M24.076Loose body in unspecified toe joint(s)

M24.076 is the ICD-10-CM diagnosis code for Loose body in unspecified toe joint(s). It belongs to category M24 (other specific joint derangements), block M20-M25 (other joint disorders) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within M24.07, choose M24.076 (unspecified toe joint(s)) only when documentation doesn't support a more specific option: right ankle (M24.071), left ankle (M24.072), unspecified ankle (M24.073), right toe joint(s) (M24.074) and left toe joint(s) (M24.075).

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 564 (Other Musculoskeletal System and Connective Tissue Diagnoses with MCC, relative weight 1.4908), DRG 565 (Other Musculoskeletal System and Connective Tissue Diagnoses with CC, relative weight 0.9783) and DRG 566 (Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCC, relative weight 0.7378), 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.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2026 (title revised).

Before ICD-10, this condition was coded in ICD-9-CM as 718.17 (Loose body in joint, ankle and foot).
