About coding Notching nose
The ICD-10-CM code for Notching nose is Q30.2 (Fissured, notched and cleft nose).
Within Q30 (congenital malformations of nose), Q30.2 is specifically for Fissured, notched and cleft nose. Related codes cover Choanal atresia (Q30.0), agenesis and underdevelopment of nose (Q30.1), congenital perforated nasal septum (Q30.3), other congenital malformations of nose (Q30.8) and congenital malformation of nose, unspecified (Q30.9).
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 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.
