What is the difference between a simple mastoidectomy 69501 and a complete mastoidectomy 69502?


SuperCoder Answered Thu 05th of April, 2012 15:25:43 PM

A simple mastoidectomy is generally performed to aid in the drainage of an infection. It is the removal of viable mucosa and disease from the mastoid cells along with the creation of a tympanic antrum opening, resulting in the improvement of ventilation.
If the physician documents a complete mastoidectomy, you should report 69502. During this procedure, the otolaryngologist attempts to remove all air cells and includes an exploration of the entire “attic” or “epitympanum.”
Complete mastoidectomy involves middle-ear work.
