What is the ICD 10 diagnosis code for liver function test?

A: The ICD-10-CM index lists code R79. 89 (Other specified abnormal findings of blood chemistry) as the default for abnormal liver function tests (LFTs).

What is the medical term for GGT?

A gamma-glutamyl transferase (GGT) test measures the amount of GGT in the blood. GGT is an enzyme found throughout the body, but it is mostly found in the liver. When the liver is damaged, GGT may leak into the bloodstream. High levels of GGT in the blood may be a sign of liver disease or damage to the bile ducts.

What is the ICD 10 code for elevated liver enzymes?

ICD-10-CM Code for Elevation of levels of liver transaminase levels R74. 01.

Is GGT part of liver function test?

The GGT test is also part of a series of tests known as a liver panel or liver blood tests , which check the levels of other liver enzymes. Other liver enzyme levels that doctors check are alanine aminotransferase (ALT), aspartate aminotransferase (AST), and alkaline phosphatase (ALP).

What does gamma glutamyl transferase do?

GGT functions in the body as a transport molecule, helping to move other molecules around the body. It plays a significant role in helping the liver metabolize drugs and other toxins. GGT is concentrated in the liver, but it's also present in the gallbladder, spleen, pancreas, and kidneys.

What ICD 10 code covers hepatic function panel?

821. Revised descriptor for ICD-10-CM diagnosis code Z77. 29.

What is the code for liver enzymes?

322755: Hepatic Function Panel (7) | Labcorp.

What is R74 01?

R74. 01 Elevation of levels of liver transaminase levels - ICD-10-CM Diagnosis Codes.

Should I be worried if my GGT is high?

Having a higher-than-normal GGT level in your blood may indicate that a condition or disease is damaging your liver. However, the GGT test alone cannot identify the specific cause of the damage. In general, the higher the GGT level, the greater the damage to your liver.

What level of GGT is too high?

In adults, GGT levels in the range of 0 to 30 IU/L are normal. Anything above 30 IU/L could be a sign that your liver isn't working the way it should.

What are the symptoms of high GGT levels?

What Are Symptoms of High GGT Levels?Yellowing skin and eyes (jaundice)Abdominal distension from fluid accumulation (ascites)Pain or tenderness in the upper right side of the abdomen.Enlarged liver (hepatomegaly)Fatigue/tiredness.Feeling unwell (malaise)Lethargy.Loss of appetite.More items...•

Does high GGT mean fatty liver?

Frequently elevated GGT levels can be evaluated as a significant factor for changes in fatty liver. Elevated GGT in non-alcohol drinkers is sometimes a surrogate marker for fatty liver [13, 14]. Our data suggest that frequently elevated GGT levels are probably a good predictor of fatty liver changes to come.

What is GGT in liver?

GGT is useful for diagnosis of liver disease or injury , exclusion of hepatobiliary involvement related to other diseases, and patient management during the resolution of existing disease or following injury. Indications: 1. To provide information about known or suspected hepatobiliary disease, for example: a.

What is GGT in blood?

Description:Gamma glutamyl transferase (GGT) is an intracellular enzyme that appears in blood following leakage from cells. Renal tubules, liver, and pancreas contain high amounts, although the measurement of GGT in serum is almost always used for assessment of Hepatobiliary function. Unlike other enzymes which are found in heart, skeletal muscle, ...

Is GGT a marker of hepatocellular damage?

As well as being a very specific marker of Hepatobiliary function, GGT is also a very sensitive marker for hepatocellular damage. Abnormal concentrations typically appear before elevations of other liver enzymes or biliuria are evident. Obstruction of the biliary tract, viral infection (e.g., hepatitis, mononucleosis), metastatic cancer, ...

Expected Turnaround Time

Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Container

Red-top tube, gel-barrier tube, or green-top (lithium heparin) tube. Do not use oxalate, EDTA, or citrate plasma.

Patient Preparation

The patient should fast for eight hours prior to collection of the specimen. Since there are false elevations in patients on phenytoin and phenobarbital, such patients would be better served with orders for one of the alternate tests − leucine aminopeptidase (LAP) or 5′ nucleotidase.

Limitations

Acetaminophen toxicity has been reported to cause an in vivo increase. The combination of high alkaline phosphatase and normal GT does not rule out liver disease completely. Activity is not significantly increased in sera of patients with lymphoma (unless there is hepatic involvement by the lymphoma).

Additional Information

GT is helpful to work up elevated alkaline phosphatase values. GT is a biliary excretory enzyme which is more specific for hepatic disease than is alkaline phosphatase. It is normal in most instances of renal failure. 8 GT has no origin in bone or placenta, unlike alkaline phosphatase, and age beyond infancy does not influence GT levels.
