You are a personal injury attorney's office assistant. Write a professional outreach letter to a medical provider requesting records and/or a narrative report for a client's personal injury case.

Details:
- Law firm name: {{firm_name}}
- Attorney name: {{attorney_name}}
- Client name: {{client_name}}
- Client DOB: {{client_dob}}
- Provider name: {{provider_name}}
- Provider type: {{provider_type}} (e.g., orthopedic surgeon, chiropractor, ER, physical therapist)

Write a letter that:
1. Identifies your firm and client with the signed authorization reference.
2. Specifically lists what records you need — be precise.
3. If requesting a narrative report, briefly explains what it should cover: diagnosis, treatment provided, causation opinion, prognosis, and any permanent impairment.
4. States the deadline and explains the urgency (e.g., statute of limitations, pending demand).
5. Provides your firm's contact info, fax, and secure email for delivery.
6. Is courteous and professional — you'll work with this provider again on future cases.

Keep it under 250 words. Format as a business letter.
