Pre-Employment Medical Exam Laws in Massachusetts

Last reviewed: September 2026

Quick Answer

Under federal law (Americans with Disabilities Act, 42 U.S.C. § 12111) and Massachusetts law (M.G.L. c. 149, § 24L), employers cannot require medical exams before making a conditional job offer. After a conditional offer, exams are permitted only if job-related and required of all applicants for the same position. All medical information must be kept confidential in separate files. Employers cannot withdraw offers based on medical findings unless the condition prevents essential job functions and no reasonable accommodation exists.

Key Facts

  • Massachusetts employers cannot require medical exams before a conditional job offer under ADA rules.
  • Post-offer, pre-employment medical exams must be job-related and consistent with business necessity.
  • All applicants for the same job must receive identical medical examinations under Massachusetts law.
  • Medical information must be kept confidential in separate files under M.G.L. c. 149, § 24L.
  • Employers cannot withdraw offers based on disability unless the exam reveals a legitimate job-related concern.

Federal Law: The Baseline

The Americans with Disabilities Act (ADA), 42 U.S.C. § 12111, establishes the federal framework governing pre-employment medical examinations. Under the ADA, covered employers with 15 or more employees cannot require medical exams or make disability-related inquiries before making a conditional job offer to a job applicant. This applies to any test or procedure that seeks information about an individual's physical or mental impairments or health status.

Once a conditional offer is made, employers may require medical exams, but only if: (1) all entering employees in the same job category are required to undergo the same examination; (2) the information is kept confidential and stored separately from personnel files; and (3) the exam is job-related and consistent with business necessity. The employer cannot withdraw the offer based on medical findings unless the applicant cannot perform the essential functions of the job, even with reasonable accommodation.

The EEOC enforces the ADA pre-employment examination rules. Violations can result in damages for lost wages, emotional distress, and attorney's fees. The exam must be truly conditional—meaning the applicant has already received a contingent offer of employment based on non-medical criteria.

Massachusetts Law: What's Different

Massachusetts law provides stronger protections than federal law in several respects. M.G.L. c. 149, § 24L is the Massachusetts employee medical record privacy law that applies to all medical information, including pre-employment examinations. Unlike the ADA, which applies only to employers with 15 or more employees, Massachusetts law applies to employers of all sizes with one or more employee.

Massachusetts law requires that any medical examination conducted by an employer—whether pre-employment or otherwise—must be kept in a separate, confidential file, apart from the employee's personnel record. Access is strictly limited to occupational health professionals and managers who have a legitimate need to know. Employers cannot disclose medical information without written consent, except in narrow circumstances such as workers' compensation claims or legal proceedings.

M.G.L. c. 149, § 24M further prohibits employers from requiring or requesting any genetic information, genetic testing, or family medical history. This includes genetic tests, carrier status for genetic conditions, and predictive genetic information. Violations carry statutory damages.

While Massachusetts follows the ADA framework of prohibiting pre-offer exams, state courts and the Massachusetts Commission Against Discrimination (MCAD) enforce stricter standards for job-relatedness and business necessity. Massachusetts also requires that if an exam reveals a medical condition, the employer must engage in the interactive process to consider reasonable accommodations before making any adverse employment decision. Remedies under state law include damages for emotional distress, liquidated damages for violations of the genetic testing statute, and attorney's fees.

Key Numbers & Thresholds

No employer size threshold under Massachusetts law (applies to all employers with 1+ employee, unlike ADA's 15-employee threshold). Medical exams permitted only after conditional job offer made. If exam is required, must be administered to all applicants for the same job category without exception. Medical information must be segregated and kept confidential. No statute of limitations specified in M.G.L. c. 149, § 24L; federal ADA charge must be filed with EEOC within 300 days in Massachusetts (deferral state). State claim before MCAD has no fixed deadline but should be filed promptly.

Exceptions & Special Cases

Massachusetts law contains limited exceptions to pre-employment medical exam restrictions. An employer may require medical exams or health-related inquiries if the exam is required by law—for example, Department of Transportation physicals for commercial drivers, or certain fitness-for-duty exams mandated by federal statute. Occupational safety-related inquiries (e.g., asking if a candidate can lift 50 pounds when the job requires it) are permissible before offer if job-related; these are not considered "medical examinations."

The genetic information prohibition (M.G.L. c. 149, § 24M) has narrow statutory exceptions: family medical history obtained incidentally during a medical exam is permissible if not solicited, and genetic information obtained in connection with monitoring or testing for workplace hazards (e.g., lead exposure) is allowed if required by law.

Under the ADA, an employer may ask about ability to perform specific job functions before an offer is made (e.g., "Can you stand for 8 hours?"), but cannot ask whether the applicant has a disability or medical condition. The distinction between permissible functional questions and impermissible medical inquiries is critical and fact-dependent.

Small employers (under 15 employees) are not covered by the ADA but remain subject to Massachusetts state law requirements. Union collective bargaining agreements may contain provisions regarding medical exams, though these must still comply with state and federal anti-discrimination law. Medical exams required as part of background checks or security clearance processes (e.g., for government contracts) may have additional regulatory exceptions, though Massachusetts law still applies.

What to Do If Your Rights Are Violated

Step 1: Document the violation thoroughly. Keep copies of any medical questionnaires, exam forms, or requests for medical information provided before your conditional job offer. Record dates, times, and names of individuals who requested medical information. Retain any communications (email, letters, phone notes) from the employer mentioning medical exams, health questions, or disability-related inquiries prior to offer. Take screenshots of online application portals if they contained prohibited medical questions. Note whether other applicants for the same position were treated differently.

