ICD Code R94.5

ICD code R94.5 is used to indicate abnormal results of liver function studies. This code is applied when laboratory tests reveal irregularities in liver function, which may suggest liver disease or dysfunction. It is important for healthcare providers to document this code accurately to ensure proper diagnosis, treatment planning, and billing.

When considering the use of the ICD code for abnormal results of liver function studies, healthcare providers should evaluate the following diagnostic criteria and symptoms:

1. Elevated Liver Enzymes:

- Alanine aminotransferase (ALT) levels above the normal range.

- Aspartate aminotransferase (AST) levels above the normal range.

- Alkaline phosphatase (ALP) levels above the normal range.

2. Bilirubin Abnormalities:

- Total bilirubin levels that are higher than normal.

- Direct (conjugated) bilirubin levels that are elevated.

3. Abnormal Albumin Levels:

- Serum albumin levels that are lower than the normal range.

4. Prolonged Prothrombin Time (PT):

- PT that is longer than the normal range, indicating potential liver dysfunction.

5. Gamma-Glutamyl Transferase (GGT) Elevation:

- GGT levels that are higher than normal, often used to assess liver function and bile duct issues.

6. Presence of Jaundice:

- Yellowing of the skin and eyes, indicating potential liver dysfunction.

7. Unexplained Fatigue or Weakness:

- Persistent tiredness or weakness that cannot be attributed to other conditions.

8. Nausea or Vomiting:

- Frequent episodes of nausea or vomiting without a clear cause.

9. Abdominal Pain or Discomfort:

- Pain or discomfort in the upper right quadrant of the abdomen.

10. Dark Urine or Pale Stools:

- Changes in urine or stool color that suggest liver issues.

These criteria and symptoms should be assessed in conjunction with a comprehensive clinical evaluation to determine the appropriateness of using the ICD code for abnormal liver function study results.

For the ICD code R94.5, which pertains to abnormal results of liver function studies, the relevant CPT codes that may be applicable for treatment or further diagnostic evaluation include:

1. 80076 - Hepatic Function Panel: This panel includes tests for total protein, albumin, bilirubin (total and direct), alkaline phosphatase, AST (SGOT), and ALT (SGPT).

2. 84460 - Alanine Aminotransferase (ALT) Test: Measures the level of ALT in the blood, an enzyme found in the liver.

3. 84450 - Aspartate Aminotransferase (AST) Test: Measures the level of AST in the blood, another enzyme found in the liver.

4. 82247 - Bilirubin, Total: Measures the total amount of bilirubin in the blood.

5. 82248 - Bilirubin, Direct: Measures the direct bilirubin level in the blood.

6. 84155 - Total Protein Test: Measures the total amount of protein in the blood.

7. 82040 - Albumin Test: Measures the level of albumin, a protein made by the liver.

8. 84075 - Alkaline Phosphatase Test: Measures the level of alkaline phosphatase enzyme in the blood.

These CPT codes are typically used in conjunction with ICD code R94.5 to further investigate and manage abnormal liver function test results. It's important for healthcare providers to select the appropriate CPT codes based on the specific clinical scenario and the tests or procedures being performed.
