Other disorders of plasma protein metabolism

This code represents various uncommon or unspecified abnormalities in the production, breakdown, or function of plasma proteins, excluding those specifically classified elsewhere (e.g., amyloidosis, macroglobulinemia). It encompasses conditions where the balance or structure of plasma proteins is disturbed, leading to diverse clinical manifestations.

Use this code for documented plasma protein disorders that do not fit more specific ICD-9-CM categories. This includes conditions like essential cryoglobulinemia (without an underlying disease specified), dysgammaglobulinemia not otherwise specified, or other unclassified plasma protein abnormalities. Documentation should clearly indicate a plasma protein disorder that lacks a more precise diagnostic code.

• Avoid using this code if a more specific diagnosis for a plasma protein disorder (e.g., amyloidosis, specific paraproteinemia) is available.
• Always review the medical record for any underlying conditions or specific types of plasma protein disorders that would warrant a more precise code.
• Consider sequencing this code after any primary disease causing the plasma protein abnormality, if applicable.
