ICD10 code of Cholesteatoma and ICD9 code

The ICD-10 code for cholesteatoma of the middle ear is H71, which includes various sub-classifications depending on the specific location and type of the lesion. Under the older ICD-9-CM coding system, cholesteatoma was classified under code 385.3, with further specificity based on the anatomical site of the growth.

What exactly is a cholesteatoma?

A cholesteatoma is an abnormal, noncancerous skin growth that can develop in the middle section of your ear, behind the eardrum. It often develops as a cyst or pouch that sheds layers of old skin. Over time, these skin cells accumulate, and the cholesteatoma can increase in size, potentially damaging the delicate bones of the middle ear or even affecting the inner ear, which can lead to hearing loss, dizziness, and ear drainage. While the term "tumor" is sometimes used, it is important to note that a cholesteatoma is not a form of cancer, though it requires medical intervention to prevent progressive damage to the auditory system.

How are ICD codes used for Cholesteatoma?

Medical coding, such as the ICD-10 H71 series, is essential for physicians and hospitals to accurately document the diagnosis of cholesteatoma for insurance, research, and clinical tracking purposes. These codes allow healthcare systems to monitor the prevalence of the condition, which is significant given that over 1,133 members of the DiseaseMaps community have shared their personal experiences with this diagnosis. Precise coding helps in distinguishing between congenital cholesteatoma and acquired cholesteatoma, which is critical for determining the most appropriate surgical approach.

What are the clinical indicators and diagnostic signs?

Identifying a cholesteatoma early is vital to preserving hearing and preventing complications. If you suspect you have this condition, look for these common clinical signs:

• Persistent ear drainage: Often characterized by a foul odor due to the trapped skin cells and potential secondary infection.


• Progressive hearing loss: This occurs as the mass interferes with the vibration of the ossicles (middle ear bones).


• Vertigo and imbalance: A sign that the cholesteatoma may be encroaching on the inner ear or vestibular system.


• Otalgia (ear pain): Chronic discomfort or pressure behind or in the ear, frequently worsening at night.


• Facial nerve involvement: In severe, advanced cases, facial muscle weakness or paralysis may occur if the growth affects the facial nerve canal.

How is this condition treated?

Because a cholesteatoma has the potential to erode bone and spread, surgery is the gold standard for treatment. The primary goal is to completely remove the diseased tissue and create a "safe" ear. Depending on the extent of the growth, this may involve a procedure known as tympanomastoidectomy. Following surgery, long-term monitoring is required, as there is a possibility of recurrence, necessitating regular follow-up appointments with an otolaryngologist.

Next steps

• Consult an Otolaryngologist (ENT specialist) immediately if you experience persistent ear drainage, hearing loss, or chronic ear pressure.


• Request a high-resolution CT scan of the temporal bone, which is the standard imaging modality to evaluate the extent of the cholesteatoma.


• Join the DiseaseMaps community to connect with over 1,100 other individuals who have navigated the diagnosis and surgical treatment of this condition.


• Discuss surgical options and potential reconstruction of the middle ear bones with your surgeon to understand the expected outcomes for your hearing.
