About D49.2

D49.2 is the ICD-10-CM diagnosis code for neoplasm of unspecified behavior of bone, soft tissue, and skin. It belongs to category D49 (neoplasms of unspecified behavior), block D49 (neoplasms of unspecified behavior) and chapter 2 (neoplasms). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within D49 (neoplasms of unspecified behavior), D49.2 is specifically for neoplasm of unspecified behavior of bone, soft tissue, and skin. Related codes cover digestive system (D49.0), respiratory system (D49.1), breast (D49.3), bladder (D49.4), other genitourinary organs (D49.5), brain (D49.6), endocrine glands and other parts of nervous system (D49.7), other specified sites (D49.8) and 1 more.

Don't report D49.2 together with the conditions in its Excludes1 note: neoplasm of unspecified behavior of anal canal (D49.0), neoplasm of unspecified behavior of anus NOS (D49.0), neoplasm of unspecified behavior of bone marrow (D49.89), neoplasm of unspecified behavior of cartilage of larynx (D49.1) and 4 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 456 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection with MCC, relative weight 7.6244), DRG 457 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection with CC, relative weight 5.3668), DRG 458 (Spinal Fusion Except Cervical with Spinal Curvature, Malignancy, or Infection without CC/MCC, relative weight 4.0388), 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 hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 239.2 (neoplasm of unspecified nature of bone, soft tissue, and skin).
