About coding Chondro-osteodysplasia
The ICD-10-CM code for Chondro-osteodysplasia is E76.219 (Morquio mucopolysaccharidoses, unspecified).
Within E76.21, choose E76.219 (unspecified) only when documentation doesn't support a more specific option: A mucopolysaccharidoses (E76.210) and B mucopolysaccharidoses (E76.211).
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 642 (Inborn and Other Disorders of Metabolism, relative weight 1.3219), in MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
