Chapter 21: Symptoms, Signs or Clinical Findings, Not Elsewhere Classified
ICD-11 to ICD-10 crosswalk mappings for codes MA00-MH2Z
371 ICD-11 codes in this chapter have ICD-10 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 when a workup is still in progress.
