M43.5X — Other recurrent vertebral dislocation
M43.5X is a non-billable header ICD-10-CM code for other recurrent vertebral dislocation. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 inherited from the categories above M43.5X
These are not written on M43.5X, but they bind it: a note on a category applies to every code beneath it. Billing M43.5X with anything listed here is a denial.
Written on M43 — Other deforming dorsopathies
- congenital spondylolysis and spondylolisthesis (Q76.2)
- hemivertebra (Q76.3-Q76.4)
- Klippel-Feil syndrome (Q76.1)
- lumbarization and sacralization (Q76.4)
- platyspondylisis (Q76.4)
- spina bifida occulta (Q76.0)
- spinal curvature in osteoporosis (M80.-)
- spinal curvature in Paget's disease of bone [osteitis deformans] (M88.-)
Other codes that can never be billed with M43.5X
These codes carry an Excludes1 note pointing at M43.5X. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M43.5X alone.
- M47.1Other spondylosis with myelopathy
Risk adjustment
M43.5X does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
M43.5X has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Questions about M43.5X
- Is M43.5X a billable ICD-10-CM code?
- No. M43.5X is a non-billable header code. Code to a higher level of specificity using one of its child codes.
- Where does M43.5X sit in the tabular list?
- Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Deforming dorsopathies (M40-M43).
- What cannot be coded together with M43.5X?
- M43.5X carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above M43.5X (M43.5, M43) and apply to it just the same.
