R10.824Left lower quadrant rebound abdominal tenderness

Billable / specific codeICD-10-CMleft

R10.824 is a billable, specific ICD-10-CM code for left lower quadrant rebound abdominal tenderness. It is valid for submission on a claim.

Excludes1 inherited from the categories above R10.824

These are not written on R10.824, but they bind it: a note on a category applies to every code beneath it. Billing R10.824 with anything listed here is a denial.

Written on R10 Abdominal and pelvic pain

  • renal colic (N23)

Excludes2 inherited from the categories above R10.824

Also inherited, and the opposite of Excludes1: these conditions are not part of R10.824, but a patient can have both, so you may code both.

Written on R10.82 Rebound abdominal tenderness

  • pain localized to other parts of lower abdomen (R10.3-)
  • pain localized to upper abdomen (R10.1-)

Written on R10 Abdominal and pelvic pain

  • costovertebral (angle) tenderness (R39.85)
  • dorsalgia (M54.-)
  • flatulence and related conditions (R14.-)

Other codes that can never be billed with R10.824

These codes carry an Excludes1 note pointing at R10.824. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading R10.824 alone.

  • R52Pain, unspecified

Risk adjustment

R10.824 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.

Medicare coverage

R10.824 is named in 7 Medicare coverage policies 7 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
