About coding hemifacial atrophy
The ICD-10-CM code for hemifacial atrophy is Q67.4 (Other congenital deformities of skull, face and jaw). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q67.4.
Within Q67, choose Q67.4 (Other congenital deformities of skull, face and jaw) only when documentation doesn't support a more specific option: congenital facial asymmetry (Q67.0), congenital compression facies (Q67.1), Dolichocephaly (Q67.2), Plagiocephaly (Q67.3), congenital deformity of spine (Q67.5), pectus excavatum (Q67.6), pectus carinatum (Q67.7) and other congenital deformities of chest (Q67.8).
Don't report Q67.4 together with the conditions in its Excludes1 note: dentofacial anomalies [including malocclusion] (M26.-) and syphilitic saddle nose (A50.5).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
