Body system 5.00 in the SSA Blue Book covers digestive disorders for adult (Part A). SSA uses these listings at step 3 of its five-step disability evaluation. If your medical evidence meets one of the listings on this page, your claim is approved without the disability examiner moving on to past-work and labor-market analysis at steps 4 and 5.
Most claimants who do not meet a listing in this body system can still be approved at later steps based on their residual functional capacity, age, education, and past work. The medical evidence you build for a listing-match argument is the same evidence those later steps rely on, so the listing criteria are useful to read even when a claim looks like a step-5 approval candidate.

How SSA describes this body system
Excerpted from SSA's regulatory introduction at the top of the body-system page. Full text and all subsection cross-references live on ssa.gov.
Digestive Disorders A. Which digestive disorders do we evaluate in this body system? We evaluate digestive disorders that result in severe dysfunction of the liver, pancreas, and gastrointestinal tract (the large, muscular tube that extends from the mouth to the anus, where the movement of muscles, along with the release of hormones and enzymes, allows for the digestion of food) in this body system. Examples of these disorders and the listings we use to evaluate them include chronic liver disease ( 5.05 ), inflammatory bowel disease ( 5.06 ), and intestinal failure ( 5.07 ). We also use this body system to evaluate gastrointestinal hemorrhaging from any cause ( 5.02 ), weight loss due to any digestive disorder ( 5.08 ), liver transplantation ( 5.09 ), small intestine transplantation ( 5.11 ), and pancreas transplantation ( 5.12 ). We evaluate cancers affecting the digestive system under the listings in 13.00 . B. What evidence do we need to evaluate your digestive disorder? 1. General. To establish that you have a digestive disorder, we need medical evidence about the existence of your digestive disorder and its severity. Medical evidence should include your medical history, physical examination findings, operative reports, and relevant laboratory findings. 2. Laboratory findings. We need laboratory reports such as results of imaging (see 5.00B3 ), endoscopy, and other diagnost...

What happens during a claim under 5.00
The disability examiner assigned to your claim looks for medical records that match the lettered criteria of one of the listings above. The examiner does not diagnose you and does not weigh symptoms in isolation. They line up the listing's required findings against your records and decide whether the records contain enough to satisfy the listing as written.
If your records meet a listing, the claim is approved at step 3. If not, the examiner moves on to evaluating your residual functional capacity (RFC) at steps 4 and 5. RFC is a description of what work activity you can still do despite your impairments. The listings inform the RFC because the same medical evidence the listings ask for is the evidence the examiner uses to write the RFC. The disability overview walks through the full five-step evaluation in plain English.
Work activity, SGA, and the SSDI gate
A claim under any Blue Book listing is denied at step 1 if you are working at or above the substantial gainful activity threshold. SGA is the monthly earnings test SSA applies before any medical evaluation. Earning above SGA in countable work activity means SSA never reaches the listings on this page. Earning below SGA, or being out of work entirely, lets the medical evaluation proceed.
Once you are approved and receiving SSDI, the trial work period and extended period of eligibility apply differently than at the initial-application stage. Both are explained on the SGA amount page with year-by-year thresholds since 1975.
Children's listings for the same body system
SSA publishes a parallel body system at 105.00 for the children's (under 18) side of the same conditions. Many listings cross over with tighter functional thresholds for the children's version. The Digestive system (children) page covers the 9 active listings on that side.
