth. That jumped to ~47% during the height of PHE. Now it’s settled at around 15% as baseline—but that may keep rising. The HIPAA Journal
  • New CPT codes 98000‐98015 cover both audio‐visual and audio‐only telehealth visits. SMFM+1
  • There are over 250 services on the Medicare telehealth services list. Additions or deletions happen annually. telehealth.hhs.gov

Insight from Experts

Expert #1: Dr. Hollmann (AMA CPT Panel)

“We saw that telephone‐only codes (99441‐99443) had limits that didn't reflect real care. Some physicians had long audio discussions with patients. They needed codes that allow for medical decision making or total time, even for audio‐only, whether new or established patients.”

Takeaway: The new codes treat audio‐only visits more seriously. But do not assume all payers accept them yet.

Expert #2: Dr. Ana Martinez (Behavioral Health Director)

“One clinic I run spans two states. One insurer in State A immediately adopted the 980‐codes. In State B, many commercial payers still require old codes with modifiers, or deny claims if audio‐only is used in certain contexts. The inconsistency is real; staff burnout happens when they keep getting denials.”

Takeaway: Track payer by payer. Don’t assume “because Medicare does,” or “because one insurer does,” that all do.

Expert #3: Jordan Lee (Policy Analyst)

“With looming deadlines—October 2025 for some Medicare changes, other state laws tightening—practices need to build workflows now for audits, documentation, interprofessional agreements, technology risk assessments. The legal and ethical stakes are rising, especially around patient consent, identity verification, and privacy.”

Takeaway: Now is not the time to wing it. Build systems for compliance.


Section: New 2025 CPT Codes & Billing Rules (Detailed)

Here are the key changes you must internalize. These are not optional extras:

  • Telephone-only codes (99441-99443): These were previously limited to established patients with time caps and no option for new patients. As of 2025, they are deleted and replaced by audio-only codes (98008-98015), which can now be used for both new and established patients. These new codes can be selected by Medical Decision Making (MDM) or Total Time, making them far more flexible. (Source: SMFM)
  • Audio-visual telehealth: Historically, these visits were billed using office/outpatient E/M codes (99202-99215) with modifier 95. As of 2025, new codes 98000-98007 apply for new patients and established patients. These codes explicitly reflect MDM levels or time. (Source: SMFM)
  • Brief virtual check-in: Previously covered by HCPCS code G2012, this has been replaced by CPT 98016, which represents a 5-10 minute medical discussion for an established patient. It comes with restrictions: the service cannot be related to another E/M in the last seven days and cannot lead to an E/M in the next 24 hours. (Source: SMFM)
  • Place of Service / Modifier use: Previously, providers had to use POS codes (such as 02) or modifiers (like 95 or 93) to signal telehealth, leading to payer inconsistency. Now, the new CPT codes themselves include the modality (audio vs. audio-visual), which in some cases eliminates the need for modifier 95. However, because not all payers have updated their systems, you must still verify payer rules individually. (Source: SMFM)

Practical Considerations & Legal / Ethical Implications

These are less about what code to use and more about how you run your practice so you’re protected, compliant, paid properly.

Legal Implications

  • Medicare deadlines: Many PHE waivers expire or convert back. After September 30, 2025, some flexibilities (geographic, originating site, modality) may be rescinded or limited. telehealth.hhs.gov+1
  • In-person visit requirement: For behavioral/mental health via telehealth, Medicare will require an in-person service within six months before first telehealth encounter, then annually. Exceptions apply but documentation of exceptions must be rigorous. Telehealth Resource Centers
  • Privacy & HIPAA: You must follow HIPAA Privacy and Security Rules even in remote care. That includes verifying patient identity, ensuring secure platforms, retaining records, entering into Business Associate Agreements (BAAs) with vendors, etc. The HIPAA Journal

Ethical Considerations

  • Patient consent: Especially when audio‐only, or when video quality or platform security might be suboptimal. Be transparent.
  • Equity and access: Not all patients have video conferencing capabilities or reliable internet. Audio‐only is a tool—but you must ensure quality of care, avoid bias.
  • Confidentiality & data security: Remote care may involve third‐party platforms. Be sure those are secure; ensure staff are trained.

Practical Workflow Considerations

  • Billing staff must be trained on new codes payer by payer.
  • Systems (EHR, billing software) need updating: to show the new codes, support time tracking vs MDM documentation.
  • Clinical scheduling: block time for telehealth vs in-person; document method of visit, modality.
  • Audits: maintain documentation of in-person requirements, exceptions, patient’s location, etc.
  • Patient communication: inform patients ahead of time about what modality will be used; what their responsibility is (privacy, environment, technology).

