ICD-10-CM Code For Congenital Malformations Of Spine And Bony Thorax: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group Q76 includes congenital malformations of the spine and bony thorax such as vertebral segmentation anomalies, fused vertebrae, and chest wall deformities present at birth. These ICD-10-CM diagnosis codes are used to document congenital structural abnormalities that can affect skeletal integrity, respiratory mechanics, or neurologic involvement and to capture severity, location, and related complications. Accurate coding within the ICD-10-CM Q76 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

ICD-10-CM Q76: Congenital Malformations Of Spine And Bony Thorax Overview

This code group captures congenital malformations affecting the spinal column and bony structures of the thorax, including vertebral anomalies and chest wall deformities present at birth. These conditions target the musculoskeletal system and may impact respiratory function, posture, or neurological structures. Accurate coding ensures clinical detail is preserved and supports appropriate reimbursement and care tracking.

When to Use

Use codes from this group when documenting congenital structural abnormalities of the spine or bony thorax identified at birth or on subsequent evaluation that are the focus of care or affect treatment decisions. Assign the most specific code available to capture the type and location of the malformation and any documented complications or associated findings.

Typical Clinical Scenarios

A newborn is noted at delivery to have a short, webbed neck and widely spaced, fused cervical vertebrae on neonatal exam and plain radiographs, with limited neck mobility and concern for associated airway or feeding issues. The infant is referred for genetic evaluation and orthopedics for assessment of congenital vertebral fusion; a diagnosis from this group is assigned to capture congenital anomalies of the cervical spine such as block vertebrae. Typical codes: Q76.1, Q76.0
An adolescent presents to outpatient orthopedics for chronic back pain and a visible thoracic cage deformity; imaging demonstrates multiple rib and sternum malformations with scoliosis present since early childhood that has progressed and affects pulmonary function. The clinic documents a congenital malformation of the bony thorax as the underlying cause of the chest wall deformity and plans ongoing monitoring and possible surgical correction, so a code from this group is used to report the congenital chest wall/bony thorax anomaly. Typical codes: Q76.5, Q76.8
An adult with a history of childhood congenital vertebral anomalies is admitted for evaluation of new neurologic symptoms after minor trauma; imaging reveals congenital segmentation anomalies of the lumbar spine contributing to instability and compression of neural elements, complicating the acute presentation and surgical planning. The congenital spinal malformation is coded as an important comorbidity affecting management of the acute injury. Typical codes: Q76.2, Q76.9}
