R94.5 is the authoritative medical code for Abnormal results of liver function studies. This classification is used in medical billing and clinical recording to specify the clinical criteria for abnormal results of liver function studies (ICD-10-CM R94.5), ensuring healthcare documentation aligns with 2026 federal coding standards.
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Official Registry Overview & Definition
Abnormal results of liver function studies is a billable ICD-10-CM diagnosis code R94.5. Includes: abnormal results of radionuclide radioisotope uptake studies; abnormal results of scintigraphy; nonspecific abnormal findings on diagnostic imaging by computerized axial tomography CAT scan; nonspecific abnormal findings on diagnostic imaging by magnetic resonance imaging MRINMR; nonspecific abnormal findings on diagnostic imaging by positron emission tomography PET scan; nonspecific abnormal findings on diagnostic imaging by thermography; nonspecific abnormal findings on diagnostic imaging by ultrasound echogram; nonspecific abnormal findings on diagnostic imaging by X-ray examination. Excludes1 (not coded here): abnormal findings on antenatal screening of mother O28.-; diagnostic abnormal findings classified elsewhere - see Alphabetical Index.
