Post-osseointegration biological failure of dental implant

This code signifies the failure of a previously integrated dental implant due to biological factors after the initial healing and osseointegration period. This means the implant, which had successfully fused with the bone, has now lost its stability and function due to issues like peri-implantitis, bone loss around the implant, or other biological complications.

Use this code when documentation clearly indicates a dental implant that had achieved osseointegration is now failing due to biological reasons. This applies to cases where the implant needs removal, revision, or is causing ongoing symptoms due to this biological failure. Supporting documentation would include clinical notes detailing peri-implant bone loss, infection, or mobility of a previously stable implant.

• Differentiate from initial implant non-osseointegration (e.g., M27.61), which occurs before successful integration.
• Always look for documentation specifying "post-osseointegration" and "biological failure" to support this code.
• Consider sequencing with codes for underlying conditions like peri-implantitis (K05.6-) if applicable and documented.