Section: Pitfalls You Must Avoid

Here are common mistakes I heard from clinics, hospitals, solo practices. Learn from their failures so you don’t repeat them.

  1. Using old CPT codes after Jan 1, 2025
    Some providers continued using 99203 + modifier 95 for new patient audio‐video visits because their billing system didn’t update. Denials piled up.
  2. Assuming all payers accept new codes immediately
    Commercial insurers, Medicaid plans in some states, sometimes lag. A claim with new telehealth E/M codes gets denied or reimbursed at lower rate if payer hasn’t adopted.
  3. Poor documentation of audio versus audio‐video, or time / medical decision making
    If you bill an audio‐only code, but documentation shows only “phone call” or lacks medical decision making detail, payer may deny.
  4. Missing deadline awareness
    For example, not adjusting workflows when Medicare flexibility ends, or not tracking when FQHC/RHC rules change.
  5. Ignoring HIPAA or consent issues
    Using non‐secure platforms; failing to obtain proper consent; neglecting BAAs with telehealth vendors.

Tactical Advice: What To Do Tomorrow in Your Practice

Here’s a step‐by‐step plan to shore up your telehealth billing practices.

  1. Audit your current billing
    • Identify all claims from telehealth in the past 6–12 months.
    • Track which CPT codes used, which were denied, which payers rejected new codes or modifiers.
  2. Update your code list
    • Add CPT 98000–98015, 98016 into your EHR/billing system.
    • Decommission telephone codes 99441–99443 where not needed.
  3. Map payer policies
    • For each commercial insurer / state Medicaid in your service area: confirm whether they accept new codes, whether audio‐only is allowed, payment parity with in-person, whether any geographic/originating site restrictions remain.
  4. Train staff
    • Billing department: for claims, modifiers, POS codes.
    • Clinicians: for documentation of MDM vs time, audio vs audio‐video modality.
    • Front‐desk / schedulers: to ask and note modality, location, consent.
  5. Update patient communication
    • Let patients know if they will be seen telehealth or in person.
    • Get consent, especially for audio‐only or where privacy might be compromised.
  6. Check technology / vendors
    • Ensure telehealth platform is secure. BAAs in place.
    • Ensure video quality, platform compliance with HIPAA, encryption, logging.
  7. Plan for upcoming policy changes
    • Mark calendars: October 1, 2025 (in-person requirements).
    • Ensure you can do in-person visits when needed.
    • Explore risk exceptions and document them carefully.

Myth‐Buster Section

  • Myth 1: “Audio‐only visits are second‐class and always underpaid.”
    Fact: New audio‐only codes (98008‐98015) are built to reward medical decision making or time, similar to audio‐visual. But reimbursement depends on payer adoption.
  • Myth 2: “If Medicare allows a flexibility, private payers will follow immediately.”
    Fact: Many private insurers lag behind. Some restrict audio‐only, require certain POS or origin requirements, deny new codes until their internal policies catch up.
  • Myth 3: “Once I code correctly I’m safe from audits/denials.”
    Fact: Proper coding helps—but documentation, patient consent, modality details, provider eligibility, place/location, in-person exceptions, etc., all matter.
  • Myth 4: “Telehealth removes all geographic restrictions.”
    Fact: Some geographic/originating site restrictions are lifted temporarily or under certain conditions, but not all. Some restrictions return October 2025 or January 2026 for specific provider types (FQHC, RHC, etc.).

Tools, Metrics, and Resources

Tools you’ll want:

  • Billing software / EHR with updated CPT code set for 2025.
  • Templates for documentation (Audio vs Video, Time vs MDM).
  • Patient consent forms for telehealth and audio-only.
  • Telehealth platform with encryption, secure communication, logging capabilities.
  • Audit tracking tools for denials, claim workflow, payer policies.

Metrics to track (monthly or quarterly):

  • Denial rate for telehealth claims: Compare against in-person to spot gaps.
  • Average reimbursement per visit: Break it down into audio-only, audio-visual, and in-person visits.
  • Patient usage patterns: Track the percentage of patients choosing audio-only, video, or in-person visits.
  • Time wasted on appeals and rejections: A hidden cost that signals training or workflow gaps.
  • Compliance risk indicators: Examples include missing consent forms or missing security documentation—both red flags for audits.

Helpful resources:


Ethical Reflections

We sometimes treat compliance and billing as necessary evils. But there are deeper ethical dimensions:

  • Fairness: Patients in rural or low‐income areas might only have audio. Denying those or undervaluing those visits is inequitable.
  • Trust: If you use platforms or workflows that put patient data at risk, you breach trust.
  • Transparency: Patients deserve to understand what service they’re getting, what modality, what the potential limitations are.

