ICD-10 code for gingiva disease

The ICD-10-CM code for gingiva disease is K06.9 (Disorder of gingiva and edentulous alveolar ridge, unspecified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on K06.9.

Within K06, choose K06.9 (Disorder of gingiva and edentulous alveolar ridge, unspecified) 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 other specified disorders of gingiva and edentulous alveolar ridge (K06.8).

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.
