Granulation of postmastoidectomy cavity, right ear

This code signifies the presence of granulation tissue within the cavity remaining after a mastoidectomy procedure, specifically affecting the right ear. Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process, but in this context, it indicates an abnormal or excessive growth within the surgical defect.

Apply this code when documentation clearly indicates the development of granulation tissue within a post-surgical mastoid cavity on the patient's right side. This typically occurs as a complication of the healing process following a mastoidectomy. Supporting documentation would include operative reports, physician notes describing examination findings, or imaging reports confirming the presence of granulation.

• Ensure the documentation specifies "granulation" and not another post-mastoidectomy complication like infection or cholesteatoma.
• Verify the laterality (right ear) is explicitly stated in the clinical record.
• Consider sequencing this code after a code for the underlying condition that necessitated the mastoidectomy, if still active and relevant.