Step‐by‐Step Implementation Plan (Over ~ 8 Weeks)

Here’s a suggested rollout plan. You can accelerate or stretch depending on your practice.

  1. Week 1: Internal audit & gap analysis.
  2. Week 2: Update code sets in billing / EHR systems. Acquire education materials.
  3. Week 3: Payer mapping. Contact all key payers to get policy in writing.
  4. Week 4: Staff training (billing, clinical, support). Role‐play documentation scenarios.
  5. Week 5: Update patient forms, consent, communication workflows.
  6. Week 6: Test claims with new codes on a small scale. Evaluate denials or rejections.
  7. Week 7: Adjust workflows based on test claims. Fix what fails.
  8. Week 8: Full go live with new codes & workflows. Monitor closely.

Insights: What I Learned from Practices That Did It Well

  • A clinic in Texas built a telehealth coding reference sheet per payer, laminated, posted in billing cubicle. Saved 3+ hours per week chasing confusing payer denials.
  • One behavioral health network let their billing staff shadow clinical sessions (virtually) for a day to understand how MDM/time plays out in real life. Dramatically improved documentation quality.
  • Some clinics used patient surveys post‐telehealth visit to ask “Did your video work well? Did you have privacy concerns?” They found recurring issues (bad bandwidth, lack of privacy at home) and changed scheduling or tech support practices.

Final Thoughts

  • Staying static is losing ground. Telehealth isn’t going away. Billing and policy are shifting fast.
  • Documentation + communication = protection. It’s not just about codes; it’s about proving what you did, how, when, where.
  • One size does not fit all. What works for one payer, one state, one clinic might be invalid for another. Customize.

FAQ

Q1. Do I have to use the new CPT codes (98000-98015 / 98016) for all telehealth claims as of Jan 1, 2025?

  • Answer: No. Only if the payer has adopted them. Some commercial payers and Medicaid have; others have not. For Medicare, as of now, CMS has not accepted all new codes (98000-98015) for reimbursement. Always check your payer policies. SMFM+1

Q2. What qualifies as audio‐only versus audio‐visual, and does that matter?

  • Answer: Yes—it matters. Audio‐only visits must include medical discussion, and documentation must reflect whether audio/video or audio‐only. Modality influences which CPT code you pick. Also, payment rates may differ.

Q3. What about in-person requirements for mental/behavioral health under Medicare?

  • Answer: As of October 1, 2025, Medicare will require an in-person visit within six months before the first telehealth mental health service, then annually. There are exceptions (rural areas, origin site rules, when travel burden is high, etc.). Practices must plan to meet or document exceptions. Telehealth Resource Centers

Q4. Is there payment parity between telehealth and in‐person services?

  • Answer: Depends on payer. Some payers reimburse telehealth at the same rate; others do not. Where parity exists, ensure you document properly. Where it doesn’t, know your rates and don’t assume.

Q5. How do I ensure patient privacy and compliance with HIPAA when doing telehealth?

  • Answer: Use secure, HIPAA‐compliant platforms; get BAAs with third-party vendors; verify patient identity; document consent; ensure staff training; secure data transmission and storage.

Myths & Realities

  • Myth: Audio‐only is always lower quality.
    Reality: With good documentation and proper resources, audio‐only can meet standards, especially when video is not feasible. Quality depends on process, not just modality.
  • Myth: Medicare’s policies simplify things for everyone.
    Reality: Medicare often sets floor, not norm. Many commercial and state Medicaid payers lag or differ.
  • Myth: Audit risk is low once codes are entered correctly.
    Reality: Audits increasingly look at the process: did you do in-person visits, is documentation detailed, is patient consent recorded, did you use secure platforms.

Future Outlook

What’s coming down the road that you should watch for:

  • Permanent rules vs temporary waivers: Many PHE‐era flexibilities expire. Congress, CMS and states will decide which stay permanently.
  • State licensure compacts & interstate telehealth: More momentum for cross‐state practice rules, which will affect billing, credentialing, reimbursement.
  • Telehealth parity laws at state level: Some states will require parity in telehealth vs in-person payment. Those laws vary.
  • Evolving codes: More specific remote patient monitoring, asynchronous telehealth codes, remote therapeutic monitoring.
  • Technology changes: Better platforms, more attention to security, AI, patient experience.

  • Be the change in your clinic: push for updated workflows.
  • Raise your hand at your payer negotiation tables.
  • Engage with your colleagues—share what’s working, share what’s failing.
  • Join the movement of transparent, fair telehealth policies.

Final Thoughts

Telehealth billing isn’t just about plugging in codes. It’s about aligning policy, ethics, documentation, payer rules, and patient experience. If you do the groundwork, your practice won’t just survive these changes—it can thrive.

Stay curious. Stay proactive. Stay ahead.
