About M43.5
M43.5 is the ICD-10-CM diagnosis code for other recurrent vertebral dislocation. It belongs to category M43 (other deforming dorsopathies), block M40-M43 (deforming dorsopathies) and chapter 13 (diseases of the musculoskeletal system and connective tissue). It is a header code, so it can't be reported by itself; one of its 1 subcodes must be used instead.
Within M43, choose M43.5 (Other recurrent vertebral dislocation) only when documentation doesn't support a more specific option: Spondylolysis (M43.0), spondylolisthesis (M43.1), fusion of spine (M43.2), recurrent atlantoaxial dislocation with myelopathy (M43.3), other recurrent atlantoaxial dislocation (M43.4), torticollis (M43.6), other specified deforming dorsopathies (M43.8) and deforming dorsopathy, unspecified (M43.9).
To report this condition, pick the subcode that matches the documentation: M43.5X (dislocation).
Don't report M43.5 together with the conditions in its Excludes1 note: biomechanical lesions NEC (M99.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
