A doctor’s note request letter asks an employee to provide medical certification for their absence — but US employers must navigate a complex patchwork of federal and state laws about when this is permitted. While many employers routinely request doctor’s notes for any absence of three or more days, the legal reality is more nuanced: state paid sick leave laws, the FMLA, the ADA, and company policy all set different rules about when medical certification can be required.
Key Takeaways
- There is no federal law that requires an employee to provide a doctor’s note for sick leave — but employers can require it as a matter of policy, subject to state law limits.
- State paid sick leave laws in states like California, New York, Oregon, and Washington limit when employers can require documentation (typically only after 3 consecutive absences).
- FMLA certification is a separate, formal process with specific timelines and forms (DOL Form WH-380).
- ADA reasonable accommodations may require medical documentation, but the process is interactive and the request must be job-related.
- Never request diagnostic details — ask only for functional information (fitness to work, restrictions, expected duration).
Template 1: Standard Doctor’s Note Request (Absence of 3+ Days)
Use for a general absence where company policy requires documentation after a certain number of days.
Subject: Request for Medical Documentation — Absence [Dates]
Dear [Employee Name],
As you have been absent from work for [X] days, our company policy requires medical documentation to support your absence.
Please provide a note from your healthcare provider that includes:
- The date(s) you were seen or treated
- A statement that you were unable to work due to a medical condition
- The date you are cleared to return to work
You do not need to provide details of your diagnosis or specific medical information beyond what is needed to support your absence.
Please submit this documentation to [HR Contact / Manager Name] by [Date — typically within 5 business days of the request].
If you have difficulty obtaining a doctor's note (e.g. due to cost, access, or telehealth limitations), please let us know so we can discuss alternatives.
Best regards,
[Your Name]Keep the request narrowly focused on what the company actually needs. Asking for diagnosis details creates liability under the ADA and state privacy laws.
Template 2: Request Under State Paid Sick Leave Law (Compliant Wording)
Some states strictly limit when employers can require documentation. Use this wording for states with paid sick leave laws.
Subject: Documentation Request — Paid Sick Leave — [Dates]
Dear [Employee Name],
Under [State]'s paid sick leave law, we may request documentation to support your sick leave usage when the absence exceeds three consecutive days.
To comply with this requirement, please provide one of the following:
- A signed note from your healthcare provider
- A pharmacy record showing a prescription was filled during the absence period
- Other reasonable documentation that confirms you needed time off for a medical reason
If you used paid sick leave for a purpose other than your own medical needs (e.g. to care for a family member), you may provide documentation that supports that purpose instead.
Please submit this to [HR Contact] by [Date — typically 30 days from return to work, depending on state law].
You are not required to provide details about your specific medical condition.
Best regards,
[Your Name]State paid sick leave laws in California, Colorado, Connecticut, Maryland, Massachusetts, Michigan, Minnesota, Nevada, New York, Oregon, Rhode Island, Vermont, and Washington generally require the employer to accept alternative documentation (not just a doctor’s note) and prohibit requiring a note for short absences.
State-by-state documentation rules for paid sick leave:
| State | Documentation can be required after | Notes |
|---|---|---|
| California | 3 consecutive days | Cannot require a note for shorter absences; must accept alternative docs |
| New York | 4 consecutive days | Cannot specify the provider must be a doctor (nurse practitioner OK) |
| Oregon | 3 consecutive days | Cannot require the note to specify the reason for the absence |
| Washington | 3 consecutive days | Employer pays cost of documentation if it’s required |
| Massachusetts | 5 consecutive days | Cannot require a note for fewer than 5 consecutive days |
| Colorado | 3 consecutive days | Must accept alternative documentation |
| Connecticut | 3 consecutive days | Must accept a signed written statement from the employee as sufficient |

Template 3: FMLA Medical Certification Request
When an employee’s absence qualifies or may qualify for FMLA leave, a formal certification process applies.
Subject: FMLA Medical Certification Request
Dear [Employee Name],
Your absence beginning [Start Date] may qualify for leave under the Family and Medical Leave Act (FMLA). To designate this absence as FMLA leave, we need you to complete the attached medical certification form.
Please provide the following:
- [DOL Form WH-380-E (Employee's Certification - Employee's Own Serious Health Condition) / DOL Form WH-380-F (Family Member)] completed by your or your family member's healthcare provider
- The form should state the medical facts, the expected duration, and any planned treatment schedule
**Timeline:**
- You have **15 calendar days** from today to return the completed certification
- If you cannot meet this deadline, please let us know so we can discuss an extension
- Failure to return the certification within the allowed timeframe may result in the denial of FMLA leave for this absence
**Confidentiality:**
Your medical certification will be kept confidential and shared only with those who need to know for leave administration purposes.
