    ICD-10-CM Code For Complications Of Bariatric Procedures: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group K95 includes diagnoses for complications resulting from bariatric surgical procedures, such as anastomotic leaks, strictures, obstructions, and other post‑operative digestive system issues. These ICD-10-CM diagnosis codes are used to document postoperative complications, capturing severity, affected anatomical sites, and clinical complexity relevant to management of bariatric patients. Accurate coding within the ICD-10-CM K95 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    Typical Clinical Scenarios

    • A middle-aged patient presents to the emergency department with sudden onset severe abdominal pain, nausea, vomiting, and low-grade fever two weeks after laparoscopic Roux-en-Y gastric bypass. Imaging shows an anastomotic leak with localized peritonitis related to the recent bariatric surgery; a complication of the procedure is documented and coded because it is the direct cause of the acute presentation. Typical codes: K95.01.
    • A patient seen in a bariatric surgery clinic months after sleeve gastrectomy reports chronic dysphagia, reflux, and progressive weight loss; endoscopy reveals significant anastomotic stricture and chronic stenosis at the surgical site requiring dilation. The ongoing postsurgical structural complication is recorded to explain the chronic symptoms and need for repeated interventions. Typical codes: K95.09, K95.89.
    • An outpatient with a history of prior bariatric surgery presents for management of chronic malabsorption and micronutrient deficiencies (iron deficiency anemia and vitamin B12 deficiency) attributed to altered anatomy and absorption following the procedure. The chronic nutritional complications related to the prior bariatric operation are captured with a code from this group to document the causal relationship. Typical codes: K95.81, K95.89.
