Billable codes in this category
Each of the codes below is billable. Choose the one that most accurately describes the patient's diagnosis.
Vertebral subluxation complex localized to the head region, encompassing the occiput and occipitocervical junction, classified as a biomechanical lesion under ICD-10-CM Chapter 13.
M99.11 identifies a vertebral subluxation complex localized to the cervical region — a biomechanical lesion characterized by altered segmental motion and positional integrity of the cervical spine, classified under the ICD-10-CM category for biomechanical lesions not elsewhere classified.
M99.12 identifies a vertebral subluxation complex localized to the thoracic spine — a biomechanical lesion classified under M99 (Biomechanical lesions, not elsewhere classified) rather than under injury or traumatic dislocation codes.
Vertebral subluxation complex localized to the lumbar spine, representing aberrant segmental motion or positional fault of one or more lumbar vertebrae as a biomechanical lesion.
Vertebral subluxation complex localized to the sacral region, classified under biomechanical lesions not elsewhere classified (M99 category).
Vertebral subluxation complex localized to the pelvic region, classified under biomechanical lesions not elsewhere classified (M99 category).
M99.16 identifies a subluxation complex of a vertebral nature localized to the lower extremity, classified under biomechanical lesions not elsewhere classified in Chapter 13 of ICD-10-CM.
Biomechanical subluxation complex of the upper extremity, classified as a vertebral subluxation affecting structures of the shoulder girdle or related upper limb region, including the acromioclavicular and sternoclavicular joints.
M99.18 identifies a subluxation complex of vertebral origin specifically affecting the rib cage, encompassing costochondral, costovertebral, sternochondral, and rib cage articulation dysfunctions classified as biomechanical lesions.
Vertebral subluxation complex affecting the abdominal region or any anatomical region not captured by the more specific M99.10–M99.18 site codes.
