Oth deforming dorsopathies, occipito-atlanto-axial region

This code signifies a non-specific, structural deformity of the upper cervical spine, specifically involving the occiput, atlas (C1), and axis (C2). It encompasses various congenital or acquired conditions that cause abnormal shape or alignment in this critical region, leading to potential neurological or mechanical symptoms.

Apply this code when documentation clearly indicates a deforming dorsopathy of the occipito-atlanto-axial region that doesn't fit a more specific ICD-10-CM code. This may include conditions like Klippel-Feil syndrome affecting this specific area, atlanto-occipital assimilation, or other congenital malformations not otherwise classified. Documentation should specify the anatomical region and the deforming nature of the condition.

• Ensure the documentation explicitly states the "occipito-atlanto-axial region" to justify this specific anatomical site.
• Always search for a more specific code first; this is a "specified, not elsewhere classified" option.
• Review imaging reports (X-ray, MRI, CT) for definitive evidence of the structural deformity.
