About M40.293

M40.293 is the ICD-10-CM diagnosis code for other kyphosis, cervicothoracic region. It belongs to category M40 (kyphosis and lordosis), 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 M40.29 (other kyphosis), M40.293 is specifically for other kyphosis, cervicothoracic region. Related codes cover cervical region (M40.292), thoracic region (M40.294), thoracolumbar region (M40.295) and site unspecified (M40.299).

Code first: underlying disease.

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 551 (Medical Back Problems with MCC, relative weight 1.6358) and DRG 552 (Medical Back Problems without MCC, relative weight 0.9584), 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 737.19 (other kyphosis (acquired)).
