Cryoglobulinemia

This code represents a condition characterized by the presence of cryoglobulins, abnormal immunoglobulins that precipitate in the cold and redissolve upon rewarming. These cryoglobulins can lead to inflammation and damage in various organs, most commonly affecting small blood vessels. The clinical manifestations are diverse and can include vasculitis, purpura, arthralgia, neuropathy, and kidney disease.

Use this code when documenting a confirmed diagnosis of cryoglobulinemia, regardless of the underlying cause (e.g., essential, associated with hepatitis C, autoimmune diseases, or lymphoproliferative disorders). Documentation should clearly indicate the presence of cryoglobulins and associated clinical findings. This code is appropriate for both initial diagnoses and follow-up encounters for managing the condition.

• Always code any underlying conditions, such as hepatitis C (B17.1x, B18.2), autoimmune diseases, or lymphoproliferative disorders, in addition to this code.
• Do not confuse this with other types of vasculitis unless cryoglobulinemia is explicitly documented as the cause.
• Ensure documentation specifies the type of cryoglobulinemia (Type I, II, or III) if known, as this can impact treatment and prognosis, though the ICD-10-CM code does not differentiate.
