We propose to revise the criteria in the Listing of Impairments (the listings) that we use to evaluate claims involving impairments that affect multiple body systems. We apply these criteria when you claim benefits based on disability under title II and title XVI of the Social Security Act (the Act). The proposed revisions reflect current medical knowledge, treatment, and methods of evaluating impairments that affect multiple body systems.

Under both the title II and title XVI programs, disability must be the result of any medically determinable physical or mental impairment or combination of impairments that meets the statutory duration requirement; that is, it must be expected to result in death or must have lasted or be expected to last for a continuous period of at least 12 months. Our definitions of disability are shown in the following table:
We use the listings only to decide that people are disabled or that they are still disabled. We will never deny your claim or decide that you no longer qualify for benefits because your impairment(s) does not meet or medically equal a listing. If you have a severe impairment(s) that does not meet or medically equal any listing, we may still find you disabled based on other rules in the “sequential evaluation process” that we use to evaluate all disability claims. (See §§ 404.1520, 416.920, and 416.924.)
Also, when we conduct reviews to determine whether your disability continues, we will not find that your disability has ended based only on any changes in the listings. Our regulations explain that, when we change our listings, we continue to use our prior listings when we review your case, if you qualified for disability benefits or SSI payments based on our determination or decision that your impairment(s) met or medically equaled the listings. In these cases, we determine whether you have experienced medical improvement, and if so, whether the medical improvement is related to the ability to work. If your condition(s) has medically improved so that you no longer meet or medically equal the prior listing, we evaluate your case further to determine whether you are currently disabled. We may find that you are currently disabled, depending on the full circumstances of your case. See §§ 404.1594(c)(3)(i) and 416.994(b)(2)(iv)(A). If you are a child who is eligible for SSI payments, we follow a similar rule after we decide that you have experienced medical improvement in your condition(s). See § 416.994a(b)(2).
We last published final rules revising the adult listings for impairments that affect multiple body systems in the Federal Register on May 19, 2000 (65 FR 31800); the rules were effective on June 19, 2000. In that document, we said that those rules would be effective for 8 years unless we extended them, or revised and issued them again. The current adult (Part A) listings for impairments that affect multiple body systems will no longer be effective on June 19, 2008 unless we extend them, or revise and issue them again.
We last published final rules revising the childhood listings for impairments that affect multiple body systems in the Federal Register on December 12, 1990 (55 FR 51204). The current childhood (Part B) listings for impairments that affect multiple body systems will no longer be effective on July 2, 2003 (66 FR 34361).
We are proposing these revisions because we decided to update the medical criteria in the listings and to provide more information about how we evaluate impairments that affect multiple body systems.
Change the name of this body system listing from “Multiple Body Systems” to “Impairments That Affect Multiple Body Systems,”
Expand, update, and reorganize the introductory text,
Remove current listing 110.07,
Make conforming changes, when applicable, in related regulations, and
We are proposing to change the name of this body system listing from “Multiple Body Systems” to “Impairments That Affect Multiple Body Systems” to more accurately Start Printed Page 78198reflect that we use this listing to evaluate single impairments that affect two or more body systems.
To provide additional guidance, we propose to expand, update, and reorganize the introductory text to the listing of impairments that affect multiple body systems. A detailed description of the proposed introductory text follows.
This section expands and clarifies current 10.00A, “Down syndrome (except for mosaic Down syndrome)” and provides a description of Down syndrome:
Proposed 10.00A1 explains that we evaluate non-mosaic Down syndrome under this body system listing.
Proposed 10.00A2 is a new paragraph that describes Down syndrome and explains that it exists in “non-mosaic” and “mosaic” forms.
Proposed 10.00A3a describes non-mosaic Down syndrome. Proposed 10.00A3b explains that we evaluate non-mosaic Down syndrome under proposed listing 10.06. It also explains that, if you have confirmed non-mosaic Down syndrome, we consider you disabled from birth. This provision is currently part of listing 10.06, but we propose to move it here, because it is a criterion for establishing when the person is first disabled under our rules, which belongs in the introductory text.
Proposed 10.00A4a describes mosaic Down syndrome. Proposed 10.00A4b explains that we evaluate adults with confirmed mosaic Down syndrome under the listing criteria for the affected body system(s) on an individual case basis and refers to 10.00C for an explanation of how we adjudicate claims involving mosaic Down syndrome.
