About Q74.2

Q74.2 is the ICD-10-CM diagnosis code for other congenital malformations of lower limb(s), including pelvic girdle. It belongs to category Q74 (other congenital malformations of limb(s)), block Q65-Q79 (congenital malformations and deformations of the musculoskeletal system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 564 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, relative weight 1.4908), DRG 565 (Other Musculoskeletal System and Connective Tissue Diagnoses with CC, relative weight 0.9783) and DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 755.65 (Macrodactylia of toes) and 755.69 (other anomalies of lower limb, including pelvic girdle).
