273.9
ICD-9-CMThis code signifies a metabolic disturbance involving plasma proteins where the specific type of disorder is not identified. It indicates an abnormal level or function of proteins found in the blood plasma, without further diagnostic clarity.
This code is appropriate when documentation indicates an abnormality in plasma protein metabolism, such as dysproteinemia or hyperproteinemia, but the physician has not specified the underlying cause or specific protein affected. It should be used when more specific diagnostic codes are unavailable due to incomplete clinical information.
