Chapter 18: Symptoms, Signs and Abnormal Clinical and Laboratory Findings
ICD-10 to ICD-11 crosswalk mappings for codes R00-R99
367 ICD-10 codes in this chapter have ICD-11 crosswalk mappings from the WHO.
Covers symptoms and signs that do not yet have a definitive diagnosis, including chest pain, abdominal pain, fever, cough, headache, fatigue, and abnormal lab results. These codes are commonly used in emergency and outpatient settings when a workup is still in progress. Chest pain (R07) and abdominal pain (R10) are among the top reasons for ER visits.