This section, which expands and modifies current 10.00B, explains the documentation we need to establish that you have an impairment(s) that affects multiple body systems. There are two subsections:
Proposed 10.00B1 explains that the documentation we need to establish the existence of a medically determinable impairment must come from an acceptable medical source. We require such documentation for any impairment. The documentation must include a clinical description of the abnormal physical findings and definitive laboratory tests, including chromosomal analysis, where appropriate.
Proposed 10.00B2 explains that, in lieu of a copy of the actual laboratory report, we will accept medical evidence that is persuasive that a positive diagnosis has been confirmed by appropriate laboratory testing at some time prior to our evaluation. This section includes the guidance in current 10.00B on what we mean by medical evidence that is “persuasive.”
Proposed 10.00C1 explains that if your severe impairment(s) that affects multiple body systems does not meet the listing in this body system, we must consider whether you have another impairment(s) that meets the criteria of a listing in another body system.
Proposed 10.00C2 gives some examples of the many other impairments that can affect multiple body systems, such as trisomy X syndrome, fragile X syndrome, phenylketonuria (PKU), caudal regression syndrome, and fetal alcohol syndrome. We also explain that, because the body systems that these impairments can affect vary, and the effects on each body system can differ in severity and progression, we would evaluate these impairments under the listing criteria of the affected body system on an individual case basis. Proposed 10.00C2 generally corresponds to current 10.00C.
Proposed 10.00C3 explains that, if you have a severe medically determinable impairment(s) that does not meet a listing, we will consider whether your impairment(s) medically equals a listing. If not, we will proceed to the fourth and, if necessary, fifth steps of the sequential evaluation process in §§ 404.1520 and 416.920. We explain that we follow the rules in §§ 404.1594 and 416.994, as appropriate, when we decide whether you continue to be disabled.
The following is an explanation of the proposed changes to the listing.
We propose to simplify the heading to make it clear that we evaluate only non-mosaic Down syndrome under this listing. We also propose to move the last sentence of current 10.06 to proposed 10.00A3b because it is a criterion for establishing when the person is first disabled under our rules, which belongs in the introductory text.
If the same criteria exist in both the adult and childhood rules, we propose to make the same changes in the childhood rules that we propose for the adult rules for the same reasons we made the changes in the adult rules.
To provide additional guidance, we propose to expand, update, and reorganize the introductory text to the listing of impairments that affect multiple body systems. A description of the proposed introductory text follows.
This section describes the kinds of impairments that we evaluate under these listings.
Proposed 110.00A1 explains that we use these listings when a single impairment affects two or more body systems, and describes what kinds of impairments we evaluate under these listings. We also provide a brief description of the effects that these impairments generally have on a child's ability to perform age-appropriate activities and explain how we use the term “very seriously.”
Proposed 110.00A2 describes Down syndrome.
Proposed 110.00A3a describes non-mosaic Down syndrome. Proposed 110.00A3b explains that we evaluate children with confirmed non-mosaic Down syndrome under proposed listing 110.06.
Proposed 110.00A4a describes mosaic Down syndrome. Proposed 110.00A4b explains that we evaluate children with confirmed mosaic Down syndrome under the listing criteria for the affected body system(s) on an individual case basis.
Proposed 110.00A5a describes what we mean by “catastrophic congenital abnormalities or diseases.” We explain that it is reasonably certain that these abnormalities and diseases result in early death or interfere very seriously with development. “Very seriously” is consistent with our definition of “extreme” limitation in § 416.926a(e)(3). Start Printed Page 78199Proposed 110.00A5b explains that we evaluate catastrophic congenital abnormalities or diseases under proposed listing 110.08.
This section, which expands and modifies current 110.00B, explains the documentation we need to establish that you have an impairment(s) that affects multiple body systems. There are two subsections:
Proposed 110.00B1 explains the documentation we need to establish that you have a medically determinable impairment. This section is substantively the same as proposed section 10.00B1 of the part A listings for adults.
Proposed 110.00B2 explains what medical evidence we will accept in lieu of a copy of the actual laboratory report. The medical evidence must be persuasive that a positive diagnosis has been confirmed by appropriate laboratory testing at some time prior to our evaluation. This section is substantively the same as proposed section 10.00B2 of the part A listings for adults.
Proposed 110.00C is substantively similar to proposed section 10.00C of the part A listings for adults.
Proposed 110.00C1 explains that if your severe impairment(s) that affects multiple body systems does not meet the criteria for a listing in this body system, we must also consider whether you have an impairment(s) that meets the criteria of a listing in another body system.
