ICD-10 code for Retrusion

The ICD-10-CM code for Retrusion is M26.09 (Other specified anomalies of jaw size).

Within M26.0, choose M26.09 (Other specified anomalies of jaw size) only when documentation doesn't support a more specific option: unspecified anomaly of jaw size (M26.00), maxillary hyperplasia (M26.01), maxillary hypoplasia (M26.02), mandibular hyperplasia (M26.03), mandibular hypoplasia (M26.04), macrogenia (M26.05), microgenia (M26.06) and excessive tuberosity of jaw (M26.07).

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.
