About coding Hemarthrosis
The ICD-10-CM code for Hemarthrosis is M25.00 (Hemarthrosis, 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 M25.00.
Within M25.0, choose M25.00 (unspecified joint) only when documentation doesn't support a more specific option: shoulder (M25.01), elbow (M25.02), wrist (M25.03), hand (M25.04), hip (M25.05), knee (M25.06), ankle and foot (M25.07) and other specified site (M25.08).
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 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.
