J35.9
ICD-10-CMThis code signifies a persistent, long-standing condition affecting both the tonsils and adenoids, where the specific nature or etiology of the disease is not documented. It indicates a chronic pathological process without further detail regarding inflammation, hypertrophy, or other specific diagnoses.
This code is appropriate when the medical record clearly states a chronic disease of both tonsils and adenoids, but lacks specificity regarding the exact type of disease (e.g., chronic tonsillitis, chronic adenoiditis, hypertrophy). It should be used when the provider's documentation is generalized and does not allow for a more precise diagnosis from codes within the J35 category.
