About coding roots buried
The ICD-10-CM code for roots buried is K08.3 (Retained dental root).
Within K08 (other disorders of teeth and supporting structures), K08.3 is specifically for retained dental root. Related codes cover Exfoliation of teeth due to systemic causes (K08.0), complete loss of teeth (K08.1), atrophy of edentulous alveolar ridge (K08.2), 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.
