ICD-10 code for congenital bowleg

The ICD-10-CM code for congenital bowleg is Q68.5 (Congenital bowing of long bones of leg, unspecified).

Within Q68, choose Q68.5 (Congenital bowing of long bones of leg, unspecified) only when documentation doesn't support a more specific option: congenital deformity of sternocleidomastoid muscle (Q68.0), congenital deformity of finger(s) and hand (Q68.1), congenital deformity of knee (Q68.2), congenital bowing of femur (Q68.3), congenital bowing of tibia and fibula (Q68.4), Discoid meniscus (Q68.6) and other specified congenital musculoskeletal deformities (Q68.8).

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.
