What Are the ICD-10 Codes for Abdominal Pain?

Here are all the ICD-10 codes for different forms of abdominal pain. Two quick qualifiers:

  1. You cannot record the code for renal colic alongside abdominal pain codes.
  2. Abdominal pain codes do not cover dorsalgia or flatulence and related conditions, but the codes for these conditions can be used in conjunction with abdominal pain codes.

All codes begin with R10, the general code for abdominal and pelvic pain, and then up to three numbers can be added to that code for a more specific diagnosis.

  • Abdominal and pelvic pain: R10
    • Acute abdomen: R10.0
    • Pain localized to upper abdomen: R10.1
      • Upper abdominal pain, unspecified R10.10

Guidelines on Using ICD-10 Codes for Abdominal Pain

Since the codes for abdominal pain describe symptoms and not specific diagnoses, they are mostly used when a conclusive diagnosis has not yet been determined. These codes may also be used when the abdominal pain symptom occurs alongside a diagnosis that is not typically associated with it, but the code for the main diagnosis should always be recorded first.

The “unspecified” codes should be used when information in the patient’s record isn’t sufficient to assign a more specific code. Always be as accurate as possible when recording these codes; record the highest number of characters you can based on the information given. If abdominal pain occurs in two or more places (i.e. right upper quadrant and left upper quadrant), assign a separate code for each location.

What Are ICD-10 Codes?

ICD (International Classification of Diseases) codes are a way for doctors to record diagnoses in a succinct universal language. ICD-10 codes refer to the codes from the 10th Revision of this classification system. These codes consist of three to seven characters (both letters and numbers). 

ICD-10 officially replaced ICD-9 in the US in October of 2015. This was a response to the need for doctors to record more specific and accurate diagnoses in up-to-date terms. There are five times more ICD-10 codes than there were ICD-9 codes!
