Symptoms and signs involving the digestive system and abdomen (R10-R19)

ICD-10 codes R10-R19 cover a wide range of symptoms and signs related to the digestive system and abdomen, including various types of abdominal pain, nausea, vomiting, and abnormal bowel or abdominal findings. These codes are used to classify patient complaints and signs when a precise diagnosis may not be established yet.

This range includes codes for detailed locations and types of abdominal pain, such as acute abdomen (R10.0), upper quadrant pain, pelvic pain (R10.2), and generalized abdominal tenderness (R10.817). It also encompasses nausea and vomiting codes (R11), covering symptoms from simple nausea through specific types like bilious vomiting (R11.14) or cyclical vomiting syndrome (R11.15). The chapter further includes swallowing difficulties labeled aphagia and dysphagia (R13), with precise subcategories to specify phases of swallowing impairment. Other symptoms in this range include flatulence and abdominal distension (R14), fecal incontinence (R15), and signs of organ enlargement like hepatomegaly and splenomegaly (R16). Additionally, codes covering jaundice (R17) and ascites (R18) help capture abnormal clinical findings related to fluid accumulation. Finally, R19 codes describe a variety of other digestive and abdominal signs such as masses, abnormal bowel sounds, rigidity, and changes in bowel habits.

Using synonyms such as "acute abdominal pain" for R10.0, "rebound abdominal tenderness" for R10.82, or "flatulence" for R14.3 aids coders in accurately selecting codes based on symptom descriptions. This comprehensive collection assists healthcare professionals in documenting presenting symptoms and physical findings that guide further diagnosis and treatment of digestive and abdominal conditions.

Instructional Notations

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
