What this listing covers

Hematological disorders involve non-cancerous conditions that disrupt the production or function of blood cells and clotting factors. This includes hemolytic anemias like sickle cell disease, clotting disorders such as hemophilia, and bone marrow failure syndromes like aplastic anemia. These conditions prevent your body from maintaining healthy blood levels, leading to chronic health complications.

These disorders often cause severe fatigue, pain, and frequent infections that make maintaining a regular work schedule difficult. You may struggle with the physical demands of lifting or standing, or the mental focus required to complete tasks. When symptoms are persistent, they can interfere with your daily activities like household chores, commuting, or interacting with others in a professional setting.

How SSA evaluates a claim under this listing

Under Listing 7.18, the Social Security Administration evaluates the impact of repeated complications from your blood disorder on your ability to function. SSA looks for evidence of marked limitations in one of three areas: activities of daily living, social functioning, or your ability to complete tasks due to deficiencies in concentration, persistence, or pace.

To meet the criteria, you must document that your complications occur frequently, typically averaging three times a year or once every 4 months. These complications must last at least 2 weeks or occur with enough frequency to disrupt your life. An attorney can help you document these functional impacts to ensure your claim meets SSA standards.

Evidence that strengthens a claim

Your claim relies on laboratory reports that definitively establish your diagnosis, such as hemoglobin electrophoresis or bone marrow biopsy results. SSA also requires detailed medical records documenting your history of complications, including hospitalizations, emergency room visits, and the specific treatments you have received to manage your condition.

Beyond lab results, statements from your treating physician are vital. These reports should detail how your symptoms, such as severe fatigue or pain, limit your daily functioning. Third-party reports from family members or former coworkers describing your inability to sustain tasks or interact appropriately can also provide necessary context for your functional limitations. An attorney can help you gather this evidence to build a stronger case.

Why claims fail

Many claims are denied because your medical evidence fails to link your blood disorder directly to a marked functional limitation. SSA often finds that while a diagnosis is documented, the record lacks specific evidence showing how your condition prevents you from performing work-related tasks. Additionally, if the frequency or duration of your complications does not meet the specific thresholds outlined in the Blue Book, your claim may be rejected. An attorney can help you identify these gaps and strengthen your application.

How an attorney helps

A disability attorney helps by ensuring your medical records are organized to clearly demonstrate how your hematological disorder meets the specific requirements of Listing 7.18. They can work with your doctors to obtain detailed functional capacity statements that bridge the gap between your diagnosis and your inability to work. By preparing your case for potential hearings, an attorney helps you present the most persuasive evidence possible to the Social Security Administration.
