Postprocedural seroma of ear/mastd following other procedure

This code represents the formation of a seroma (a collection of serous fluid) in the ear or mastoid region that develops as a complication after a surgical or other invasive procedure. It specifically indicates that the seroma is a direct consequence of the intervention, excluding those following cochlear implant or mastoidectomy.

Use this code when documentation clearly indicates a seroma of the ear or mastoid process occurring post-procedure, and the procedure was not a cochlear implant or mastoidectomy. Supporting documentation should specify the anatomical site (ear/mastoid) and the causal link to a prior intervention.

• Always sequence this code after the code identifying the underlying complication or the procedure that led to the seroma, if applicable.
• Distinguish from seromas following cochlear implant (H95.31) or mastoidectomy (H95.32).
• Ensure the documentation specifies "postprocedural" to differentiate from spontaneous seromas or those due to trauma.