Step 2: Determine if an internal complaint process exists. Review the employer's employee handbook or hiring materials for a complaint procedure; however, for pre-employment violations, there may be no internal mechanism since you are not yet hired. You may contact the hiring manager or HR in writing (email preferred for documentation) to formally object to the medical exam requirement and request clarification of the business necessity for the exam. Send this via email to create a written record. Do not delay formal agency filing while pursuing internal resolution.

Step 3: File a charge with the appropriate agency. If the employer has 15 or more employees, file a charge with the Equal Employment Opportunity Commission (EEOC) at www.eeoc.gov or visit the Boston Area EEOC office (JFK Federal Building, 15 New Sudbury Street, Boston, MA 02203; phone: 1-617-565-3200). You have 300 days from the violation to file (Massachusetts is a deferral state). Alternatively, or in addition, file a complaint with the Massachusetts Commission Against Discrimination (MCAD) at www.mass.gov/mcad; phone: 1-617-994-6000. MCAD accepts complaints from applicants and can investigate violations of state medical privacy law (M.G.L. c. 149, § 24L and § 24M) regardless of employer size. Provide specific dates, the text of medical questions asked, names of individuals involved, and confirmation of whether you were made a conditional offer prior to the exam requirement.

Step 4: Understand the investigation process. The EEOC will issue a "receipt of charge" and conduct an investigation, typically taking 2-6 months. EEOC will contact the employer for a response and may interview you and witnesses. The agency will determine whether probable cause exists to believe discrimination occurred. If probable cause is found, EEOC will attempt conciliation. If conciliation fails, you may receive a "right to sue" letter, which permits you to file a federal lawsuit in U.S. District Court. MCAD investigations typically take 4-8 months and follow similar procedures; MCAD can issue a determination and, if violations are found, seek remedies on your behalf.

Step 5: Consult an employment law attorney. Contact an employment discrimination attorney licensed in Massachusetts before filing if possible; if not possible, file the charge and consult an attorney immediately after. An attorney can review the facts, assess whether a viable ADA or state law claim exists, advise on negotiation or settlement, and represent you in investigation proceedings or litigation if necessary. Many employment lawyers work on contingency for discrimination cases. Legal aid organizations in Massachusetts can provide referrals if cost is a barrier.

Frequently Asked Questions

Can an employer ask about my medical history or disabilities on the job application or during the interview before making an offer?

No. Under the ADA (42 U.S.C. § 12111) and Massachusetts law (M.G.L. c. 149, § 24L), employers cannot ask disability-related questions or require medical exams before making a conditional job offer. This includes questions about mental or physical health conditions, past medical treatment, medications, or disabilities. Employers also cannot ask about family medical history under M.G.L. c. 149, § 24M (the genetic testing law). However, employers can ask job-specific functional questions: "Can you lift 50 pounds?" or "Can you work outdoors in various weather?" These are permissible because they ask about job function, not medical status. If you are asked prohibited medical questions before an offer, this is a violation regardless of whether you are hired.

What counts as a 'conditional job offer' in Massachusetts?

A conditional job offer is an offer of employment that is conditioned only on the results of a post-offer background check, reference verification, or other permissible screening—not on medical findings. In Massachusetts, the offer must be genuine and made in writing or clearly communicated. Once you receive a conditional offer, the employer can then require medical exams. However, the offer must have been made based on non-medical criteria. An ambiguous statement like "we'd like to move forward pending a few things" may or may not constitute a conditional offer; courts look at the totality of circumstances. If you believe you were subjected to a medical exam before receiving a clear conditional offer, document the timeline of communications and consult an attorney.

Can an employer withdraw a job offer after I complete a required post-offer medical exam?

An employer can withdraw a conditional offer based on medical exam results only if the employer can demonstrate that: (1) the medical condition prevents the applicant from performing an essential function of the job; (2) the condition poses a direct threat to health or safety; and (3) no reasonable accommodation could enable the applicant to perform the job safely. Massachusetts courts and the MCAD enforce a high bar for this defense. The employer must have a legitimate, job-related reason documented before the exam. The employer cannot withdraw the offer simply because the applicant has a disability, or because accommodating the disability would be inconvenient. If you believe an offer was wrongfully withdrawn, contact an employment attorney immediately; you may have claims under the ADA and state disability discrimination law.

Do all applicants for the same job have to take the same medical exam in Massachusetts?

Yes. Under the ADA and Massachusetts law, if an employer requires a post-offer medical exam, it must administer the identical exam to all applicants for the same job position. The employer cannot require more extensive exams for certain applicants based on disability status, age, race, or other protected characteristics. If you discover that you were asked to undergo a more invasive or comprehensive medical exam than other applicants for the same role, this is evidence of discrimination. Similarly, if some applicants were not required to take an exam while you were, this raises a violation. Document any disparity in exam requirements and report it to the MCAD or EEOC.

What happens to my medical information after an employer conducts a post-offer medical exam?

Under M.G.L. c. 149, § 24L, all medical information obtained by an employer—including pre-employment or post-offer exams—must be kept strictly confidential and stored in a separate medical file, apart from your personnel record. Access is limited to occupational health professionals and managers with a legitimate need to know. Employers cannot disclose medical information to coworkers, the general public, or other departments without your written consent. Violations can result in civil damages. If you discover your medical information has been disclosed inappropriately or commingled with your personnel file, report the violation to MCAD. Additionally, if you believe the employer is using medical information improperly (e.g., to discriminate against you or deny advancement), this may constitute both a privacy violation and a discrimination claim under state law.
