About coding familial chondrocalcinosis
The ICD-10-CM code for familial chondrocalcinosis is M11.10 (Familial chondrocalcinosis, unspecified site). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M11.10.
Within M11.1, choose M11.10 (unspecified site) only when documentation doesn't support a more specific option: shoulder (M11.11), elbow (M11.12), wrist (M11.13), hand (M11.14), hip (M11.15), knee (M11.16), ankle and foot (M11.17), vertebrae (M11.18) and 1 more.
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 553 (Bone Diseases and Arthropathies with MCC, relative weight 1.2494) and DRG 554 (Bone Diseases and Arthropathies without MCC, relative weight 0.8331), 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.
