ICD-10 code for parotid deformity

The ICD-10-CM code for parotid deformity is Q38.4 (Congenital malformations of salivary glands and ducts). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q38.4.

Within Q38 (other congenital malformations of tongue, mouth and pharynx), Q38.4 is specifically for congenital malformations of salivary glands and ducts. Related codes cover congenital malformations of lips, not elsewhere classified (Q38.0), Ankyloglossia (Q38.1), Macroglossia (Q38.2), other congenital malformations of tongue (Q38.3), congenital malformations of palate, not elsewhere classified (Q38.5), other congenital malformations of mouth (Q38.6), congenital pharyngeal pouch (Q38.7) and other congenital malformations of pharynx (Q38.8).

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 154 (Other Ear, Nose, Mouth and Throat Diagnoses with MCC, relative weight 1.5921), DRG 155 (Other Ear, Nose, Mouth and Throat Diagnoses with CC, relative weight 0.9322) and DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659), 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.
