Whether you are looking into treatment for yourself or for someone in your life, our team can confirm your cover and clarify what the next step looks like from there.

What is United Healthcare Global?

United Healthcare Global is an international health insurance product. It’s separate from the standard UHC plans issued in the United States.

UHC Global is designed for people living and working outside their home country. If you’re an expat, an internationally mobile professional, or someone whose employer provides international cover, your policy is likely a UHC Global plan.

What can United Healthcare Global cover at Castle Craig?

  • Medically supervised detox

    Detox is the first stage of residential treatment. At Castle Craig, withdrawal is medically managed by our clinical team. UHC Global policies often cover the detox stage as part of an approved treatment plan.

  • Residential addiction treatment

    Residential treatment means living on site for the duration of the programme, with a structured daily timetable of therapy, group work, and 12 Step facilitation. UHC Global policies typically provide this level of addiction rehab insurance cover.

  • Therapy, mental health, and dual diagnosis

    Castle Craig’s programme includes Cognitive Behavioural Therapy (CBT), one-to-one counselling, and group therapy. If you have a mental health condition alongside addiction, we assess and treat both within the same programme. UHC Global cover for therapy and dual diagnosis is common.

How to use your United Healthcare Global insurance for rehab at Castle Craig

  • Check your policy

    Contact UHC Global to confirm what your plan covers. If your policy requires pre-authorisation for residential treatment, this is where that happens. Pre-authorisation means your insurer agrees the treatment is medically necessary before it starts. Our team knows what UHC Global usually asks to see, so if you’re not sure where to start, we can advise you. 

  • Call Castle Craig with your policy details

    Once you know what your cover includes, call us. It helps to have your membership number, the policyholder’s name, and your plan documents to hand. Those details let us start the insurance checks straight away. Our team will explain how your policy applies to our programme and answer any questions about treatment.

  • We liaise with UHC Global on your behalf

    Castle Craig’s admissions team manages the insurance process directly with UHC Global. We handle the paperwork, chase authorisations, and keep you informed at every stage, so you don’t have to coordinate between us and your insurer.

    If you’re calling on behalf of someone in your life, the conversation works the same way.

    Contact us with your UHC Global policy details and we’ll take it from there.

What does United Healthcare Global give you access to at Castle Craig?

Castle Craig is a residential treatment centre in the Scottish Borders, set in 50 acres of private countryside near Edinburgh. The programme is led by a Consultant Psychiatrist and delivered by a multidisciplinary clinical team.

What if your United Healthcare Global policy doesn’t fully cover treatment?

If your UHC Global policy covers part of the cost, you can make up the difference through self-pay. Castle Craig offers flexible payment options, and our admissions team will help you understand your cover before you commit to anything. We’ll set out clearly what your policy pays and what the difference would be, so you’re not caught out partway through treatment.

It’s a conversation we have regularly, and we can help you work out the best route. Learn more about insurance for addiction rehab at Castle Craig.

Frequently asked questions about United Healthcare Global and rehab

  • Is UHC Global the same as UnitedHealthcare?

    They’re related but different products. UnitedHealthcare is a US domestic health insurer. UHC Global is the international arm, designed for people living and working outside the US. If you’re based in the UK with an employer-provided international plan, yours is most likely UHC Global.

  • Do I need a GP referral to use United Healthcare Global for addiction rehab?

    That depends on your plan. Some UHC Global policies require a GP referral or pre-authorisation before residential treatment can begin. Castle Craig’s admissions team can help you check this and guide you through whatever your policy needs.

  • How long does pre-authorisation usually take with UHC Global?

    Timelines vary depending on the policy and the information UHC Global needs. Castle Craig’s admissions team has experience managing this process and can help move things along. If you call us with your policy details, we can give you a better idea of what to expect.

  • Can United Healthcare Global cover continuing care after residential rehab?

    Some UHC Global policies include cover for aftercare and continuing support following residential treatment. It’s a question we’d recommend asking your insurer, or you can ask Castle Craig’s admissions team to check on your behalf.

  • Can a family member use their UHC Global policy to fund treatment for someone in their life?

    In some cases, yes. Whether a family member’s policy can cover treatment for someone else depends on the terms of the plan and how it defines dependants. The simplest way to find out is to call our admissions team with the policy details, and we’ll help you work it out.
