Other abnormal blood chemistry

This code signifies the presence of abnormal findings in a patient's blood chemistry panel that are not specifically classified elsewhere. It indicates a deviation from normal reference ranges for various blood components, such as electrolytes, enzymes, or metabolites, when a more precise diagnosis is unavailable.

This code is appropriate when laboratory results indicate an abnormal blood chemistry finding, but the specific nature or cause of the abnormality is not yet determined or is not covered by a more specific ICD-9-CM code. It is often used as a temporary or provisional diagnosis while further investigation is pending, or when the abnormality is considered non-specific. Documentation should clearly state an abnormal lab value without a definitive diagnosis.

• Avoid using this code if a more specific diagnosis for the abnormal blood chemistry is known (e.g., hyperkalemia, elevated liver enzymes due to hepatitis).
• This code should generally not be the primary diagnosis if a definitive condition causing the abnormality has been identified and can be coded.
• Review the entire lab panel and clinical notes to ensure no other specific diagnosis can be assigned before resorting to this non-specific code.
