Prоcedure: Permаnent pаcemаker implantatiоn Indicatiоn for the procedure: Sick sinus syndrome with decreased mentation and confusion Description of the procedure: After a detailed description of the procedure, indications, and potential risks of permanent pacemaker implantation was given to the patient as well as the patient's daughter, informed consent was obtained. The patient was transferred to the cardiac catheterization lab. A left subclavian area was prepared and draped in the usual sterile manner, and the left subclavian vein was accessed by Seldinger technique. A guidewire was placed. The left subclavian vein was accessed, and a separate guidewire was also placed. Following this, a deep subcutaneous pacemaker pocket was created using the blunt dissection technique without any excessive bleeding. Following this, a French-7 introducer sheath was advanced over the guidewire, and the guidewire was removed. A Medtronic bipolar endocardial lead, model #5054 and serial #LEH025605V, was advanced under fluoroscopic guidance, and the tip of the pacemaker lead was positioned in the right ventricular apex. Following this, the French-9.5 introducer sheath was advanced over a separate guidewire under fluoroscopic guidance, and the guidewire was removed. Through this sheath, a bipolar atrial screw-in lead by Medtronic, model #4568, was selected. It was positioned in the right atrial appendage, and the lead was screwed in. Following this, the stimulation thresholds were obtained for the atrial lead. The amplitude was millivolts (mv) of resistance of 549 ohms, with pulse rate of 0.5 ms. Following the ventricular stimulation, threshold perimeters were obtained, including R-wave entry of 4.6 mv with resistance of 1,427 ohms, with a pulse wave of 0.5 ms. Minimum-stimulation threshold voltage was 0.4 volt for the ventricular lead, and minimal-stimulation voltage was 2 volts for the atrial lead. Select the appropriate ICD-10-CM and CPT code(s):

Specimen site: Gаstric biоpsy Grоss descriptiоn: Gаstric biopsy: Received in formаlin, the specimen consists of two fragments of gray-brown mucosa, each measuring approximately 0.3 centimeter in diameter. Totally submitted for routine and special stains and additional levels. Microscopic description: Sections show benign-appearing gastric mucosa with acute and chronic inflammatory cells within the lamina propria. The surface and pit-lining epithelium are also infiltrated with neutrophils. There is no dysplasia or malignancy. Special stains for H. pylori are positive. Final diagnosis: Gastric biopsy: Chronic active gastritis. Warthin-Starry stain positive for H. pylori. Negative for intestinal metaplasia, dysplasia, or malignancy.
