ICD-10 code for Megalodactylia

The ICD-10-CM code for Megalodactylia is Q74.0 (Other congenital malformations of upper limb(s), including shoulder girdle). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on Q74.0.

Within Q74, choose Q74.0 (Other congenital malformations of upper limb(s), including shoulder girdle) only when documentation doesn't support a more specific option: congenital malformation of knee (Q74.1), 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).

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.
