Letter to insurer requesting additional services

Write a letter to an insurer requesting additional services or extension of cover for a client.

Insurer: WorkCover / WorkSafe
Client first name + surname: {{client_name}}
Client claim/policy number: {{claim_number}}
My discipline: Physio
What I'm requesting (number of sessions, type of service, extension period): {{request}}
Clinical justification (your raw notes — what's been done, what's needed, why): {{justification}}
Outcome measures or evidence supporting the request: {{evidence}}

Write a formal insurer letter, 280-380 words. Standard structure:
- 'Dear Case Manager / Claims Team' opening
- Reference: claim number + client name
- Brief context (1 paragraph): episode of care to date, sessions delivered, key findings
- Clinical reasoning (1-2 paragraphs): why the additional services are necessary, what risk/cost the insurer avoids by approving
- The specific request (1 paragraph): exactly what I'm asking for + cost if relevant
- Supporting evidence: outcome measure scores, functional improvements, etc.
- Close: 'I'm happy to discuss further. Please don't hesitate to contact me.'

Formal but not stiff. Australian conventions. Use 'I' not 'we' if I'm a sole practitioner.
