About coding auricle cervical
The ICD-10-CM code for auricle cervical is Q18.2 (Other branchial cleft malformations).
Within Q18, choose Q18.2 (Other branchial cleft malformations) only when documentation doesn't support a more specific option: sinus, fistula and cyst of branchial cleft (Q18.0), preauricular sinus and cyst (Q18.1), Webbing of neck (Q18.3), Macrostomia (Q18.4), Microstomia (Q18.5), Macrocheilia (Q18.6), Microcheilia (Q18.7), other specified congenital malformations of face and neck (Q18.8) 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 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 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.
