ICD-10 Code H73.011 – Bullous myringitis, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H73.011 – Bullous myringitis, right ear
What it is
H73.011 identifies bullous myringitis affecting the right eardrum. It means there are blister-like lesions on the tympanic membrane in the right ear.
Clinical signs
Common findings include ear pain, a red or inflamed tympanic membrane, and visible bullae on otoscopic exam. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bullous myringitis specifically in the right ear. Code it from the exam note or assessment when the side is clearly stated. If laterality is not documented, check documentation before assigning a side-specific code.
Do not use for
Do not use this code for left ear, bilateral, or unspecified bullous myringitis. Do not assign it for other causes of ear pain or nonspecific otitis without documentation of bullous myringitis.
Coding tip
Confirm laterality in the provider note, because H73.011 is only for the right ear.
