ICD-10 Code K45 – Other abdominal hernia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K45 – Other abdominal hernia
What it is
K45 identifies an abdominal hernia that does not fit a more specific category. It means part of tissue or an organ protrudes through a weakness in the abdominal wall.
Clinical signs
Typical findings include a visible or palpable bulge, discomfort, or pain that may worsen with coughing, lifting, or straining. Clinical features vary; refer to documentation.
When to use this code
Use K45 when the record clearly documents an abdominal hernia but does not specify a more exact type such as inguinal, femoral, umbilical, or incisional. It is appropriate when the provider describes the hernia as other abdominal hernia or gives an equivalent nonspecific diagnosis. Check documentation if the site or type is unclear.
Do not use for
Do not assign K45 when the hernia type is documented more specifically elsewhere in ICD-10-CM. Do not use it for hiatal hernia or other nonabdominal hernias.
Coding tip
Code the most specific hernia type documented; use K45 only when the record supports an abdominal hernia but not a more precise category.
