Patient presents with complaints consistent with potential hepatocellular carcinoma (HCC), primary liver cancer.  Symptoms include fatigue, abdominal pain localized to the right upper quadrant, unintended weight loss, and decreased appetite.  Physical examination reveals hepatomegaly and palpable liver mass.  Pertinent laboratory findings demonstrate elevated alpha-fetoprotein (AFP) levels, abnormal liver function tests (LFTs) including increased AST (aspartate aminotransferase) and ALT (alanine aminotransferase), and elevated bilirubin.  Imaging studies, including abdominal ultrasound, CT scan of the abdomen with contrast, and MRI of the liver, were ordered to assess the extent of the liver lesion and rule out other differential diagnoses such as cirrhosis, hepatitis, and metastatic liver disease.  Preliminary imaging findings suggest a solitary liver mass with characteristics suspicious for HCC.  Liver biopsy is scheduled to confirm the diagnosis and determine the histologic grade of the tumor.  The patient's medical history includes chronic hepatitis B infection, a significant risk factor for liver cancer.  Based on the clinical presentation, laboratory results, and imaging findings, the preliminary diagnosis is liver cancer (HCC).  Further evaluation, including biopsy results, will guide treatment planning, which may involve surgical resection, liver transplantation, chemotherapy, radiation therapy, targeted therapy, or palliative care depending on the stage and extent of the disease.  Patient education regarding liver cancer prognosis, treatment options, and potential complications was provided.  Follow-up appointments were scheduled to discuss biopsy results and finalize the treatment plan.  ICD-10 code C22.0 (malignant neoplasm of liver, unspecified) is provisionally assigned, pending histopathological confirmation.  CPT codes for the diagnostic procedures performed will be documented accordingly for medical billing and coding purposes.
