ICD-10 Code K82.9 – Disease of gallbladder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K82.9 – Disease of gallbladder, unspecified
What it is
K82.9 is used when the record documents a gallbladder disorder but does not name a more specific condition. It captures nonspecific gallbladder disease when the exact diagnosis is not stated.
Clinical signs
Clinical features vary; refer to documentation. Gallbladder disease may present with right upper quadrant pain, nausea, vomiting, or findings suggestive of biliary disease, but the chart must support the nonspecific diagnosis.
When to use this code
Use K82.9 when the provider identifies gallbladder disease without further detail, such as an unspecified gallbladder disorder in the assessment. It is appropriate when the note lacks a clearer diagnosis after review of the available record.
Choose this code only when you cannot code a more specific gallbladder condition from the documentation. If imaging, operative notes, or the assessment names a defined disorder, code that diagnosis instead.
Do not use for
Do not use K82.9 when the chart specifies cholelithiasis, cholecystitis, gallbladder polyp, or another defined gallbladder condition. Check documentation if the term “gallbladder disease” appears alongside a more exact diagnosis.
Coding tip
Query or review the record for a specific gallbladder diagnosis before defaulting to K82.9.
