Patient presents with complaints consistent with renal colic, including sudden onset of severe flank pain radiating to the groin, hematuria, nausea, and vomiting.  Pain described as sharp, intermittent, and debilitating.  Differential diagnosis includes nephrolithiasis, ureterolithiasis, pyelonephritis, urinary tract infection, appendicitis, and other abdominal emergencies.  Physical examination reveals costovertebral angle tenderness.  Urinalysis demonstrates microscopic hematuria.  Kidney stone symptoms, kidney stone pain, and kidney stone treatment were discussed with the patient.  Imaging studies, including a non-contrast CT scan of the abdomen and pelvis, were ordered to confirm the diagnosis of kidney stones and assess stone size, location (e.g., renal pelvis, ureter), and degree of obstruction.  Patient history includes hypertension, controlled with medication.  No known allergies.  Current medications include lisinopril.  The patient is being managed conservatively with pain medication (e.g., ibuprofen, ketorolac) for renal colic pain management, increased fluid intake to promote stone passage, and antiemetics to address nausea.  Patient education provided on kidney stone prevention strategies, including dietary modifications and hydration.  Follow-up scheduled to monitor stone passage and assess need for further intervention, such as extracorporeal shock wave lithotripsy (ESWL), ureteroscopy, or percutaneous nephrolithotomy (PCNL), if the stone does not pass spontaneously.  Medical coding will reflect the specific diagnosis, procedures performed, and level of service provided.  ICD-10 codes for kidney stones (e.g., N20.0, N20.1) and CPT codes for diagnostic and treatment procedures will be documented appropriately for billing purposes.
