You called in sick, or you need time off for a medical problem, and your employer wants paperwork from a doctor. Can they insist on it? In most cases, yes. But what they can ask for, how quickly you have to provide it, and what happens if you can’t get a note depend on which law covers your leave.
This guide explains how doctor’s note requirements work for Indiana employees, what changes when the Family and Medical Leave Act (FMLA) applies, and the extra rules for commercial drivers.
The short answer
Indiana does not have a general law that limits when a private employer can ask for a doctor’s note. Indiana also has no statewide paid sick leave law for private employers, so most sick-day rules come from your employer’s own policy.
That means an employer can usually require documentation for an absence, as long as it:
- applies the rule consistently to everyone, and
- does not use it to interfere with leave you are legally entitled to, or to single you out because of a disability, pregnancy, or another protected characteristic.
When your absence is covered by the FMLA or involves a disability, federal law limits what the employer can demand.
When FMLA applies: medical certification
If you are eligible for FMLA leave (see who qualifies for FMLA in Indiana), your employer can ask you to provide a medical certification from a health care provider. This is the FMLA’s version of a doctor’s note, and federal regulations set the rules.
How long you have. Your employer must give you at least 15 calendar days to return the certification, unless that is not practicable despite your diligent, good-faith efforts (29 C.F.R. § 825.305).
If the form is incomplete. Your employer must tell you in writing what is missing and give you seven calendar days to fix it, when practicable.
What the certification can include. The certification covers facts such as when the condition started, how long it is expected to last, and why you are unable to work or need to care for a family member (29 C.F.R. § 825.306). Your employer is not entitled to your full medical records.
Second opinions. If your employer has reason to doubt the certification, it can require a second opinion, at its own expense, from a provider it chooses (but not one it regularly employs).
What happens if you don’t provide it. If you never return a requested certification, your employer may deny FMLA protection for that leave. That is why it matters to ask your provider early and keep a copy of everything you submit.
When a disability is involved: the ADA
If your absence relates to a disability, the Americans with Disabilities Act limits medical questions. Once you are employed, an employer may make disability-related inquiries or require medical exams only when they are job-related and consistent with business necessity (42 U.S.C. § 12112(d)). Medical information must be kept confidential and stored separately from your personnel file.
A simple note confirming you were seen and when you can return is usually fine. A demand for your diagnosis for a routine sick day can cross the line. The EEOC’s guidance on disability-related inquiries and medical exams explains where it falls.
If you need ongoing time off or a modified schedule, you may also be entitled to a reasonable accommodation. See our guide to ADA accommodations in Indiana.
Special rules for commercial drivers
If you drive a commercial motor vehicle, federal safety rules add another layer. Interstate commercial drivers must hold a valid medical examiner’s certificate, and a driver whose ability to drive safely has been impaired by an injury or illness must be medically re-examined before returning to driving (49 C.F.R. § 391.45).
In practice, that means a trucking or delivery employer can require medical clearance before you get back behind the wheel after certain illnesses or injuries. That requirement is about safety rules. It does not cancel your FMLA or ADA rights, and it cannot be used as an excuse to retaliate against you for taking protected leave.
What if you can’t get a doctor’s note?
Sometimes you are sick for a day or two and never see a doctor. Some practical steps:
- Read the policy. Many policies only require a note after a set number of consecutive days.
- Use telehealth or urgent care. A short visit can usually produce a dated note.
- Ask in writing for more time if you are waiting on an appointment, and keep the message.
- Tell your employer if the absence may be FMLA leave. You do not have to say “FMLA,” but you must give enough information for your employer to know the leave may qualify.
Signs your employer may be crossing the line
- Requiring notes only from you, or only from workers who are pregnant, older, or have a known disability
- Demanding your diagnosis or full medical records for an ordinary absence
- Refusing to accept a timely FMLA certification, or not giving you time to fix it
- Disciplining or firing you soon after you submit medical documentation
Any of these can support a claim for FMLA interference, disability discrimination, or retaliation. If you were fired after a medical absence, read your rights after being fired during medical leave.
Doctor’s notes and your employer’s sick leave policy
Because Indiana has no statewide paid sick leave law for private employers, the details usually come from your employer’s own policy. Many policies require a note only after a certain number of consecutive sick days, or only when an absence falls next to a weekend or holiday. Others require a note for any unscheduled absence.
Whatever the policy says, it should be written down and applied the same way to everyone. If your employer suddenly starts demanding notes from you but not from coworkers, write down when the change started and what happened just before it. Our guide to Indiana sick leave laws covers how these policies usually work.
Intermittent leave and recurring absences
If you have a chronic condition such as migraines, diabetes, or a back injury, you may need time off in short, unpredictable stretches. Under the FMLA, one certification can cover this intermittent leave if your provider estimates how often flare-ups happen and how long they last.
Your employer generally cannot demand a brand-new doctor’s note for every covered flare-up. It can ask for recertification in limited situations, typically no more often than every 30 days and in connection with an absence, or sooner if the circumstances described in the original certification change significantly.
Leave to care for a family member
When you take FMLA leave to care for a spouse, child, or parent with a serious health condition, the certification comes from their health care provider, not yours. It should explain the family member’s condition and why your care is needed, whether that is physical care, transportation to treatment, or psychological comfort.
Mental health conditions
Anxiety, depression, PTSD, and other mental health conditions can qualify for FMLA leave and ADA protection. A therapist, psychologist, or psychiatrist can complete the certification. You do not have to share therapy notes. See our guide to FMLA for mental health conditions in Indiana.
Who gets to see your medical information
Medical information you give your employer must be kept confidential. Under the ADA and the FMLA regulations, medical records belong in a separate, confidential file, not in your regular personnel file, and should be shared only with people who need to know, such as a supervisor who needs to know about work restrictions.
If medical details you gave HR are being discussed by coworkers, write down who said what and when, and raise it in writing.
Step by step: when your employer asks for a doctor’s note
- Get the request in writing, including the deadline and what the note must say.
- Ask your provider early. Many offices need several days to complete forms.
- Check what you are sending. Make sure dates, restrictions, and expected return dates are filled in.
- Submit it in a way you can prove, such as email or an HR portal, and keep a copy.
- Follow up if you do not hear back within a few days.
- Ask for more time in writing if your provider is delayed.
Common employer mistakes
- Treating a late note as a reason to fire someone when the FMLA allowed more time
- Rejecting a certification without saying what was wrong or giving time to fix it
- Requiring a note for every intermittent flare-up already covered by a certification
- Asking for a full diagnosis or medical records for an ordinary absence
- Letting a direct supervisor call the employee’s doctor
Frequently asked questions
Can my employer require a doctor’s note for one sick day in Indiana?
Generally yes, if its policy applies the rule to everyone. Indiana law does not prohibit it for private employers.
Can my employer ask what my diagnosis is?
For FMLA leave, the certification covers relevant medical facts, not your full records. Under the ADA, questions must be job-related and consistent with business necessity, and the answers must be kept confidential.
How long do I have to turn in FMLA paperwork?
At least 15 calendar days after your employer asks, and seven days to fix an incomplete form, when practicable.
Can my employer call my doctor?
For FMLA certification, your employer may contact your provider only to authenticate or clarify the form, and not through your direct supervisor.
Does a note from a telehealth visit count?
Usually, yes. A note from a licensed health care provider after a telehealth visit is generally treated the same as one from an in-person visit, unless your employer’s policy reasonably requires something specific.
Can I be fired for not having a doctor’s note?
If the absence is not protected leave, an employer can usually enforce its attendance policy. If the absence is FMLA leave or relates to a disability, the rules above apply, and a firing may be unlawful.
