LouLou,
From what I am told by the CFF is the CFF is in the process of a new ICD9 code for Atypical CF and CF like illness that lack known disease causing mutations, and that process is a long one. Some cases that are considered Atypical CF do fall into the CFTR Related Metabolic Syndrome category to date, but a lot of cases don't. My kids are referred to as Atypical CF but are coded as CF. The way the dr. that diagnosed my kids with Atypical CF describes it as:
This means that although they do not meet the diagnostic criteria for a classic cystic fibrosis diagnosis, their symptoms match those of classic CF patients. Cystic fibrosis is a genetic disease in which a person inherits two mutated copies of the CF gene. This change in the gene leads to the symptoms of CF. In my children, the mutations in the CF gene are thought to be not as severe as those of classic CF patients. However, there is something in their genetic makeup which, in combination with their CF mutations, has led them to manifest these same symptoms.
Hopkins does recognize and diagnose patients with Atypical CF but I believe code them as CF for now. There are several other CFF accredited centers that recognize Atypical CF but unfortunately there are a lot that have not yet been educated. The education process is a long and continuing process.
