H74.8X2

What This Code Means

This code describes a specific disorder affecting the left middle ear and mastoid bone that doesn't fit into other standard categories. The middle ear is the space behind the eardrum, and the mastoid is the bone behind the ear that can become infected or diseased.

Coding Tips

• •Use this code only when the specific middle ear or mastoid condition is documented but doesn't match more specific H74 codes; always verify the laterality is confirmed as left
• •Review the medical record for documentation of the exact nature of the disorder, as this is a catch-all code and more specific codes may be available depending on the clinical presentation
