When your liver is damaged or inflamed, it can release ALT into your bloodstream. This causes your ALT levels to rise. A high ALT level can indicate a liver problem, which is why doctors often use an ALT test when diagnosing liver conditions.
Specifically, a slight elevation to AST and ALT. For example, on a routine Comprehensive Metabolic Panel (CMP), a woman will have an AST level of 54 U/L and an ALT level of 47 U/L.
Risk factors for liver disease include:
ICD-10 code: R94. 5 Abnormal results of liver function studies.
R94. 5 - Abnormal results of liver function studies | ICD-10-CM.
R74.0ICD-10-CM Code for Nonspecific elevation of levels of transaminase and lactic acid dehydrogenase [LDH] R74. 0.
R74. 8 - Abnormal levels of other serum enzymes. ICD-10-CM.
An ALT test measures the amount of ALT in the blood. High levels of ALT in the blood can indicate a liver problem, even before you have signs of liver disease, such as jaundice, a condition that causes your skin and eyes to turn yellow. An ALT blood test may be helpful in early detection of liver disease.
821. Revised descriptor for ICD-10-CM diagnosis code Z77. 29.
Transaminitis, or hypertransaminasemia, refers to unusually high levels of a family of enzymes called transaminases. Transaminitis is not a disease, but it can point to other issues that require treatment. High levels of fat or similar problems may be causing inflammation in the liver.
ALT is an enzyme found in the liver that helps convert proteins into energy for the liver cells. When the liver is damaged, ALT is released into the bloodstream and levels increase. Aspartate transaminase (AST). AST is an enzyme that helps metabolize amino acids.

Elevated liver enzymes might be discovered during routine blood testing. In most cases, liver enzyme levels are only mildly and temporarily elevated. Most of the time, elevated liver enzymes don't signal a chronic, serious liver problem.
The 2022 edition of ICD-10-CM R74.0 became effective on October 1, 2021.
R74.0 should not be used for reimbursement purposes as there are multiple codes below it that contain a greater level of detail.
