From 93 years ago, thanks to Aunt Edie Fischer, we have a copy of Grandma Lydia Domsch Ziegelbein's hospital bill. In November of 1919, she had an appendectomy at the hospital in Kensington, Kansas.
Note that she was in the hospital for 13 days (!) and at $25 per week for the room. The special nurse was at the same rate, while the operating room and anesthetic were each $10.
Times have changed for sure, and we're all grateful for the successful operation, or we wouldn't be reading about it!