Proposed 110.00C2 gives some examples of the many other impairments that can affect multiple body systems, such as trisomy X syndrome, fragile X syndrome, phenylketonuria (PKU), caudal regression syndrome, and fetal alcohol syndrome. We also explain that, because the body systems that these impairments can affect vary, and the effects on each body system can differ in severity and progression, we would evaluate these impairments under the listing criteria of any affected body system on an individual case basis.
Proposed 110.00C3 explains that, if your severe medically determinable impairment(s) does not meet a listing, we will consider whether your impairment(s) medically equals a listing or, in the case of a claim for SSI payments, functionally equals the listings. Proposed 110.00C3 also explains that if you are a child receiving SSI payments, we use the rules in § 416.994a to decide whether you continue to be disabled.
The following is an explanation of the proposed changes to the listings.
We propose to simplify the heading to make it clear that we evaluate only non-mosaic Down syndrome under this listing. We also propose to move the last sentence of current 110.06 to proposed 110.00A3b because it is a criterion for establishing when the child is first disabled under our rules, which belongs in the introductory text.
We propose to remove current listing 110.07 for two reasons.
First, the A criterion in this listing, published December 12, 1990, was created to evaluate physical impairments in infants or young children. We wrote this listing before we had the policy of functional equivalence (§ 416.926a) to help adjudicators evaluate physical impairments in very young children. Current listing 110.07A is now outdated and unnecessary because we have made a number of changes in our other listings and regulations, including the implementation of the functional equivalence policy more than 10 years ago, that provide better rules for evaluating infants and toddlers.
Second, the remaining criteria, 110.07B through F, are solely reference listings that refer adjudicators to another listing for the affected body system. As we update the listings in each of the body systems, we are removing reference listings because they are redundant.
In proposed 110.08, we explain that such abnormalities and diseases are generally regarded as being incompatible with prolonged life outside the uterus (110.08A) or interfere very seriously with development (110.08B). In proposed 110.08A, we are changing the phrase “incompatible with extrauterine life” in current listing 110.08A to “incompatible with prolonged life outside the uterus” to recognize that children with some catastrophic congenital abnormalities or diseases may live for many months or even a few years. In proposed 110.08B, we are changing the phrase “attainment of the growth and development of 2 years is not expected to occur” in the current listing to “interfere very seriously with development.” The new language takes into consideration advances in evaluation and management of these abnormalities and diseases, and is consistent with our definition of “extreme” limitation in § 416.926a(e)(3). We also propose to make listing 110.08 clearer and easier to understand by:
Changing the word “abnormalities” in current listing 110.08 to “abnormality” to emphasize that there need be only a single abnormality or disease involved; and
Moving the requirement for “a positive diagnosis” from current listings 110.08A and B to the opening statement in proposed listing 110.08.
We propose to remove the last sentence of 101.00B2c(2), “How we assess inability to perform fine and gross movements in very young children,” in the introductory text of the childhood musculoskeletal listings, because it refers adjudicators to current 110.07A, which we propose to remove from the multiple body listings. We propose to replace the reference to 110.07A with the following statement: “For such children, an extreme level of limitation means skills or performance at no greater than one-half of age-appropriate expectations based on an overall developmental assessment rather than on one or two isolated skills.” This statement provides clearer guidance for assessing extreme limitation of fine and gross movements in very young children, and is the same guidance we provide in 101.00B2b(2).
We propose to change the presumptive disability citation for Down syndrome in § 416.934, “Impairments which may warrant a finding of presumptive disability or presumptive blindness” (§ 416.934(g)) from “Allegation of Down's syndrome (Mongolism)” to “Allegation of Down Syndrome.” This will update the language of our rules to reflect current terminology.
Executive Order (E.O.) 12866, as amended by E.O. 13258, requires each agency to write all rules in plain language. In addition to your Start Printed Page 78200substantive comments on these proposed rules, we invite your comments on how to make these proposed rules easier to understand.
We have consulted with the Office of Management and Budget (OMB) and determined that these proposed rules meet the criteria for a significant regulatory action under E.O. 12866, as amended by E.O. 13258. Thus, they were subject to OMB review.
These proposed rules contain reporting requirements at 10.00B, 10.00C, 110.00B, and 110.00C. The public reporting burden is accounted for in the Information Collection Requests for the various forms that the public uses to submit the information to SSA. Consequently, a 1-hour placeholder burden is being assigned to the specific reporting requirement(s) contained in these rules. We are seeking clearance of the burdens referenced in these rules because they were not considered during the clearance of the forms. An Information Collection request has been submitted to OMB. We are soliciting comments on the burden estimate; the need for the information; its practical utility; ways to enhance its quality, utility and clarity; and on ways to minimize the burden on respondents, including the use of automated collection techniques or other forms of information technology. Comments should be submitted to the Social Security Administration at the following address: Social Security Administration, Attn: SSA Reports Clearance Officer, Rm. 1338 Annex Building, 6401 Security Boulevard, Baltimore, MD 21235-6401.

