About coding hip maldevelopment
The ICD-10-CM code for hip maldevelopment is Q74.2 (Other congenital malformations of lower limb(s), including pelvic girdle). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q74.2.
Within Q74, choose Q74.2 (Other congenital malformations of lower limb(s), including pelvic girdle) only when documentation doesn't support a more specific option: other congenital malformations of upper limb(s), including shoulder girdle (Q74.0), congenital malformation of knee (Q74.1), Arthrogryposis multiplex congenita (Q74.3), other specified congenital malformations of limb(s) (Q74.8) and unspecified congenital malformation of limb(s) (Q74.9).
Don't report Q74.2 together with the conditions in its Excludes1 note: anteversion of femur (neck) (Q65.89).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
