About Q87.83

Q87.83 is the ICD-10-CM diagnosis code for Bardet-Biedl syndrome. It belongs to category Q87 (other specified congenital malformation syndromes affecting multiple systems), block Q80-Q89 (other congenital malformations) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q87.8 (other specified congenital malformation syndromes, not elsewhere classified), Q87.83 is specifically for Bardet-Biedl syndrome. Related codes cover Alport syndrome (Q87.81), arterial tortuosity syndrome (Q87.82), Laurence-Moon syndrome (Q87.84), MED13L syndrome (Q87.85), Kleefstra syndrome (Q87.86), Hao-Fountain Syndrome (Q87.87), CTNNB1 syndrome (Q87.88) and other specified congenital malformation syndromes, not elsewhere classified (Q87.89).

Use an additional code(s) to identify all associated manifestations.

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.

It is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

It was added in FY2024, effective October 1, 2023.