2. Item 11 in the introductory text before part A of appendix 1 to subpart P of part 404 is revised to read as follows:
11. Impairments That Affect Multiple Body Systems (10.00 and 110.00): [Date 8 years after effective date of final regulations.]
3. The list of sections for part A is amended by revising the heading for section 10.00 to read as follows:
4. Listing 10.00, Multiple Body Systems, of part A of appendix 1 of subpart P of part 404 is revised to read as follows:
1. General. We evaluate non-mosaic Down syndrome under this body system listing.
2. What is Down syndrome? Down syndrome is a chromosomal condition, present before birth, in which there are three chromosomes 21 instead of two. The three chromosomes may be separate (trisomy) or one chromosome may be attached to another (translocation). The extra chromosomal material changes the orderly development of the body and brain. Down syndrome is characterized by a complex of physical characteristics, delayed physical development, and mental retardation. It is often accompanied by heart disease, vision defects, chronic respiratory infections, and other conditions. It exists in non-mosaic and mosaic forms.
a. Non-mosaic Down syndrome occurs when the extra chromosome is replicated in every cell of the body. This form of Down syndrome is responsible for 95 percent of all cases. Virtually all cases of non-mosaic Down syndrome affect the mental, neurological, and skeletal systems, and often other body systems such as cardiac, endocrine, and gastrointestinal.
4. What is mosaic Down syndrome? Start Printed Page 78201
a. Mosaic Down syndrome occurs when you have some cells with normal chromosomes and some cells with extra chromosomal material. When this occurs, there is a mixture of two types of cells. Some of the cells contain 46 chromosomes and some of the cells contain 47 chromosomes. Mosaic Down syndrome occurs far less frequently than non-mosaic Down syndrome and can have features that manifest in a wide range of severity. Mosaic Down syndrome can be profound and disabling, but it also can be so slight as to be undetected clinically.
b. We evaluate adults with confirmed mosaic Down syndrome under the listing criteria for the affected body system(s) on an individual case basis, as described in 10.00C.
1. General. We need documentation from an acceptable medical source as defined in §§ 404.1513(a) and 416.913(a) to establish that you have a medically determinable impairment. The documentation must include a clinical description of the abnormal physical findings and definitive laboratory tests, including chromosomal analysis, where appropriate.
2. What will we accept as medical evidence in lieu of the actual laboratory report? When the actual laboratory report is unavailable, we will accept medical evidence that is persuasive that a positive diagnosis has been confirmed by appropriate laboratory testing at some time prior to our evaluation. To be persuasive, a report from an acceptable medical source must state that appropriate testing was conducted and the results confirmed the diagnosis. The report must be consistent with other evidence in your case record, for example, the description of abnormal physical findings, your educational history, or, if available, the results of psychological testing.
1. Non-mosaic Down syndrome (10.06) is an example of a common impairment that affects multiple body systems that we consider severe enough to prevent you from doing any gainful activity. If your severe impairment(s) does not meet the criteria of this listing, we must also consider whether you have an impairment(s) that meets the criteria of a listing in another body system.
2. There are many other impairments that cause deviation from, or interruption of, the normal function of the body, but the degree of deviation may vary widely from person to person. Therefore, the resulting functional limitations and the progression of those limitations also vary widely. For these reasons, we will evaluate these impairments on an individual case basis under the listing criteria in any affected body system. Examples of such impairments include trisomy X syndrome, fragile X syndrome, phenylketonuria (PKU), caudal regression syndrome, and fetal alcohol syndrome.
3. If you have a severe medically determinable impairment(s) that does not meet a listing, we will consider whether your impairment(s) medically equals a listing. (See §§ 404.1526 and 416.926.) If your impairment(s) does not meet or medically equal a listing, you may or may not have the residual functional capacity to engage in substantial gainful activity. In that situation, we proceed to the fourth and, if necessary, the fifth steps of the sequential evaluation process in §§ 404.1520 and 416.920. If you are an adult, we use the rules in §§ 404.1594 and 416.994, as appropriate, when we decide whether you continue to be disabled.
