I'll try BUT ... have you an appointed Advocate helping you this process ?
If not , strongly recommend you do consider one and / or seek specialist help.
It appears you are at this stage ... Multidisciplinary Team Assessment:
Decision Support Tool – multidisciplinary team assessment
Getting through a Checklist assessment doesn’t mean that your relative qualifies for NHS Continuing Healthcare funding. Instead, it means they go on to stage two of the process, which is the full assessment. A Decision Support Tool (DST) is completed as part of this stage. Remember that this is a supporting document, and the members of the multidisciplinary assessment team (MDT) do not have the power to make the actual funding decision; instead, they make a recommendation, and this is passed to a decision-making panel for the final decision. Have a look at paragraph 31 on pages 14-15 of the DST for the ‘scores’ your relative ideally needs to achieve, and look at page 21 onwards for information on how the assessment is scored and the kinds of things that are assessed.
Be sure, also, to read the section about ‘nature, intensity, complexity and unpredictability’ on page 49; note also: the words ‘single condition’ under Complexity; the words ‘in combination or alone’ in the short paragraph tha follows the bullet points; and the words ‘expected to change’ in the last but one paragraph.
As for a way forward , I cannot see any other alternative except for an Advocate and / or legal advice.
An Internet search ... CHC ADVOCATES ... then narrow down by area.
CHC is NOT a task I would take on myself without specialist help.
Closest analogy ?
Taking on a law case , you as the plantiff , without a supporting barrister.
CHC should NOT be this way but ... in practice , it is !
Others may be able to point you in the right direction ... but without specialist help ?
