ICD-10 Code H73.019 – Bullous myringitis, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.019 – Bullous myringitis, unspecified ear
What it is
H73.019 identifies bullous myringitis affecting an unspecified ear. It means the eardrum has blister-like lesions, but the record does not specify left or right side.
Clinical signs
Typical findings include ear pain and visible bullae on the tympanic membrane. Hearing changes or middle ear symptoms may be present; clinical features vary, so refer to documentation.
When to use this code
Use this code when the clinician documents bullous myringitis and does not identify the affected ear. It also fits when the note confirms eardrum bullae, but laterality is absent or unclear. Code from the documented diagnosis, not from suspected otitis alone.
Do not use for
Do not use H73.019 if the record specifies left or right ear, because a laterality-specific code is available. Do not use it for nonspecific ear pain or other middle ear disorders without documented bullous myringitis.
Coding tip
Check the assessment for laterality before assigning H73.019.
