R74.01 – Elevation of levels of liver transaminase levels

R74.01 Diagnosis Code: Elevation of levels of liver transaminase levels

• R74.01 is a billable ICD-10-CM code used for reimbursement for the diagnosis of elevation of levels of liver transaminase levels. 
• This ICD-10-CM code is used to diagnose the elevation of levels of liver transaminase levels in America. Internationally, this code may differ.  
• The code is valid until the end of the fiscal year of 2023. 
• This code’s umbrella category is “Symptoms, signs, and abnormal clinical and laboratory findings, not elsewhere classified” under “Abnormal findings on examination of blood, without diagnosis.”
• R74.01 is only used when there’s unknown or unavailable clinical information. 
• It’s recommended that this code not be used as a principal diagnosis unless necessary as it is not definitive.

Is R74.01 Billable?

Yes, R74.01 is billable for insurance reimbursement purposes. 

Clinical Information

• Elevated liver transaminase levels mean that the patient has high levels of liver enzymes, namely alanine transaminase (ALT) and aspartate transaminase (AST), due to an injured or inflamed liver.
• There are many causes of elevated ALT and AST levels. Among them are certain medications, metabolic syndrome, thyroid disorder, hepatitis, metabolic syndrome, and diseases like celiac, Wilson’s, alcoholic liver, and nonalcoholic fatty liver. Aside from having these conditions, those who are at risk of having elevated levels are those with a personal or family history of liver disease, those taking certain medications, those with a history of alcohol abuse, and those who are exposed to hepatitis. 
• Those with mild elevations don’t usually have symptoms and may be among the people whose liver state may be temporary. But those with severe elevations may exhibit symptoms like jaundice, fatigue, nausea, vomiting, diarrhea, abdominal pain, and changes in urine/stool color. 
• In order to assess whether a patient has elevated levels, various diagnostic methods may be employed. These can include conducting blood tests over a specific duration, as well as requesting additional medical procedures such as ultrasounds, CT scans, MRIs, transient elastography, further blood tests, or even a liver biopsy.
• Treatment will vary depending on the cause of the elevated levels.

Synonyms Include:

• ALT level raised
• Aspartate aminotransferase serum level raised
• Aspartate transminase level
• Increased aspartate transaminase level 
• AST/SGOT level abnormal 

Other ICD-10 Codes Commonly Used for Abnormal Enzyme Levels

• R74: Abnormal serum enzyme levels
• R74.8: Abnormal levels of other serum enzymes
• R83.0: Abnormal level of enzymes in cerebrospinal fluid
• R89.0: Abnormal level of enzymes in specimens from other organs, systems, and tissues
