About M27.63

M27.63 is the ICD-10-CM diagnosis code for Post-osseointegration mechanical failure of dental implant. It belongs to category M27 (other diseases of jaws), block M26-M27 (dentofacial anomalies [including malocclusion] and other disorders of jaw) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M27.6 (endosseous dental implant failure), M27.63 is specifically for Post-osseointegration mechanical failure of dental implant. Related codes cover Osseointegration failure of dental implant (M27.61), Post-osseointegration biological failure of dental implant (M27.62) and other endosseous dental implant failure (M27.69).

The conditions in its Excludes2 note aren't part of M27.63, but may be coded alongside it if the patient has both: cracked tooth (K03.81), fractured dental restorative material with loss of material (K08.531), fractured dental restorative material without loss of material (K08.530) and fractured tooth (S02.5).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC, relative weight 5.6154), DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC, relative weight 4.381), DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC, relative weight 2.7307), DRG 157 (Dental and Oral Diseases with MCC, relative weight 1.809), DRG 158 (Dental and Oral Diseases with CC, relative weight 0.9366) and DRG 159 (Dental and Oral Diseases without CC/MCC, relative weight 0.6893), in Pre-MDC and MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 525.73 (Post-osseointegration mechanical failure of dental implant).
