Option 1
Appeal the decision
If you believe the Decision Support Tool was scored incorrectly, the Multi-Disciplinary Team weighting was wrong, or the National Framework was not properly applied, you can ask the ICB for a local review. If that fails you can escalate to NHS England's Independent Review Panel.
Appeals work when there is concrete evidence the assessment missed something material. They take time, often six to twelve months. They cost nothing if you handle them yourself, or a few thousand pounds with a specialist solicitor for complex cases.
Free option: Beacon CHC is NHS-funded and offers free independent advice on whether to appeal and how to present the case. Use this before paying anyone.
