Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Lumbago due to displacement of intervertebral disc

Excludes2 inherited from the categories above M51.2

Also inherited, and the opposite of Excludes1: these conditions are not part of M51.2, but a patient can have both, so you may code both.

Written on M51 — Thoracic, thoracolumbar, and lumbosacral intervertebral disc disorders

cervical and cervicothoracic disc disorders (M50.-)
sacral and sacrococcygeal disorders (M53.3)

Other codes that can never be billed with M51.2

These codes carry an Excludes1 note pointing at M51.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M51.2 alone.

Risk adjustment

M51.2 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.
