About M47.014

M47.014 is the ICD-10-CM diagnosis code for anterior spinal artery compression syndromes, thoracic region. It belongs to category M47 (spondylosis), block M45-M49 (spondylopathies) 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 M47.01 (anterior spinal artery compression syndromes), M47.014 is specifically for anterior spinal artery compression syndromes, thoracic region. Related codes cover occipito-atlanto-axial region (M47.011), cervical region (M47.012), cervicothoracic region (M47.013), thoracolumbar region (M47.015), lumbar region (M47.016) and site unspecified (M47.019).

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

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 721.1 (cervical spondylosis with myelopathy).
