ex-tenant's guest asking for my insurance to file a fall claim

[Nancy Wang]

Tenant has moved out 30 days ago. Today received a text message from a lady saying she had a fall in my property when it was rented to that tenant. Tenant's insurance has assisted her. Now she is still not well and need medical care. She wanted me to provide her my insurance info so she can make a claim. 

What should I do? Shall I give her my insurance info, and contact my insurance provider? or ignore this text message waiting for further formal request? 

Tenant has moved out for 30 days. I was never aware of this fall. My house is in a good neighborhood and in good condition built in 2005. 

Thank you for your insights/expertise/suggestions!
