How to explain rehab to your employer

Published October 25, 2024 · 7 min read · Updated April 2026

You do not owe your employer a detailed explanation. FMLA and HIPAA provide protections that allow you to take medical leave without disclosing your diagnosis.

What you must disclose

For FMLA: your healthcare provider certifies medical necessity on a form that does NOT require specifying the diagnosis. You request medical leave.

What you can say

I need medical leave for a health condition. My doctor has provided the medical certification. I expect to return on approximately this date. That is enough.

What you should NOT say

You are not required to say addiction, rehab, drug, or alcohol. HR is not entitled to your diagnosis. Your medical records are HIPAA-protected.

If you choose to disclose

Some people find that honesty with a supportive employer strengthens the relationship. Consider the workplace culture. If you disclose, the ADA protects you from discrimination based on recovery status.

After returning

Focus on performance. Do not overshare with colleagues. Use EAP for ongoing support. Attend outpatient treatment on your own time or use FMLA intermittent leave.
