Cochlear implant status

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A patient has a cochlear implant, which is an electronic device surgically placed in the ear to help provide a sense of sound to people with severe hearing loss.

Coding Tips

  • Document whether the implant is unilateral or bilateral for complete clinical documentation
  • Use this code to indicate status; pair with complication codes if the patient experiences device-related problems
