To meet Listing 13.18 for large intestine cancer, you must provide medical evidence of adenocarcinoma that is inoperable, unresectable, or recurrent, or evidence of squamous cell carcinoma of the anus that has recurred. The SSA also considers cases with distant metastases or small-cell carcinoma. You should provide pathology reports and imaging that document your cancer's stage and current status, alongside physician notes on your functional limitations. An attorney can help you organize this evidence to support your claim.
What this listing covers
Large intestine cancer involves the growth of malignant cells in the colon or the anal canal. This condition begins when healthy cells in the lining of the bowel develop mutations that cause them to grow uncontrollably, forming tumors that can spread to other parts of your body.
The physical impact of this cancer and its treatment is often severe. You may experience chronic fatigue, persistent bowel dysfunction, and significant pain that interferes with your ability to sit, stand, or maintain the concentration required for a full-time job. These symptoms often persist even after surgical intervention or during ongoing chemotherapy.
How SSA evaluates a claim under this listing
Under Listing 13.18, the SSA evaluates the severity of your large intestine cancer based on the type of tumor and its spread. They look for evidence of adenocarcinoma that is inoperable, unresectable, or recurrent. For squamous cell carcinoma of the anus, they specifically look for cases that have recurred after your initial surgical treatment.
The SSA also considers the extent of your disease, specifically if the cancer has metastasized beyond your regional lymph nodes or if it is identified as small-cell carcinoma. The listing requires medical documentation that confirms your diagnosis and the current status of your disease, as these factors determine whether your impairment meets the threshold for disability.
Evidence that strengthens a claim
To strengthen your claim, you must provide comprehensive medical records, including pathology reports from your biopsies or surgical procedures. The SSA requires documentation that specifies the site of your primary lesion, the extent of your cancer, and any evidence of metastasis. Imaging studies, such as CT scans or MRIs, are essential to demonstrate the current progression of your disease.
Non-medical evidence is also vital, such as detailed treatment notes that describe your response to chemotherapy, radiation, or surgery. Statements from your treating physicians regarding your functional limitations, such as your inability to perform daily tasks or sustain work-related activities, help provide a complete picture of how the cancer affects your ability to function. An attorney can help you gather this evidence to ensure your claim is complete.
How an attorney helps
A disability attorney helps by ensuring your medical records are organized and clearly mapped to the specific criteria of Listing 13.18. They can work with your medical team to obtain functional capacity statements that document your limitations and help prepare your case for potential hearings. By managing the complexities of the application process, an attorney ensures that your evidence is presented in a way that aligns with what the SSA looks for when evaluating cancer claims.
Frequently asked questions
Not automatically. The SSA evaluates your claim based on whether your specific diagnosis meets the criteria in Listing 13.18, such as the cancer being inoperable, recurrent, or having spread beyond regional lymph nodes. An attorney can review your medical records to see if they align with these requirements.
The most critical evidence includes your pathology reports, operative notes, and imaging studies that confirm the stage and spread of your cancer. The SSA needs clear documentation of the primary site and any evidence of recurrence or metastasis. Having a consistent record of your treatment and its side effects is also essential.
The SSA considers the side effects of anticancer therapy, such as persistent fatigue, neurological complications, or gastrointestinal issues, when assessing your ability to work. They look at how these symptoms impact your daily functioning over time. An attorney can help you document these side effects to ensure they are properly considered in your claim.
If your claim is denied, you have the right to file an appeal, starting with a request for reconsideration. If that is also denied, you can request a hearing before an ALJ to present your case. There are strict deadlines for these appeals, so consulting with an attorney early can help you navigate the process.
