Collapsed vert, NEC, occipt-atlan-ax rgn, 7thG

Collapsed vertebra, not elsewhere classified, occipito-atlanto-axial region, subsequent encounter for fracture with delayed healing

AIClinical Context

Clinical Description

This code signifies a vertebral collapse in the upper cervical spine (occiput, C1, C2) that is not due to trauma, osteoporosis, or other specified causes. It specifically indicates that the patient is in a subsequent phase of care for this fracture, and the healing process is prolonged or delayed.

When to Use

Use this code for patients presenting for follow-up care of a non-traumatic, non-osteoporotic collapsed vertebra in the occipito-atlanto-axial region, where the fracture is not healing as expected. Documentation should clearly state "delayed healing" and specify the occipito-atlanto-axial region.

Coding Tips

Ensure documentation specifies "delayed healing" and the exact vertebral region (occipito-atlanto-axial).
Distinguish from initial encounters or subsequent encounters for routine healing (M48.51XA or M48.51XD).
Do not use for collapsed vertebrae due to osteoporosis (M80.-) or acute traumatic fractures (S12.-).
