Hypertrophy of adenoids

This code signifies an abnormal enlargement of the adenoids, which are lymphoid tissues located in the nasopharynx. This hypertrophy can obstruct the airway, leading to various symptoms such as difficulty breathing, snoring, and recurrent ear infections. It represents a structural abnormality without active inflammation.

Assign this code when documentation clearly indicates an enlarged adenoid without any mention of acute or chronic inflammation (adenoiditis). This diagnosis is often made during an ENT examination or imaging studies. Supporting documentation includes physician notes describing adenoid hypertrophy and the absence of inflammatory signs.

• Do not use this code if adenoiditis is also present; refer to the Excludes1 note for appropriate coding.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, such as for evaluation or surgical planning.
• Ensure the documentation explicitly states "hypertrophy" or "enlargement" of the adenoids and does not describe an inflammatory process.
