This resource provides information on adenomyomatosis symptoms, treatment options, and relevant healthcare documentation guidelines. Find details on the appropriate medical coding terminology for adenomyomatosis for accurate clinical records and billing. Understand the difference between adenomyomatosis and other gallbladder conditions.
Benign gallbladder wall thickening with mucosal outpouchings (Rokitansky-Aschoff sinuses).
Often asymptomatic. May cause right upper quadrant pain, nausea, or vomiting, mimicking gallstones.
Diagnosed incidentally on ultrasound or other abdominal imaging.

When to use each related code
| Description | When to use |
|---|---|
| Benign gallbladder wall thickening. | Use for localized or diffuse gallbladder wall thickening with Rokitansky-Aschoff sinuses. Exclude malignancy. |
| Cholesterolosis, benign cholesterol buildup. | Use for focal or diffuse gallbladder wall thickening due to cholesterol deposits. 'Strawberry gallbladder' appearance. |
| Gallbladder polyps, mostly benign growths. | Use for small, fixed projections from the gallbladder wall. Consider malignancy if large or rapidly growing. |
Best-practice checklist
- ✓Adenomyomatosis diagnosis: Document gallbladder wall thickening
- ✓Specify diffuse or segmental adenomyomatosis location
- ✓Note Rokitansky-Aschoff sinuses presence/absence
- ✓Document any associated cholelithiasis or polyps
- ✓Adenomyomatosis: Include ultrasound or other imaging findings
Common pitfalls to avoid
Coding adenomyomatosis requires specifying the affected organ (e.g., gallbladder). Unspecified location can lead to claim rejection.
Differentiating between diffuse and focal adenomyomatosis is crucial for accurate coding and impacts clinical documentation requirements.
Presence of gallstones with adenomyomatosis needs accurate coding. Missing codes for cholelithiasis impacts reimbursement.

Step-by-step checklist
- 1
Verify gallbladder wall thickening on imaging (ICD-10 K82.8)
- 2
Assess for Rokitansky-Aschoff sinuses (RAS) presence
- 3
Evaluate for intramural diverticula (patient safety)
- 4
Correlate imaging with symptoms: abdominal pain, nausea (SNOMED CT)
Ready-to-paste narrative
Patient presents with symptoms suggestive of gallbladder adenomyomatosis, including intermittent right upper quadrant pain, bloating, and nausea, possibly exacerbated by fatty meals. Differential diagnosis includes cholelithiasis, chronic cholecystitis, and gallbladder polyps. Physical examination revealed mild tenderness in the right upper quadrant upon palpation. Abdominal ultrasound demonstrated diffuse gallbladder wall thickening with Rokitansky-Aschoff sinuses, characteristic of adenomyomatosis. No evidence of gallstones or biliary obstruction was observed. Laboratory findings, including liver function tests, were within normal limits. The diagnosis of gallbladder adenomyomatosis was established based on the combination of clinical presentation, imaging findings, and absence of other pathology. Conservative management is recommended at this time, focusing on dietary modifications to reduce fat intake and symptomatic treatment with analgesics as needed. Patient education regarding the benign nature of adenomyomatosis and the potential for symptom recurrence was provided. Follow-up ultrasound is scheduled in six months to monitor for any changes. Medical coding will utilize ICD-10 code K82.2 for adenomyomatosis of gallbladder. This documentation supports medical necessity for the diagnostic testing and ongoing management of this condition.
Common questions and answers
How can I differentiate gallbladder adenomyomatosis from gallbladder carcinoma on imaging, particularly ultrasound and MRI?+
Differentiating gallbladder adenomyomatosis from gallbladder carcinoma can be challenging, especially on imaging. While both conditions can present with thickened gallbladder walls and intramural cystic spaces (Rokitansky-Aschoff sinuses) on ultrasound, certain features can help distinguish them. In adenomyomatosis, the cystic spaces are typically small and comet-tail artifacts are common. Carcinoma, on the other hand, may demonstrate irregular wall thickening, an intraluminal mass, or vascular invasion. MRI can provide further clarity with its ability to visualize the Rokitansky-Aschoff sinuses and assess for enhancing mural nodules suggestive of malignancy. T2-weighted images are particularly useful for identifying the high signal intensity characteristic of the RAS. Dynamic contrast-enhanced MRI can also highlight differences in enhancement patterns, with carcinoma showing more rapid and irregular enhancement. Explore how advanced imaging techniques like diffusion-weighted imaging and MRCP can further aid in the differential diagnosis. Consider implementing a multiparametric imaging approach for complex cases to improve diagnostic accuracy. If imaging is inconclusive, biopsy may be necessary for definitive diagnosis.
What are the best management strategies for asymptomatic gallbladder adenomyomatosis incidentally discovered during abdominal imaging?+
Asymptomatic gallbladder adenomyomatosis discovered incidentally usually does not require surgical intervention. Current guidelines recommend a conservative approach with watchful waiting, especially when the diagnosis is confidently made based on imaging features. This involves patient education about the benign nature of the condition and regular follow-up if needed. Consider implementing a periodic ultrasound surveillance strategy in select patients with indeterminate findings to monitor for any concerning changes over time. It is important to discuss the potential risks and benefits of surgery versus continued surveillance with the patient. Learn more about the role of patient-reported outcomes in guiding management decisions for asymptomatic gallbladder adenomyomatosis.
When is cholecystectomy indicated for patients with symptomatic gallbladder adenomyomatosis, and what surgical approach is recommended?+
Cholecystectomy is indicated for patients with symptomatic gallbladder adenomyomatosis experiencing biliary colic, chronic right upper quadrant pain, or other symptoms attributable to the condition despite conservative management. The surgical approach can be laparoscopic, open, or robotic, with laparoscopic cholecystectomy being the preferred method for most patients due to its minimally invasive nature and faster recovery time. Open cholecystectomy might be considered in cases of severe inflammation, extensive adhesions, or suspected malignancy. Explore how factors such as patient comorbidities, surgeon experience, and local resources influence the choice of surgical approach. Consider implementing standardized surgical protocols and postoperative care pathways to optimize patient outcomes after cholecystectomy for gallbladder adenomyomatosis.
