About coding Osteophyte
The ICD-10-CM code for Osteophyte is M25.70 (Osteophyte, unspecified joint). The official index lists 10 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M25.70.
Within M25.7, choose M25.70 (unspecified joint) only when documentation doesn't support a more specific option: shoulder (M25.71), elbow (M25.72), wrist (M25.73), hand (M25.74), hip (M25.75), knee (M25.76), ankle and foot (M25.77) and vertebrae (M25.78).
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 557 (Tendonitis, Myositis and Bursitis with MCC, relative weight 1.489) and DRG 558 (Tendonitis, Myositis and Bursitis without MCC, relative weight 0.8875), 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.
