Few questions create more confusion for federal employees than this one:

“How much medical information am I required to give my employer?”

Whether you’re requesting reasonable accommodation, applying for FMLA, seeking sick leave, or dealing with a fitness-for-duty issue, the rules are not the same in every situation. And agencies frequently overreach — sometimes out of misunderstanding, sometimes out of habit, and sometimes out of convenience.

This guide breaks down exactly what you must provide, what you may provide, and what you should never provide, so you can protect both your privacy and your career.

The Golden Rule: Provide Only What the Law Requires

Federal agencies are entitled to functional information, not your personal medical history.

You do not have to give:

  • Your full medical records

  • Detailed diagnoses

  • Treatment notes

  • Medication lists

  • Therapy summaries

  • Mental health history unrelated to job performance

  • Genetic information

  • Family medical history

These are private, protected, and legally off-limits in most contexts.

The federal employer’s right to medical information is always limited and purpose-specific.

Scenario 1: Reasonable Accommodation

When requesting an accommodation, you must provide enough medical information to establish:

  1. You have a physical or mental impairment

  2. The impairment substantially limits a major life activity

  3. You have functional limitations tied to essential job duties

  4. The requested accommodation would help you perform those duties

You do not need:

  • Diagnosis

  • Etiology

  • Full medical charts

  • Imaging reports

  • Lab results

Agencies often pretend they need these — they don’t.

The correct approach is a functional statement from your provider describing:

  • Limitations

  • Duration

  • Job impact

  • Recommended accommodations

Nothing more.

Scenario 2: Sick Leave Requests

For short sick-leave absences, agencies typically may request only:

  • A brief medical note

  • Confirmation that you were incapacitated

  • Dates you were seen or treated

They may not demand:

  • Detailed diagnosis

  • Entire medical file

  • Records explaining the condition in depth

For extended sick leave (generally 3+ days), a short certification is allowed — but still limited to confirming incapacity and expected recovery.

Scenario 3: FMLA

FMLA documentation is more structured and uses the WH-380 or equivalent form.

What you must provide:

  • Confirmation of a serious health condition

  • Basic description of functional incapacity

  • Expected duration

  • Intermittent or continuous leave details

What you do not need to provide:

  • Diagnosis

  • Underlying medical history

  • Medications

  • Treatment plans

The provider can write “Condition A,” “Medical Issue,” or simply describe functional limitations.

Scenario 4: Fitness for Duty (FFD)

FFD exams can feel intrusive — but even here, limits apply.

Agencies must have objective evidence that:

  • You are unable to perform essential functions, or

  • You pose a direct threat

What they may request:

  • Functional assessment

  • Information related to specific performance or conduct concerns

  • Clarification about ability to perform essential duties

What they cannot demand:

  • Entire medical history

  • Broad mental health records

  • Drug/alcohol history unless relevant to safety concerns

  • Non-job-related medical data

FFD exams must be necessary and narrowly tailored, not fishing expeditions.

Scenario 5: Workers’ Compensation (OWCP)

OWCP is medical-heavy — but this is between you and OWCP, not your employer.

Your agency does not receive:

  • Diagnosis details

  • Imaging

  • Treatment notes

  • Medication lists

OWCP documentation does not go into your OPF.

If HR claims they “need” full medical records to process your claim, they are wrong.

Scenario 6: Performance or Misconduct Investigations

Agencies sometimes attempt to collect medical information as leverage in disciplinary actions.

This is almost always improper unless:

  • You raise medical issues as a defense (e.g., requesting accommodation)

  • You voluntarily provide medical context

Otherwise, medical information should not be part of:

  • PIPs

  • Misconduct inquiries

  • AWOL cases

  • Conduct unbecoming cases

If performance issues stem from medical limitations, the focus should shift to accommodation, not discipline.

What Agencies Often Ask For (Improperly)

Be cautious if your agency requests:

  • “Everything your doctor has”

  • “All medical records from the last year”

  • “Any documents related to your diagnosis”

  • “All therapy or psychiatric notes”

  • “A list of your medications”

  • “A blanket release form to contact your providers”

These requests violate the Rehabilitation Act, GINA, and multiple federal privacy rules.

How to Protect Yourself

Here are the safest, most effective strategies:

Ask for Specificity

Please identify the specific information needed, why it is necessary, and how it relates to my essential job functions.

This forces the agency to commit to lawful boundaries.

Provide Functional Information Only

Describe how symptoms affect work — not the medical background.

Decline Blanket Releases

Never authorize unlimited access to medical providers unless legally required.

Request Confirmation of Confidential Storage

Your medical information should never be placed in your OPF.

Document Everything

If the agency crosses a line, documentation becomes critical.

Hypotheticals

Hypo 1: The Diagnosis Demand

HR claims they cannot approve a telework accommodation without your diagnosis.
Employee provides functional limitations instead.
Accommodation granted.

Hypo 2: The Overbroad Sick Leave Request

Supervisor demands “full records” for three days of sick leave.
Employee cites policy and provides a short certification.
Request withdrawn.

Hypo 3: The OPF Violation

HR stores medical information improperly.
Employee challenges.
Agency removes it and revises procedures.

When to Get a Lawyer Involved

You should consult a lawyer if:

  • The agency keeps asking for more medical information

  • You feel pressured to disclose private medical history

  • Your medical info was placed in your OPF

  • HR threatens discipline related to medical issues

  • An FFD exam appears retaliatory or unsupported

  • Your accommodation request is stalled or denied

Early intervention prevents bigger problems later.
