About M42.06

M42.06 is the ICD-10-CM diagnosis code for juvenile osteochondrosis of spine, lumbar region. It belongs to category M42 (spinal osteochondrosis), block M40-M43 (deforming dorsopathies) 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 M42.0 (juvenile osteochondrosis of spine), M42.06 is specifically for juvenile osteochondrosis of spine, lumbar region. Related codes cover site unspecified (M42.00), occipito-atlanto-axial region (M42.01), cervical region (M42.02), cervicothoracic region (M42.03), thoracic region (M42.04), thoracolumbar region (M42.05), lumbosacral region (M42.07), sacral and sacrococcygeal region (M42.08) 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 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 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.

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 732.0 (juvenile osteochondrosis of spine).
