Office of Accountability & Whistleblower Protection, Training - Exposure - Experience (TEE) Tournament, War Related Illness & Injury Study Center, Clinical Trainees (Academic Affiliations). Once fibrosis is extensive, cirrhosis installs and depending on stage, can also lead to liver failure. **Note 1:** Physician statement of fibrosis score can be used to code this data item when no other information is available. While originally developed to detect liver fibrosis among patients with Hepatitis C and HIV, FIB-4 scoring has been increasingly used by the diabetes and NAFLD/NASH communities.

Ishak classification for stage of disease with modification to a 4 Importantly, the absence of these findings does not rule out cirrhosis or advanced fibrosis. Developing cirrhosis Commonly used scoring systems are the Knodell score/Histological Activity Index (HAI), the METAVIR score, and the Ishak score (modified Knodell score). However, research into antifibrotic drugs, which will reduce or prevent the fibrotic process, is ongoing. Intraobserver and interobserver variations in liver biopsy interpretation in patients with chronic hepatitis C. Hepatology 1994; 29:15. For example, research has preliminarily shown the type 2 diabetes medication pioglitazone to improve NASH in people who do not have diabetes. The medical record may show something like "FIB-4 = 3.52." Do not code FIB-4 values in this data item. The good thing with this scoring system is that it makes use of readily available data. Medical News Today has strict sourcing guidelines and draws only from peer-reviewed studies, academic research institutions, and medical journals and associations. Cirrhosis was defined as fibrosis with an Ishak score of 5 or 6. The test is performed by using a piston that is used to lightly push the skin over an intercostal space, resulting in a shear wave that travels through the liver. There are four criteria to be followed in the model as explained below: Age There is a correlation between age increase and the progression of fibrosis in the liver, especially in the case of hepatitis C and chronic alcohol consumption but the biological mechanism behind is yet to be established.
