Understanding how specialist referrals, diagnostic investigations, and legal rights work within the NHS in England gives you far more control over your care and waiting times. Healthwatch Cambridgeshire
Below is an overview of how referrals progress, the key waiting standards, your legal entitlements under the NHS Choice Framework, and a practical checklist to help you manage your referral. Sample Page
1. Specialist Referral Pathways
When a GP, dentist, or optometrist determines that you require care beyond primary medical services, they initiate a specialist referral.

Referral Types
- Routine Elective Referrals: Managed via the NHS e-Referral Service (e-RS). You should be offered a selection of suitable providers (often up to 5 options) based on location, waiting times, and quality ratings.
- Urgent Suspected Cancer Referrals: Initiated when specific red-flag symptoms are present. Under the 28-day Faster Diagnosis Standard, you must receive a definitive diagnosis or have cancer ruled out within 28 days of GP referral.
- Self-Referrals: For certain community-based NHS services—such as NHS Talking Therapies (IAPT), podiatry, and sexual health—you can refer yourself directly without going through a GP.
2. Diagnostic Tests & NHS Standards
Diagnostic tests (such as MRI scans, CT scans, endoscopies, and cardiac investigations) form a crucial bridge between your initial consultation and the final treatment plan.
| Pathway / Indicator | Standard Target | Details |
| Referral to Treatment (RTT) | 18 Weeks | Maximum wait for non-urgent elective care, from referral to start of treatment. |
| Diagnostic Test Wait | 6 Weeks | Maximum wait target for key diagnostic tests and imaging. |
| Faster Diagnosis Standard | 28 Days | Target for urgent suspected cancer diagnosis or ruling out cancer. |
| First Cancer Treatment | 31 Days | Maximum wait from decision to treat to actual commencement of treatment. |
3. Your Patient Rights & “Right to Choose”
Under the NHS Constitution and the NHS Choice Framework, you hold specific legal rights regarding where and how you receive elective care:
Key Legal Entitlements
- Choice of Hospital & Clinical Team: If you need an elective specialist referral, you have the right to choose any hospital or clinic in England that is commissioned by the NHS for that service.
- Independent / Private Providers: Under Right to Choose (RTC), you can select an independent (private) provider—such as for adult ADHD/Autism assessments or orthopaedics—as long as they hold an NHS contract for that specific service. Care remains 100% NHS-funded.
- 18-Week Breach Options: If your local provider cannot offer an appointment within 18 weeks (and no exceptional clinical delay applies), the local Integrated Care Board (ICB) must take reasonable steps to offer you a suitable alternative provider with a shorter queue.
Where Right to Choose Does Not Apply
- Urgent / Emergency care and emergency admissions.
- Cancer services requiring immediate speed of access.
- Services commissioned solely by local authorities (e.g., public health drug and alcohol services).
- Self-referred care (you must have a valid referral from a GP, dentist, or optometrist).
