About K06.8
K06.8 is the ICD-10-CM diagnosis code for other specified disorders of gingiva and edentulous alveolar ridge. It belongs to category K06 (other disorders of gingiva and edentulous alveolar ridge), block K00-K14 (diseases of oral cavity and salivary glands) and chapter 11 (diseases of the digestive system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within K06, choose K06.8 (Other specified disorders of gingiva and edentulous alveolar ridge) only when documentation doesn't support a more specific option: gingival recession (K06.0), gingival enlargement (K06.1), gingival and edentulous alveolar ridge lesions associated with trauma (K06.2), horizontal alveolar bone loss (K06.3) and disorder of gingiva and edentulous alveolar ridge, unspecified (K06.9).
The conditions in its Excludes2 note aren't part of K06.8, but may be coded alongside it if the patient has both: gingival cyst (K09.0).
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 523.8 (other specified periodontal diseases).

Common questions about K06.8
Is K06.8 billable?
- Yes. K06.8 is a billable/specific ICD-10-CM code valid for FY2027 (October 1, 2026 – September 30, 2027).
Can K06.8 be used as a principal diagnosis?
- Yes. The Medicare Code Editor doesn't restrict K06.8 as a principal diagnosis.
Is K06.8 a CC or MCC?
- No. K06.8 is neither a CC nor an MCC under MS-DRG v44.0.
What DRG does K06.8 group to?
- K06.8 is used in the MS-DRG v44.0 logic for MS-DRG 011 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with MCC), MS-DRG 012 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy with CC), MS-DRG 013 (Tracheostomy for Face, Mouth and Neck Diagnoses or Laryngectomy without CC/MCC), MS-DRG 157 (Dental and Oral Diseases with MCC), MS-DRG 158 (Dental and Oral Diseases with CC) and MS-DRG 159 (Dental and Oral Diseases without CC/MCC). Which one applies depends on whether it is the principal diagnosis and on the rest of the claim.
What is the ICD-9 code for K06.8?
- The CMS General Equivalence Mappings map K06.8 to ICD-9-CM 523.8.
