G89 — Pain, not elsewhere classified

Non-billable headerICD-10-CM

G89 is a non-billable header ICD-10-CM code for 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.

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

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

  • related psychological factors associated with pain (F45.42)

Other codes that can never be billed with G89

These codes carry an Excludes1 note pointing at G89. 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 alone.

  • R52Pain, unspecified
  • G89.2Chronic pain, not elsewhere classified

Risk adjustment

G89 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 G89

5 child codes. Green means billable.
