Other acquired abnormalities of right ear ossicles

This code signifies any non-congenital structural or functional defect of the ossicles (malleus, incus, stapes) in the right ear that is not specifically classified elsewhere. These abnormalities can result from trauma, infection, or degenerative processes, impacting sound conduction.

Apply this code when documentation specifies an acquired, unspecified, or "other" abnormality of the right ear ossicles, such as ossicular chain discontinuity, fixation, or erosion, without a more specific ICD-10-CM code available. Supporting documentation should clearly indicate the laterality (right ear) and the acquired nature of the condition.

• Ensure the documentation explicitly states "right ear" to support laterality.
• Avoid using this code if a more specific code for an acquired ossicular abnormality (e.g., H74.31 for discontinuity) is available.
• Always review the medical record for the underlying cause of the acquired abnormality, as an additional code may be necessary to fully describe the patient's condition.
