Granulation of postmastoidectomy cavity, bilateral ears

This code signifies the presence of granulation tissue within the mastoidectomy cavity in both ears following a surgical procedure to remove diseased mastoid air cells. This condition indicates an abnormal healing response or chronic inflammation within the surgical site.

Assign this code when documentation explicitly states bilateral granulation tissue in a post-mastoidectomy cavity. This typically occurs during follow-up examinations for patients who have undergone mastoidectomy and are experiencing persistent or new symptoms related to the surgical site. Documentation should specify the laterality as bilateral.

• Ensure documentation clearly specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Distinguish from other post-procedural complications like infection (e.g., H95.0-) or cholesteatoma (e.g., H71.-).
• Code also any associated symptoms or underlying conditions, such as chronic otitis media, if still present and relevant.
