ICD-10 Code K95 – Complications of Bariatric Procedures (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K95 – Complications of bariatric procedures
What it is
K95 identifies complications that occur after bariatric surgery, such as gastric bypass or other weight-loss procedures. Use it when the record documents a postoperative problem tied to the bariatric procedure itself.
Clinical signs
Clinical features vary; refer to documentation. Records may describe pain, vomiting, obstruction, leakage, malabsorption, or other surgery-related complications after bariatric intervention.
When to use this code
Use K95 when the provider links the current condition to a prior bariatric procedure and documents it as a complication. It is appropriate for postoperative problems that are not simply routine follow-up or expected recovery. Check documentation for the specific complication and timing.
Do not use for
Do not use this code for routine aftercare, obesity alone, or problems unrelated to the bariatric procedure. If the chart does not clearly connect the issue to surgery, check documentation.
Coding tip
Capture the exact postoperative complication from the note, because K95 is a category code and the record should support the specific manifestation.
