How to get a return‑to‑work clearance after illness

Returning to work after an illness can be stressful, but getting proper medical clearance (often called a “doctor’s note” or “fitness-for-duty certificate”) helps protect both you and your employer. It ensures you’re physically ready to return to work and helps your employer comply with essential U.S. workplace regulations like the Family and Medical Leave Act (FMLA), the Americans with Disabilities Act (ADA), and the Health Insurance Portability and Accountability Act (HIPAA).

Do I really need a doctor’s note to return after an illness?

Whether you need a doctor’s note depends on:

• Company policy – Many employers require documentation for absences longer than 3–5 days.
• Health condition – For communicable diseases (like influenza, COVID-19, or pneumonia), employers may request a fitness-for-duty note in line with the Occupational Safety and Health Administration (OSHA) guidance.
• Legal protections:
  • FMLA – Employers can request certification for serious health conditions.
  • ADA – Fitness-for-duty notes help support reasonable accommodation requests.
  • HIPAA – Limits disclosure to only what’s necessary for job-related purposes.

When in doubt, ask your HR department about what’s required.

Who might need a return-to-work clearance?

While anyone may be asked for a return-to-work note, employees in these groups are more commonly affected:

1. Public-facing or safety-critical roles
   Healthcare workers, EMTs, and nurses often need clearance before returning to work due to patient safety concerns.

Teachers and daycare staff may also require a note to reduce transmission risks in close-contact environments.

Food service and hospitality workers may need to provide documentation following gastrointestinal or respiratory illnesses due to local health regulations.

2. Employees returning from extended medical leave (14+ days)
   Long absences may trigger FMLA protocols. Employers can request a fitness-for-duty note to confirm you’re able to perform essential job duties.
   
3. Ongoing treatments or recoveries
   Those undergoing chemotherapy, radiation, or cardiac rehab often need medical clearance to safely return and may require modified duties while on the job.
   
4. Medication changes with potential side effects
   If you’re taking CNS-depressant medications (such as benzodiazepines, opioids, and some antidepressants), a return-to-work note may include temporary work restrictions based on FDA safety guidelines.
   
5. Employees with disabilities returning under the ADA
   When returning from disability-related leave, employers can request a medical clearance note to help determine any necessary accommodations and ensure workplace safety.
   
6. Seasonal or federal workers (e.g., USPS)
   Federal agencies like the Postal Service may require documentation if there is a reasonable belief that the employee cannot safely perform their job.

Where can I get a doctor’s note to return to work?

There are many reliable ways to get a doctor’s note:

• Primary care provider – Best for complex or long-standing conditions.
• Urgent care clinics – Offer fast, in-person evaluations and same-day notes.
• Telehealth services (like Klarity Health) – Convenient for mild to moderate conditions and offer convenience with quick turnaround.

How to get an online return-to-work clearance after illness 

1. Choose the right telehealth platform

Look for platforms that provide:

• HIPAA-compliant virtual visits
• Licensed U.S. providers
• Notes for work, school, or FMLA purposes

Platforms like  Klarity Health offer quick and convenient appointments that can provide you with the doctor’s note or form you need to return to work safely. 2. Book and prepare for the visit

• Create an account and select “doctor’s note” as your visit reason
• Describe your illness, job duties, and any ongoing limitations
• Choose how you want to meet with your provider, such as video or phone. 

3. Receive and review your clearance

• The provider will evaluate your condition and you’ll receive a signed PDF with relevant details, including a return date and any necessary restrictions, within minutes to 24 hours

4. Submit the note to your employer

• Send it by email, upload to an HR portal, or provide a printed copy
• Follow up to confirm it meets requirements

What to expect from an in-person clearance

If your HR says that telehealth isn’t preferable, which can happen with serious conditions or if you have a safety-sensitive role, an in-person visit with a physical exam may be necessary. These exams typically include:

• Physical evaluations
• Vital signs, mobility assessments
• Diagnostic tests ( like ECGs or blood labs)
• Functional capacity evaluations (FCEs) to assess strength and job readiness

What should a return‑to‑work clearance note include?

A complete note usually must include :

• Employee name
• Date of exam
• Condition summary 
• Functional status (e.g., full duties or specific limitations with timeframes)
• Return-to-work date
• Provider credentials (name, license, contact info, signature)

 It’s important to note that your doctor only needs to share what’s necessary for work purposes. They should never provide your full medical records and aren’t required to share your diagnosis, test results, treatment plans, or other details of your condition. According to FMLA regulations (29 CFR §825.312), the provider must give documentation that confirms whether you can perform essential job functions. Additionally, a licensed provider must sign and date the letter.
