2025 ICD-10-CM code K83.9

Unspecified disease of the biliary tract.

Always attempt to use a more specific K83 code if diagnostic information is available. Review the entire K80-K87 chapter for potential alternative diagnoses.

Medical necessity for further investigation into an unspecified biliary tract disease is established when a patient presents with symptoms indicative of biliary dysfunction, such as abnormal liver function tests, jaundice, and abdominal pain. Further tests are needed to rule out serious conditions and guide appropriate treatment.

The clinical responsibility for this code depends heavily on the underlying unspecified biliary tract disease.It could involve gastroenterologists, surgeons, or other specialists depending on the nature and severity of the problem.

IMPORTANT:Consider using more specific codes from the K83 range (K83.0-K83.8) if a more precise diagnosis is possible.If the condition relates to the gallbladder itself, K81 or K82 codes may be more appropriate.

In simple words: This code is used when a person has a problem with their bile ducts (tubes that carry bile from the liver), but the exact problem is not known or can't be determined.

This ICD-10-CM code classifies any disease affecting the biliary tract (the system of ducts that carry bile from the liver to the gallbladder and small intestine) where the specific condition is unknown or cannot be specified.This includes conditions not otherwise specified within the K83 code range.It is a residual category for biliary tract problems when a more precise diagnosis isn't available.

Example 1: A patient presents with abdominal pain and jaundice, but imaging studies are inconclusive regarding the specific cause.K83.9 is used as a placeholder until further investigations clarify the diagnosis., A patient undergoes an ERCP (endoscopic retrograde cholangiopancreatography) procedure, but the findings are non-specific and no identifiable cause for the patient's symptoms is discovered. K83.9 is assigned to reflect the uncertain diagnosis., A patient has elevated liver enzymes and abnormal biliary function tests, but further tests such as MRCP (magnetic resonance cholangiopancreatography) fail to pinpoint the specific biliary pathology. K83.9 is used until more information is obtained.

Detailed patient history including symptoms (abdominal pain, jaundice, fever, etc.),results of relevant laboratory tests (liver function tests, bilirubin levels),and imaging reports (ultrasound, CT scan, MRCP, ERCP).If a procedure was performed, detailed operative notes are essential.

** This is a non-specific code and should be used cautiously.Always strive for the most precise diagnosis possible.The choice between K83.9 and other K83 codes depends heavily on the available clinical information.In outpatient settings, appropriate diagnostic confidence indicators (A, G, V, or Z) should be added as per local guidelines.
