Results out of range??

My mother has been with Momentum for many years and in general, they have been really amazing. She had open heart surgery 8 years ago and we had nothing to worry about as far as Momentum was concerned as they covered all the expenses. In general, Mom has been happy with Momentum, until now. She has recently suffered a mild stroke which has affected her vision and currently in Hospital. Upon getting her medical aid approved at the hospital, authorization was given and we were assured we had nothing to worry about , until we started getting call for co payments. We had to fork out 2 co payments at R1800 each to cover scans that were done as Momentum do not provide gap cover for their clients. My Mothers installments each month for herself are over R2200 per month. No other beneficiaries. Now she has received an sms from Momentum saying the following. We have received your health assessment and some of the results are out of range. Please see email to follow advising next steps.

Help pls!
