G89.2 — Chronic pain, not elsewhere classified

Non-billable headerICD-10-CM

G89.2 is a non-billable header ICD-10-CM code for chronic pain, not elsewhere classified. 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-)
  • central pain syndrome (G89.0)
  • chronic pain syndrome (G89.4)
  • complex regional pain syndrome II, lower limb (G57.7-)
  • complex regional pain syndrome II, upper limb (G56.4-)
  • neoplasm related chronic pain (G89.3)
  • reflex sympathetic dystrophy (G90.5-)

Excludes1 inherited from the categories above G89.2

These are not written on G89.2, but they bind it: a note on a category applies to every code beneath it. Billing G89.2 with anything listed here is a denial.

Written on G89 — Pain, not elsewhere classified

  • generalized pain NOS (R52)
  • pain disorders exclusively related to psychological factors (F45.41)
  • pain NOS (R52)

Excludes2 inherited from the categories above G89.2

Also inherited, and the opposite of Excludes1: these conditions are not part of G89.2, but a patient can have both, so you may code both.

Written on G89 — Pain, not elsewhere classified

Other codes that can never be billed with G89.2

These codes carry an Excludes1 note pointing at G89.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading G89.2 alone.

Risk adjustment

G89.2 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.

Code history

G89.2 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
