ICD-9-CM to ICD-10-CM CODE CONVERSION

Direct conversions between the ICD-9-CM codes used in this analysis to ICD-10-CM codes is difficult due to the greatly expanded diagnosis codes in ICD-10-CM. For example, converting the six codes included in the Lumbar/Low Back Back Disorders group returns only six general or unspecified codes related to the spondylopathies whereas, in reality, there are five major classifications (M45, M46, M47, M48, M49) each of which is broken down into specific conditions that are further broken down by site. For example, using only the M45 and M46 codes (shown below) there are 80 new codes.

     M45 Ankylosing spondylitis
        M45.0 Ankylosing spondylitis of multiple sites in spine
        M45.1 Ankylosing spondylitis of occipito-atlanto-axial region
        M45.2 Ankylosing spondylitis of cervical region
        M45.3 Ankylosing spondylitis of cervicothoracic region
        M45.4 Ankylosing spondylitis of thoracic region
        M45.5 Ankylosing spondylitis of thoracolumbar region
        M45.6 Ankylosing spondylitis lumbar region
        M45.7 Ankylosing spondylitis of lumbosacral region
        M45.8 Ankylosing spondylitis sacral and sacrococcygeal region
        M45.9 Ankylosing spondylitis of unspecified sites in spine

            M46.81 …… occipito-atlanto-axial region
            M46.82 …… cervical region

            M46.84 …… thoracic region
            M46.85 …… thoracolumbar region
            M46.86 …… lumbar region
            M46.87 …… lumbosacral region
            M46.88 …… sacral and sacrococcygeal region

            M46.98 …… sacral and sacrococcygeal region
            M46.99 …… multiple sites in spine

and so on. Future analysis for BMUS will require identification of new categories for analysis of spine low back and neck diagnosis.

Conversion of the spine procedure codes was made and can be viewed by clicking HERE. Again, the number of codes is greatly expanded, with more than 650 new codes representing the 25 spine procedure codes analyzed in this Fourth Edition of The Burden Of Musculoskeletal Diseases in the United States.