The certification form is attached. Please return it to [HR Contact] by [Date].
Best regards,
[Your Name]FMLA certification has strict timelines under 29 CFR 825.305 — the employee must be given at least 15 calendar days to return the certification. The employer cannot require a second or third opinion unless using the formal FMLA dispute process.
Template 4: Return-to-Work Clearance Request
For absences where the employer wants confirmation the employee is fit to return — particularly in safety-sensitive roles.
Subject: Return-to-Work Clearance — [Employee Name]
Dear [Employee Name],
As your absence was related to a medical condition, we require clearance from your healthcare provider before you return to work.
Please ask your provider to complete the attached Return-to-Work Clearance form, which covers:
- Confirmation that you are fit to perform the essential functions of your role
- Any work restrictions or accommodations you may need
- The expected duration of any restrictions
Once we receive and review the clearance, we will confirm your return date and any [reasonable accommodations](/blog/disability-leave-equality-act-2010/) or adjustments needed.
Please submit the completed form by [Date].
Best regards,
[Your Name]Return-to-work clearance is common in safety-sensitive roles (manufacturing, healthcare, transportation) but should be used carefully in office environments. The ADA requires any medical inquiry to be job-related and consistent with business necessity.
Template 5: ADA Reasonable Accommodation Documentation Request
When an employee requests ongoing accommodation for a disability.
Subject: Documentation Request — Reasonable Accommodation
Dear [Employee Name],
Thank you for requesting a reasonable accommodation under the Americans with Disabilities Act (ADA). To evaluate your request, we need some documentation from your healthcare provider.
Please ask your provider to complete the attached form, which asks:
- That you have a disability as defined by the ADA
- How the disability affects your ability to perform the essential functions of your role
- What accommodation would help you perform those functions
- The expected duration of the need for accommodation
You do not need to provide your specific diagnosis or detailed medical history.
Once we receive the documentation, we will schedule an interactive discussion to review your request and explore accommodation options.
Please submit the documentation by [Date].
Best regards,
[Your Name]The ADA interactive process is collaborative — the employer cannot demand a specific form of documentation if the employee offers reasonable alternative evidence. See the EEOC’s guidance on disability-related inquiries for detailed rules.
Legal Limits on Doctor’s Note Requests
Federal law:
- FMLA: Formal certification process with 15-day deadline; second/third opinions are permitted but the employer pays
- ADA: Documentation requests must be job-related and consistent with business necessity; no blanket “note for any absence” policies
- HIPAA: Employers cannot receive detailed medical records from providers without employee authorization
State law common restrictions:
- Cannot require a note for absences shorter than a state-specific threshold (typically 3 days)
- Must accept alternative documentation (pharmacy records, self-certification)
- Employer may be required to pay for the cost of obtaining documentation in some states (e.g., Washington, Oregon)
- Documentation requests cannot be used punitively or to discourage sick leave use
Best practices:
- Only request documentation when it is truly needed to verify the absence or plan a return
- Never ask for a diagnosis — ask only about functional limitations
- Accept alternative documentation when state law permits
- Apply documentation policies consistently across all employees
FAQ
Can a US employer require a doctor’s note for a single-day absence?
It depends on state law. In states with paid sick leave laws (California, New York, Oregon, Washington, Massachusetts, etc.), employers generally cannot require documentation for absences shorter than 3-5 consecutive days. In states without paid sick leave laws, employers can require a note as a matter of policy — but the policy must be applied consistently and not discriminatorily.
Can I fire an employee who refuses to provide a doctor’s note?
If the employer’s policy requires documentation and the employee fails to provide it, the absence may be treated as unauthorised, potentially leading to disciplinary action. However, in states with paid sick leave laws that limit documentation requirements, enforcing a stricter policy could violate state law.
Do I need to pay for the doctor’s note?
In most states, no — the employee pays for their own medical visit. In Washington and Oregon, the employer must pay the cost of obtaining documentation if it is required as a condition of using paid sick leave. Check your state’s specific law.
What if the employee can’t afford or access a doctor?
Consider accepting alternative documentation (pharmacy records, urgent care discharge papers, telehealth provider notes). Forcing an uninsured or low-wage employee to pay for a doctor’s visit to comply with a note policy can create legal exposure under state paid sick leave laws and public policy.
How long should I keep medical documentation on file?
Medical documentation related to FMLA, ADA, or illness absences should be kept in a confidential medical file, separate from the personnel file. The ADA requires these records to be kept confidential. Retention periods vary by state and federal law — generally 3-5 years after the end of employment.