10.06 Non-mosaic Down syndrome, established by clinical and laboratory findings, as described in 10.00B.
5. The list of sections for part B is amended by revising the heading title for section 110.00 to read as follows:
110.00 Impairments That Affect Multiple Body Systems.
6. Section B.2.c.(2) of the introductory text of 101.00, Musculoskeletal System, of Part B of appendix 1 of Subpart P of part 404 is revised to read as follows:
(2) How we assess inability to perform fine and gross movements in very young children. For very young children, the consideration is limitations in the ability to perform comparable age-appropriate activities involving the upper extremities given normal developmental expectations. For such children, an extreme level of limitation means skills or performance at no greater than one-half of age-appropriate expectations based on an overall developmental assessment rather than on one or two isolated skills.
7. Listing 110.00, Multiple Body Systems, of part B of appendix 1 of subpart P of part 404 is revised to read as follows:
1. General. We use these listings when a single impairment affects two or more body systems. Under these listings, we evaluate impairments that affect multiple body systems due to non-mosaic and mosaic Down syndrome or a catastrophic congenital abnormality or disease. These kinds of impairments generally produce long-term, if not lifelong, interference with age-appropriate activities. Some of them result in early death or interfere very seriously with development. We use the term “very seriously” in these listings to describe an “extreme” limitation of functioning as defined in § 416.926a(e)(3).
2. What is Down syndrome? Down syndrome is a chromosomal condition, present before birth, in which there are three chromosomes 21 instead of two. The three chromosomes may be separate (trisomy) or one chromosome may be attached to another (translocation). This extra chromosomal material changes the orderly development of the body and brain. Down syndrome is characterized by a complex of physical characteristics, delayed physical development, and mental retardation. It is often accompanied by heart disease, vision defects, chronic respiratory infections, and other conditions. It exists in non-mosaic and mosaic forms.
b. We evaluate children with confirmed non-mosaic Down syndrome under listing 110.06. If you have confirmed non-mosaic Down syndrome, we consider you disabled from birth.
b. We evaluate children with confirmed mosaic Down syndrome under the listing criteria for the affected body system(s) on an individual case basis.
a. Catastrophic congenital abnormalities or diseases are present at birth although they may not be apparent immediately. They cause deviation from, or interruption of, the normal function of the body and are reasonably certain to result in early death or interfere very seriously with development.
b. We evaluate catastrophic congenital abnormalities or diseases under listing 110.08.
1. General. We need documentation from an acceptable medical source as defined in §§ 404.1513(a) and 416.913(a) to establish Start Printed Page 78202that you have a medically determinable impairment. The documentation must include a clinical description of the abnormal physical findings and definitive laboratory tests, including chromosomal analysis, where appropriate.
2. What will we accept as medical evidence in lieu of the actual laboratory report? When the actual laboratory report is unavailable, we will accept medical evidence that is persuasive that a positive diagnosis has been confirmed by appropriate laboratory testing at some time prior to our evaluation. To be persuasive, a report from an acceptable medical source must state that appropriate testing was conducted and that the results confirmed the diagnosis. The report must be consistent with other evidence in your case record, for example, the description of abnormal physical findings, your educational history, or, if available, the results of psychological testing.
1. These listings are examples of common impairments that affect multiple body systems that we consider severe enough to result in marked and severe functional limitations. If your severe impairment(s) does not meet the criteria of any of these listings, we must also consider whether you have an impairment(s) that meets the criteria of a listing in another body system.
2. There are many other impairments that cause deviation from, or interruption of, the normal function of the body, but the degree of deviation may vary widely from child to child. Therefore, the resulting functional limitations and the progression of those limitations are more variable than with catastrophic congenital abnormalities or diseases described in 110.00A5. For these reasons, we evaluate these impairments on an individual case basis under the listing criteria in any affected body system. Examples of such impairments include trisomy X syndrome, fragile X syndrome, phenylketonuria (PKU), caudal regression syndrome, and fetal alcohol syndrome.
3. If you have a severe medically determinable impairment(s) that does not meet a listing, we will consider whether your impairment(s) medically equals a listing, and, in the case of a claim for SSI payments, functionally equals the listings. (See §§ 404.1526, 416.926, and 416.926a.) If you are receiving SSI payments, when we decide whether you continue to be disabled, we use the rules in § 416.994a.
110.06 Non-mosaic Down syndrome, established by clinical and laboratory findings, as described in 110.00B.
110.08 A catastrophic congenital abnormality or disease. With a positive diagnosis as described in 110.00B, AND THAT:
A. Is generally regarded as being incompatible with prolonged life outside the uterus (for example, anencephaly, trisomy D or E, cyclopia);
B. Interferes very seriously with development; for example, 5p-syndrome (cri du chat) or Tay-Sachs disease.
