ICD Code R74.02

ICD code R74.02 is elevation of levels of lactic acid dehydrogenase (LDH), indicating that a patient's blood test shows higher than normal LDH enzyme levels, which can be a sign of tissue damage or disease.

1. Laboratory results indicate elevated levels of lactic acid dehydrogenase (LDH) above the normal reference range.

2. The elevation is not attributable to a specific, identified disease process at the time of coding.

3. The patient may present with nonspecific symptoms such as fatigue, weakness, or malaise, but these are not required for code assignment.

4. The elevated LDH is documented by the provider as a clinically significant finding.

5. The elevation is not explained by hemolysis, myocardial infarction, liver disease, or other specific conditions with their own diagnostic codes.
