Q76.49Other congenital malformations of spine, not associated with scoliosis

Q76.49 is the ICD-10-CM diagnosis code for other congenital malformations of spine, not associated with scoliosis. It belongs to category Q76 (congenital malformations of spine and bony thorax), block Q65-Q79 (congenital malformations and deformations of the musculoskeletal system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within Q76.4, choose Q76.49 (Other congenital malformations of spine, not associated with scoliosis) only when documentation doesn't support a more specific option: congenital kyphosis (Q76.41) and congenital lordosis (Q76.42).

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 is exempt from present-on-admission (POA) reporting, so no POA indicator is required.

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 756.13 (absence of vertebra, congenital), 756.14 (Hemivertebra), 756.15 (fusion of spine (vertebra), congenital) and 1 more.
