Other disorders of tympanic membrane (H73)

The ICD-10 codes in the H73 category are used to classify various disorders affecting the tympanic membrane (eardrum), including acute and chronic inflammation as well as structural abnormalities. These codes help specify conditions such as acute myringitis, bullous myringitis, and atrophic tympanic membrane, among others.

This section covers a range of tympanic membrane issues like acute myringitis (coded H73.0), which reflects inflammation sometimes called "ear drum infection" and can be detailed further by ear side (right ear H73.001, left ear H73.002, bilateral H73.003). Bullous myringitis (H73.01) involves painful blisters on the eardrum and is also coded by ear side. Chronic conditions such as chronic myringitis (H73.1) and nonspecific myringitis (H73.2) describe long-term inflammations. Other specified disorders (H73.8) include atrophic changes or retraction pockets, which may be described as "vesicles on tympanic membrane" or "retraction of tympanic membrane." The codes also allow for identifying unspecified cases (H73.9) and differentiate disorders by ear, aiding precise communication in medical documentation. Knowing the ICD-10 code for specific tympanic membrane disorders assists both clinicians and coders in accurate coding and reporting of these ear conditions.
