How do I get a written cost estimate from an Indian hospital?

Email your recent reports to the hospital's international patient desk and ask for a treatment plan and estimate. The estimate should be on hospital letterhead and list the procedure, expected stay, room category and inclusions. Ask how long the estimate is valid. If you use a facilitator, ask them to share the hospital's original document, not a retyped version. Mention the room category you prefer, since that changes the figure, and ask what could push the cost higher.
