ICD-10 Code K95.81 – Infection due to other bariatric procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K95.81 – Infection due to other bariatric procedure
What it is
K95.81 identifies an infection that occurs as a complication of a bariatric procedure other than the specifically listed ones. Use it when documentation links the infection directly to the prior weight-loss surgery.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may describe local redness, drainage, pain, fever, or other signs of postoperative infection involving the surgical site or related area.
When to use this code
Use this code when the provider documents an infection caused by, or due to, a bariatric procedure and the procedure is not one of the more specific coded types. It applies to postoperative complications tied to the surgery. If the note does not clearly connect the infection to the bariatric procedure, check documentation.
Do not use for
Do not use this code for routine postoperative pain, swelling, or wound concerns without documented infection. Also avoid it when a more specific bariatric-complication code is documented.
Coding tip
Confirm both the infection and the causal link to the bariatric procedure in the provider’s note before assigning K95.81.
