ICD Code R74.0

ICD code R74.0 is used to identify a condition where there is a nonspecific elevation in the levels of transaminase and lactic acid dehydrogenase (LDH) in the blood. This code is typically used when these enzyme levels are higher than normal, but the exact cause of the elevation is not specified. Elevated transaminase levels can indicate liver damage or disease, while increased LDH levels can suggest tissue damage or disease in various parts of the body. This code helps healthcare providers document and track these abnormal lab findings for further investigation and management.

1. Elevated Transaminase Levels: Use this code when there is a documented nonspecific elevation in transaminase levels, such as alanine aminotransferase (ALT) or aspartate aminotransferase (AST), without a definitive diagnosis of liver disease or other specific conditions.

2. Elevated Lactic Acid Dehydrogenase (LDH) Levels: Apply this code when there is a nonspecific increase in LDH levels, which may indicate tissue damage or disease but lacks a specific diagnosis.

3. Absence of Specific Diagnosis: This code is appropriate when elevated enzyme levels are present, but a specific underlying condition, such as viral hepatitis or myocardial infarction, has not been identified.

4. Routine Laboratory Testing: Use this code when elevated transaminase or LDH levels are discovered during routine laboratory testing, and further investigation is required to determine the cause.

5. Monitoring of Known Conditions: This code can be used when monitoring patients with known conditions that may cause enzyme elevation, but the specific cause of the current elevation is not yet determined.

6. Follow-up Testing: Apply this code when follow-up testing is conducted to monitor previously identified nonspecific enzyme elevations, and a specific diagnosis is still pending.

7. Clinical Evaluation: Use this code when elevated enzyme levels are part of a broader clinical evaluation, and the healthcare provider is in the process of ruling out various potential causes.

For the ICD code R74.0, which indicates nonspecific elevation of levels of transaminase and lactic acid dehydrogenase [LDH], the relevant CPT codes that may be applicable for treatment or further diagnostic evaluation include:

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

2. CPT 84450 - Transferase; aspartate amino (AST) (SGOT): This test measures the level of AST in the blood, which is often elevated in liver conditions.

3. CPT 84460 - Alanine Aminotransferase (ALT) (SGPT): This test measures the level of ALT in the blood, another enzyme that can be elevated in liver conditions.

4. CPT 83615 - Lactate Dehydrogenase (LD) (LDH): This test measures the level of LDH in the blood, which can be elevated in various conditions, including liver disease.

5. CPT 84478 - Triglycerides: While not directly related to transaminase levels, triglyceride testing can be part of a broader metabolic panel when evaluating liver function.

These CPT codes are often used in conjunction with ICD code R74.0 to provide a comprehensive evaluation of liver function and to help identify potential underlying causes of the enzyme elevation. Always consult with a healthcare professional or coding specialist to ensure accurate coding and billing practices.
