ICD-10 code for Phocomelia

The ICD-10-CM code for Phocomelia is Q73.1 (Phocomelia, unspecified limb(s)).

Within Q73, choose Q73.1 (Phocomelia, unspecified limb(s)) only when documentation doesn't support a more specific option: congenital absence of unspecified limb(s) (Q73.0) and other reduction defects of unspecified limb(s) (Q73.8).

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.
