M89.0Algoneurodystrophy

Non-billable headerICD-10-CM

M89.0 is a non-billable header ICD-10-CM code for algoneurodystrophy. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • causalgia, lower limb (G57.7-)
  • causalgia, upper limb (G56.4-)
  • complex regional pain syndrome II, lower limb (G57.7-)
  • complex regional pain syndrome II, upper limb (G56.4-)
  • reflex sympathetic dystrophy (G90.5-)

Inclusion terms

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

  • Shoulder-hand syndrome
  • Sudeck's atrophy

Other codes that can never be billed with M89.0

These codes carry an Excludes1 note pointing at M89.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M89.0 alone.

  • M81Osteoporosis without current pathological fracture
  • M81.6Localized osteoporosis [Lequesne]

Risk adjustment

M89.0 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 to one of these instead M89.0

10 child codes. Green means billable.
