About coding Ganglion)
The ICD-10-CM code for Ganglion) is M67.40 (Ganglion, unspecified site). The official index lists 14 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on M67.40.
Within M67.4, choose M67.40 (unspecified site) only when documentation doesn't support a more specific option: shoulder (M67.41), elbow (M67.42), wrist (M67.43), hand (M67.44), hip (M67.45), knee (M67.46), ankle and foot (M67.47), other site (M67.48) 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 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.
