Abnormality of albumin

This code signifies an abnormal level of albumin in the blood, which can manifest as either hypoalbuminemia (low albumin) or hyperalbuminemia (high albumin). Albumin is a major protein produced by the liver, crucial for maintaining oncotic pressure and transporting various substances.

Use this code when laboratory results indicate an albumin level outside the normal reference range, and the specific cause is either unknown or not yet definitively diagnosed. It is appropriate for documenting an abnormal lab finding that requires further investigation or monitoring. Documentation should clearly state the abnormal albumin level and the physician's assessment of this finding.

• Do not use this code if a definitive diagnosis explaining the abnormal albumin (e.g., liver failure, nephrotic syndrome, severe malnutrition) is already established and coded.
• Sequence this code as a secondary diagnosis when a more specific underlying condition is identified and coded as the primary diagnosis.
• Ensure the medical record explicitly documents the abnormal albumin level from laboratory tests.
