About coding ankle joint anomaly
The ICD-10-CM code for ankle joint anomaly is Q74.2 (Other congenital malformations of lower limb(s), including pelvic girdle).
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.
Don't confuse with (Excludes1 for Q74.2)
- anteversion of femur (neck) (Q65.89)
