What an ADA Mental Health Accommodation Letter Should Include

Last updated: 4/22/2026

HR departments reject accommodation letters every day for being too vague, too generic, or missing the elements they actually need. A note that says "patient has anxiety, recommends remote work" is unlikely to get past a thorough HR review. A letter that documents the nature of the condition, the specific functional limitations affecting the patient's work, and ties the recommended accommodation to those limitations stands a much better chance.

This guide gives you the quality bar. Six elements every strong ADA mental health accommodation letter should include, drawn from EEOC enforcement guidance and the EEOC's resource on mental health conditions in the workplace. If you already have a letter, use this to sanity-check it. If you're about to request one, share these criteria with your provider.

This isn't legal advice. Accommodation outcomes depend on your employer's interactive process, not on letter quality alone — but letter quality does the front half of the work. For broader context, our Washington University-hosted resource on workplace accommodations covers the full process.

Why letter quality matters more than people think

HR rejection patterns are predictable. A letter that reads like a sick-day note gets a follow-up request for "more specific information," which delays your accommodation by weeks. A letter that reads like EEOC-aligned documentation goes through.

The role of the letter is to start the interactive process, not to win it. Your employer is required to engage in good-faith dialogue once you've made a documented request. That dialogue can still result in denial, modification, or counter-proposal — see Can My Employer Deny My ADA Accommodation Request? for what's permissible. But a strong letter sets the floor: it establishes that you have a recognized condition, that it has functional impact on your work, and that the requested accommodation is reasonably tied to that impact.

Employers push back on weak documentation because weak documentation is easy to push back on. They generally accept strong documentation because the legal cost of rejecting clinically credible documentation is higher than accepting it.

The six elements every strong letter includes

1. Provider credentials block. What HR looks for: name, degree, state license, license number, areas of specialization. PSYPACT authorization for telehealth providers (verifiable via the PSYPACT Directory).

Strong example: a structured header with credentials clearly visible — "Charles Williams, Ph.D., MSCP / Licensed Clinical Psychologist / [State] License #XXXXX / PSYPACT Authorized Provider."

Weak example: handwritten on a prescription pad with just "Dr. Williams" and a phone number.

For a deeper look at credential matching, see Which Credentials Are Best for an ADA Accommodation Letter?.

2. Established clinical relationship statement. A brief statement that the provider has evaluated the patient.

Strong example: "I conducted a clinical evaluation of [patient] on [date] for the purpose of assessing functional impairments related to a workplace accommodation request."

Weak example: silent on whether the provider has actually evaluated the patient.

3. Description of impairment as a recognized condition. The condition is framed as a clinical disorder, not as workplace stress or a personality trait.

Strong example: "The patient meets DSM-5-TR criteria for [generalized anxiety disorder / major depressive disorder / etc.]." Or, if avoiding diagnosis: "The patient experiences a recognized mental health condition that meets the threshold of a substantial impairment as defined by the ADA."

Weak example: "Patient seems stressed at work."

For why a formal diagnosis isn't strictly required, see Do You Need a Diagnosis to Get an ADA Workplace Accommodation?.

4. Functional limitations — the most important section. What major life activities the condition limits and how, focused on workplace impact. The Job Accommodation Network (a Department of Labor service) maintains comprehensive lists of functional limitations associated with most qualifying conditions, useful as a reference framework.

Strong example: "The patient's symptoms cause functional limitations in concentration and sustained focus, particularly in environments with frequent interruptions or sensory overstimulation. These limitations substantially affect the patient's ability to perform sustained cognitive work and maintain stable focus across a workday."

Weak example: "Patient has trouble concentrating."

5. Recommended accommodation tied to limitations.

Strong example: "A primarily remote work environment with reduced interruption and sensory load would substantially mitigate the functional limitations described above. Recommended for an initial period of 12 months, subject to clinical reassessment."

Weak example: "Patient should work from home."

6. Duration and review timeline.

Strong example: "Recommended for an initial period of 12 months, subject to clinical reassessment."

Weak example: silent on duration.

What to leave out (and why)

Diagnosis codes (ICD-10 or DSM-5) are not required for the employer's interactive process, and including them creates privacy exposure with no upside.

Detailed treatment history is irrelevant to functional impact.

Specific medications and dosages are irrelevant and potentially used by employers to make assumptions.

Sessions notes or therapy content are protected health information and have no place in an accommodation letter.

Emotional language ("patient is suffering," "this is a serious case") should be replaced with clinical, functional language. It reads as more credible to HR.

A strong letter is short, structured, and clinical. A two-page letter that includes everything looks weaker than a one-page letter that includes the right things.

Conditions covered

This category includes anxiety disorders, major depressive disorder, persistent depressive disorder, ADHD, PTSD, obsessive-compulsive disorder, bipolar disorder, eating disorders, panic disorder, social anxiety disorder, and chronic conditions with significant mental health components such as chronic illness with comorbid depression. We have condition-specific guides for anxiety, depression, ADHD, PTSD, and chronic conditions like fibromyalgia and Long COVID.

The condition must be a recognized mental or psychological disorder that substantially limits one or more major life activities. Workplace stress, interpersonal conflict with a manager, or a strong preference for working from home are not protected mental health conditions on their own.

Common HR objections and how a good letter pre-empts them

The "we need more specific information" trap is the most common pushback. A good letter pre-empts this by being specific from the start about functional limitations — not by including more clinical detail. If HR keeps asking for more, you can refer them back to the specific functional language already in the letter. If they keep pushing, our Medium guide on denied requests walks through your escalation options.

The "this isn't a reasonable accommodation" pushback usually comes when the recommended accommodation is broad (e.g., "should work from home") without being tied to the limitations. A letter that ties the accommodation directly to specific functional impacts makes this objection harder to sustain.

The "the provider isn't qualified" challenge usually means the credential type doesn't match the condition. A psychiatrist documenting a back injury invites this. A licensed psychologist documenting anxiety does not.

When employers try to require their own forms instead of accepting your letter, you're generally allowed to provide your own documentation as long as it includes the information their form requests. Their form is a convenience, not a legal requirement under EEOC guidance.

How to verify the writer's credentials

For PSYPACT psychologists, search the PSYPACT Directory. The directory shows which jurisdictions the provider is authorized in.

For non-PSYPACT credentials, look up the state psychology, social work, or counseling licensing board for the state where they're licensed.

What HR will check: license number, status (active vs. expired), and disciplinary history. Make sure your provider's credentials are clean and current before you submit the letter.

PSYPACT-authorized psychologists won't appear in individual state licensing databases — those check single-state licenses. The PSYPACT directory is the source of truth for PSYPACT credentials.

Frequently asked questions

How long should an accommodation letter be?

Typically one to two pages. Longer letters often dilute the key information.

Does my letter need a formal diagnosis?

No. Functional limitations are what the EEOC requires. A diagnosis label alone is not sufficient, and its absence is not disqualifying. See Do You Need a Diagnosis.

Can my therapist write the letter, or does it need to be a psychiatrist?

A licensed mental health professional, including a therapist, can write the letter for mental health conditions if they have the appropriate credentials.

What if my condition isn't formally diagnosed?

A qualified provider can still document a recognized mental health condition based on a clinical evaluation, even without a prior formal diagnosis.

Can the same letter cover multiple accommodations?

Yes. A letter can recommend multiple accommodations such as remote work, schedule flexibility, and reduced sensory load tied to the same set of functional limitations. See ADA Accommodation for Schedule Changes and Hybrid Work.
