About coding Guerin-Stern syndrome
The ICD-10-CM code for Guerin-Stern syndrome is Q74.3 (Arthrogryposis multiplex congenita).
Within Q74 (other congenital malformations of limb(s)), Q74.3 is specifically for Arthrogryposis multiplex congenita. Related codes cover other congenital malformations of upper limb(s), including shoulder girdle (Q74.0), congenital malformation of knee (Q74.1), other congenital malformations of lower limb(s), including pelvic girdle (Q74.2), other specified congenital malformations of limb(s) (Q74.8) and unspecified congenital malformation of limb(s) (Q74.9).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
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.
