H70.093
BillableAcute mastoiditis with other complications, bilateral
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes a serious ear infection affecting the mastoid bone (the bone behind the ear) on both sides of the head, with additional complications beyond the basic infection. The mastoid bone has become inflamed and infected, causing problems in both ears simultaneously.
Coding Tips
- •Verify documentation specifies 'bilateral' involvement before assigning this code; if only one side is affected, use H70.091 instead
- •Ensure the documentation identifies what specific complications are present (such as subperiosteal abscess, fistula, or other complications) as this affects code selection and severity assessment
