Can Your Employer Ask Your Diagnosis When You Request an ADA Accommodation?

The short answer: your employer can request documentation that establishes you have a qualifying impairment and need the accommodation you are requesting. They generally cannot demand your specific diagnosis label, your full medical records, or detailed treatment history. This guide walks through what HR can legally ask, what they cannot, and how to protect your privacy through the process.

What the EEOC actually says

The Equal Employment Opportunity Commission enforces the ADA in employment cases. The EEOC's enforcement guidance on reasonable accommodation is the controlling federal document on this question.

The EEOC's position is straightforward. When the disability or need for accommodation is not obvious, the employer may ask for "reasonable documentation" that establishes:

1. The existence of a covered impairment

2. The functional limitations the impairment causes

3. The accommodation that would address those limitations

The EEOC also says explicitly that the employer is not entitled to your complete medical records, is not entitled to require you to use the company's preferred provider, and is not entitled to extensive medical history beyond what is needed to evaluate the specific accommodation request.

In other words, HR can verify that you have something that qualifies. They cannot run a full clinical investigation of your life.

What "reasonable documentation" usually includes

A standard ADA accommodation letter from a qualified provider typically includes:

• A statement that the patient has a qualifying mental or psychological condition under the ADA

• A description of the functional limitations the condition produces

• A specific accommodation request and the clinical reason it would address those limitations

• The provider's credentials and license information

• A signature and date

Notice what is not typically included: the specific DSM-5 diagnostic code, treatment history, medication history, family history, prior providers, or session notes. None of those are required for the documentation to be ADA-sufficient.

A letter that establishes "patient meets criteria for a qualifying mental health condition and demonstrates substantial limitations in [specific major life activities] that would be addressed by [specific accommodation]" is generally enough. The provider can choose to include the diagnostic label, but is not required to.

Where HR sometimes oversteps

In practice, some HR departments ask for more than they are entitled to. Common overreaches:

• "We need to see your full medical records." They do not.

• "You must use our employer-approved provider." They cannot require this.

• "Tell us your specific diagnosis." They can ask, but you can decline to provide a specific label as long as your documentation establishes the qualifying impairment.

• "We need detailed treatment history." This is generally beyond what the EEOC requires.

• "We will only accept documentation from a medical doctor." Per EEOC guidance for mental health providers, this is incorrect. Psychologists, LCSWs, LPCs, NPs, occupational therapists, and other qualified providers are explicitly recognized as appropriate documentation sources.

If your HR department is asking for things outside the EEOC framework, you do not have to comply. You can ask them to specify what specifically they need to evaluate your accommodation request and have your provider respond to that, rather than handing over a full medical file.

What HR can legitimately follow up on

The interactive process is a back-and-forth. After receiving your initial documentation, HR may legitimately ask follow-up questions, including:

• Clarification on whether the limitations are permanent, episodic, or expected to resolve

• Whether alternative accommodations would also address the limitations

• The provider's basis for the assessment (clinical observation, validated screening tools, etc.)

• How the requested accommodation specifically addresses the documented limitations

Your provider can respond to these questions in writing, but only with your written authorization. You retain control over what information leaves your provider's office.

We cover the interactive process more broadly in what happens after your employer receives your accommodation letter. Washington University in St. Louis also maintains a public-interest summary on what happens after you submit a request that walks through the standard back-and-forth.

Confidentiality protections under the ADA

The ADA requires employers to keep medical information about employees confidential, separate from regular personnel files. This includes:

• Documentation submitted as part of accommodation requests

• Medical information disclosed during the interactive process

• Information about leave related to medical conditions

Access should be limited to people with a legitimate need to know (typically the HR contact and the supervisor who needs to implement the accommodation). Your coworkers do not have the right to know why you have an accommodation. Your manager does not have the right to know your specific diagnosis to implement schedule changes or remote work.

If you believe your medical information has been inappropriately shared, that itself may be an ADA violation separate from the accommodation question.

What you can disclose vs. what you must disclose

Disclosure to your direct manager and disclosure to HR are different things.

You generally do not have to disclose your specific diagnosis or any medical details to your manager. The interactive process is typically routed through HR, and your manager may simply be told that you have an approved accommodation that requires (for example) remote work three days per week. They do not need to know why.

This is one of the most underappreciated parts of the ADA framework. Many employees assume they will have to have a personal conversation with their boss about their mental health condition. In most well-functioning HR processes, you do not.

What if your employer demands your specific diagnosis?

If your employer insists on knowing your specific diagnosis label and is treating that as a condition of granting your accommodation, you have a few options:

1. Push back with your provider's help. Ask your provider to issue a follow-up letter clarifying that the documentation already establishes the qualifying impairment and that the specific diagnostic label is not required under EEOC guidance.

2. Reference the EEOC documentation standard directly. A short note to HR pointing to the EEOC enforcement guidance and asking what specifically about the existing documentation is insufficient often resolves it.

3. Consult JAN. The Job Accommodation Network is a free federal service that provides confidential consultation on accommodation issues. They can help you frame your response.

4. Consult an attorney. If your employer is using "we need your diagnosis" as a stalling tactic or a way to deny accommodations they would otherwise have to grant, this may rise to an ADA violation. An employment attorney can evaluate the specifics.

How WorkWell handles this

The accommodation letters our partner psychologists issue are structured to satisfy the EEOC documentation standard without including unnecessary clinical detail. The letter establishes the qualifying impairment, describes the functional limitations, specifies the recommended accommodation, and includes the provider's credentials. It does not include session notes, full diagnostic workup, or treatment history.

This is intentional. The letter is designed to give HR exactly what they need to evaluate the request and nothing more. You retain control over what additional information is shared if HR asks follow-up questions.

Bottom line

Your employer can request reasonable documentation that establishes you have a qualifying impairment and need the requested accommodation. They generally cannot demand your specific diagnosis, your full medical records, or detailed treatment history. The EEOC documentation standard is about functional limitations, not clinical labels.

A properly structured accommodation letter from a qualified provider gives HR what they need to make a decision while keeping your medical privacy intact. If HR is asking for more than the EEOC requires, you have legal grounds to push back.
