About coding patella biparta
The ICD-10-CM code for patella biparta is Q74.1 (Congenital malformation of knee).
Within Q74 (other congenital malformations of limb(s)), Q74.1 is specifically for congenital malformation of knee. Related codes cover other congenital malformations of upper limb(s), including shoulder girdle (Q74.0), other congenital malformations of lower limb(s), including pelvic girdle (Q74.2), 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 Q74.1 together with the conditions in its Excludes1 note: congenital dislocation of knee (Q68.2), congenital genu recurvatum (Q68.2) and nail patella syndrome (Q87.2).
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 Q74.1)
