icd 10 code screening for ggt

Full Answer

What ICD-10 code covers GGT?

8: Abnormal levels of other serum enzymes.

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 a GGT screening?

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 CPT code for GGT?

LOINC MapOrder CodeOrder Code NameOrder Loinc001958GGT2324-2

What ICD-10 code covers hepatic function panel?

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

What is the ICD-10 code for abnormal liver enzymes?

ICD-10 code R94. 5 for Abnormal results of liver function studies is a medical classification as listed by WHO under the range - Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified .

Why do I need a GGT blood test?

Doctors use the gamma-glutamyl transferase (GGT) test to diagnose liver problems. They measure GGT if they suspect damage to the liver, bile ducts, chronic alcohol use, or certain bone diseases. In the GGT test, a healthcare professional measures the levels of GGT in a sample of blood.

What is GGT labcorp?

GGT is elevated in the blood in most diseases that cause damage to the liver or bile ducts. This test measures the level of GGT in a blood sample. Normally, GGT is present in low levels, but when the liver is injured, the GGT level can rise.

Is GGT and GGTP the same?

It's most often tested alongside an alkaline phosphatase (ALP) blood test, which measures another type of enzyme that's found in your liver and bones. Other names for a gamma-glutamyl transferase (GGT) blood test include: Gamma-glutamyl transpeptidase. GGTP.

Does Medicare cover CPT code 83036?

(2) the service must be medically necessary or indicated. Once these two criteria are met, Medicare pays for most clinical laboratory tests based on the Laboratory Fee Schedule.

Useful For

Diagnosing and monitoring hepatobiliary disease, it is currently the most sensitive enzymatic indicator of liver disease

Specimen Requirements

Serum or plasma should be physically separated from cells as soon as possible with a maximum limit of two hours from the time of collection.

Test Classification and CPT Coding

LCD or NCD test. ICD-10 code is required for this test. When appropriate, obtain a properly executed ABN and submit the ABN with test order (s). See “Medical Necessity and Advanced Beneficiary Notice (ABN) Policy and Form” under "Resources" for a copy of a form and additional information.

What does rhogam mean in pregnancy?

In pregnant women, the results indicate whether she is Rh positive or negative and whether she may be a candidate for receiving Rh immune globulin (RhoGAM) to prevent her from potentially developing antibodies against fetal red blood cells. Note: Some pregnant women might express weak D antigen.

What is a blood typing test?

Blood typing is a screening test to determine blood groups and Rh antigen for blood transfusion and pregnancy. The four blood groups A, B, O, and AB are determined by the presence of antigens A and B or their absence (O) on a patient's red blood cells. In addition to ABO grouping, most immunohematology testing includes evaluation of Rh typing tests for Rh (D) antigen. Blood cells that express Rh (D) antigen are Rh positive. Red blood cells found lacking Rh (D) are considered Rh negative. Rh typing is also important during pregnancy because of the potential for mother and fetus Rh incompatiblity. If the mother is Rh negative but the father is Rh positive, the fetus may be positive for the Rh antigen. As a result, the mother’s body could develop antibodies against the Rh antigen. These antibodies may cross the placenta and cause destruction of the baby’s red blood cells, resulting in a condition known as hemolytic disease of the fetus and newborn.

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.
