About D16.6
D16.6 is the ICD-10-CM diagnosis code for benign neoplasm of vertebral column. It belongs to category D16 (benign neoplasm of bone and articular cartilage), block D10-D36 (benign neoplasms, except benign neuroendocrine tumors) 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 D16 (benign neoplasm of bone and articular cartilage), D16.6 is specifically for benign neoplasm of vertebral column. Related codes cover scapula and long bones of upper limb (D16.0), short bones of upper limb (D16.1), long bones of lower limb (D16.2), short bones of lower limb (D16.3), bones of skull and face (D16.4), lower jaw bone (D16.5), ribs, sternum and clavicle (D16.7), pelvic bones, sacrum and coccyx (D16.8) and 1 more.
Don't report D16.6 together with the conditions in its Excludes1 note: benign neoplasm of sacrum and coccyx (D16.8).
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 213.2 (benign neoplasm of vertebral column, excluding sacrum and coccyx).
