Polyclonal hypergammaglobulinemia

This code represents an elevated level of multiple types of immunoglobulins (antibodies) in the blood, indicating a generalized immune system activation rather than a monoclonal proliferation. It signifies a non-specific immune response to various stimuli, such as chronic infections, autoimmune diseases, or liver conditions.

Use this code when documentation explicitly states polyclonal hypergammaglobulinemia, often identified through serum protein electrophoresis or immunoglobulin quantification. It is appropriate for conditions where the immune system is broadly stimulated, leading to an increase in diverse antibody populations.

• Do not confuse with monoclonal gammopathy (e.g., D47.2), which involves a single type of immunoglobulin.
• Always code the underlying cause of the hypergammaglobulinemia first, if known and documented (e.g., chronic hepatitis, autoimmune disorder).
• Ensure documentation specifies "polyclonal" to differentiate from unspecified hypergammaglobulinemia (R77.1).
