Patient presents with obstructive jaundice, characterized by hyperbilirubinemia, predominantly conjugated.  Clinical manifestations include yellowing of the skin and sclera (icterus), dark urine, and clay-colored stools.  Pruritus is also reported.  Possible etiologies under consideration include choledocholithiasis, biliary stricture, pancreatic head mass, and cholangiocarcinoma.  Differential diagnosis includes pre-hepatic causes of jaundice such as hemolysis and hepatic causes like hepatitis.  Initial laboratory evaluation reveals elevated total and direct bilirubin, elevated alkaline phosphatase, and elevated gamma-glutamyl transferase (GGT).  Liver function tests, including aspartate aminotransferase (AST) and alanine aminotransferase (ALT), may be elevated.  Abdominal ultrasound is ordered to assess biliary duct dilation and identify potential obstructing masses.  Further imaging with magnetic resonance cholangiopancreatography (MRCP) or endoscopic retrograde cholangiopancreatography (ERCP) may be indicated for definitive diagnosis and potential therapeutic intervention.  Treatment plan is dependent on the underlying cause of the obstruction and may include endoscopic or surgical removal of the obstruction, biliary stenting, or percutaneous transhepatic cholangiography (PTC) for drainage.  Patient education regarding the condition, diagnostic procedures, and treatment options was provided.  Follow-up appointment scheduled to review imaging results and determine further management.  ICD-10 code R17 is considered, with further specification based on the identified cause of obstruction.  Medical billing will reflect the diagnostic procedures and therapeutic interventions performed.
