About coding talipes
The ICD-10-CM code for talipes is Q66.89 (Other specified congenital deformities of feet). The official index lists 14 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Q66.89.
Within Q66.8, choose Q66.89 (Other specified congenital deformities of feet) only when documentation doesn't support a more specific option: congenital vertical talus deformity, unspecified foot (Q66.80), congenital vertical talus deformity, right foot (Q66.81) and congenital vertical talus deformity, left foot (Q66.82).
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.
