About K08.0
K08.0 is the ICD-10-CM diagnosis code for Exfoliation of teeth due to systemic causes. It belongs to category K08 (other disorders of teeth and supporting structures), 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 K08 (other disorders of teeth and supporting structures), K08.0 is specifically for Exfoliation of teeth due to systemic causes. Related codes cover complete loss of teeth (K08.1), atrophy of edentulous alveolar ridge (K08.2), retained dental root (K08.3), partial loss of teeth (K08.4), unsatisfactory restoration of tooth (K08.5), other specified disorders of teeth and supporting structures (K08.8) and disorder of teeth and supporting structures, unspecified (K08.9).
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 525.0 (Exfoliation of teeth due to systemic causes).
