What to ask before you call
Methadone is a daily-dose program. That changes the questions you should be asking. Run through these before you commit to a clinic:
- What time does dosing start, and what time does it close? Daily methadone often means a 6am window five or six days a week.
- Which insurance plans do you bill? Medicaid coverage for OTPs varies by state plan and managed-care organization.
- How long does intake take from first call to first dose? In some states it is same-day. In others it can run a week.
- What is your take-home schedule? Federal rules let stable patients earn take-home doses over time. Clinic policy on how fast you earn them differs.
- Do you offer counseling on-site or do I coordinate it elsewhere?
