Other disorders following mastoidectomy, right ear

This code signifies any post-mastoidectomy complication or disorder affecting the right ear, excluding recurrent cholesteatoma. These conditions are typically sequelae of the surgical procedure, such as persistent drainage, granulation tissue, or other structural changes that are not specifically classified elsewhere.

Use this code when documentation clearly indicates a new or ongoing issue in the right ear directly attributable to a prior mastoidectomy, and the specific disorder is not better described by a more precise code. This code is appropriate when the physician's notes describe "other post-mastoidectomy complications, right ear" or similar non-specific but surgery-related issues.

• Always specify laterality (right, left, bilateral) when documented.
• Ensure the documentation explicitly links the disorder to a previous mastoidectomy.
• Do not use for recurrent cholesteatoma, which has its own specific code (H95.0-).
