ICD-10 code for Calcifying odontogenic cyst

The ICD-10-CM code for Calcifying odontogenic cyst is D16.5 (Benign neoplasm of lower jaw bone). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on D16.5.

Within D16 (benign neoplasm of bone and articular cartilage), D16.5 is specifically for benign neoplasm of lower jaw bone. Related codes cover scapula and long bones of upper limb (D16.0), short bones of upper limb (D16.1), long bones of lower limb (D16.2), short bones of lower limb (D16.3), bones of skull and face (D16.4), vertebral column (D16.6), ribs, sternum and clavicle (D16.7), pelvic bones, sacrum and coccyx (D16.8) and 1 more.

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.
