  • Issues like network disruptions, device malfunctions, and software glitches can hinder smooth communication between patients and doctors.
  • Poor-quality cameras, images, or lighting may affect the accuracy of diagnoses.

2. Limited Physical Examination

  • Telemedicine lacks the ability for hands-on diagnosis, making it difficult to assess certain medical conditions that require physical tests or touch-based evaluations.

3. Patient-Doctor Relationship

  • Virtual consultations may reduce rapport and trust, as some patients prefer in-person interactions for a better sense of connection and understanding.

4. Infrastructure & Accessibility Issues

  • Some patients, especially in rural or underserved areas, may lack access to high-speed internet or necessary digital devices for telemedicine appointments.

5. Security & Privacy Concerns

  • Ensuring electronic health record (EHR) security is a major challenge, as telemedicine platforms must comply with strict data protection regulations.

6. Legal & Policy Uncertainties

  • Malpractice liability in telemedicine remains unclear, as laws differ across regions.
  • Medicaid and private insurers have inconsistent reimbursement policies, making it uncertain whether telemedicine services will be covered.
  • Medicare telemedicine coverage is limited to specific rural areas, restricting access for many patients.

Some states require patients to consult with licensed practitioners within their geographical area, adding regulatory complexities.
