Hereditary alpha tryptasemia is a genetic condition characterized by elevated serum tryptase levels due to mutations in the TPSAB1 gene. Clinically significant as it may lead to mast cell activation disorders, accurate coding with ICD-10 Code D89.44 is essential for diagnosis, documentation, billing, and public health reporting.
ICD-10 Code D89.44 represents Hereditary alpha tryptasemia, a genetic disorder associated with increased tryptase levels. This code should be used in clinical documentation when diagnosing patients with this condition, ensuring proper billing and facilitating the tracking of related health outcomes.
Hereditary alpha tryptasemia is caused by mutations in the TPSAB1 gene, leading to excessive production of tryptase by mast cells. This condition can result in various symptoms, including anaphylaxis and other mast cell-related disorders, necessitating medical attention.
ICD-10 Code D89.44 is utilized in SOAP notes to document the diagnosis of Hereditary alpha tryptasemia. It aids in capturing patient symptoms, assessments, and treatment plans, relevant in both acute and chronic care settings.
In SOAP notes, ICD-10 Code D89.44 connects subjective patient reports and objective clinical findings to a formal diagnosis of Hereditary alpha tryptasemia, ensuring continuity of care and supporting accurate billing.
Hereditary alpha tryptasemia may require hospitalization for severe symptoms. Treatment focuses on managing symptoms and preventing complications.
