RAILROAD RETIREMENT BOARD

20 CFR Part 220

RIN 3220-AB18


Determining Disability

AGENCY: Railroad Retirement Board.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Railroad Retirement Board hereby amends its regulations 
with respect to determining when an employee is disabled for his or her 
regular railroad occupation. This final rule gives effect to an 
agreement between railroad labor and railroad management consistent 
with section 2(a)(2) of the Railroad Retirement Act which provides that 
labor and management shall cooperate with the Board in developing 
standards for determining when an employee's physical or mental 
condition disables him or her for work in his or her regular railroad 
occupation and thus there exists good cause not to delay its 
effectiveness beyond date of publication.

DATES: Effective date: This rule is effective February 13, 1998.
    Applicability date: This rule shall be applicable February 13, 
1998, but only with respect to applications for a disability annuity 
filed on or after January 1, 1998.

ADDRESSES: Secretary to the Board, Railroad Retirement Board, 844 North 
Rush Street, Chicago, Illinois 60611.

FOR FURTHER INFORMATION CONTACT: Thomas W. Sadler, Senior Attorney, 
Railroad Retirement Board, 844 North Rush Street, Chicago, Illinois 
60611, (312) 751-4513, TDD (312) 751-4701.

SUPPLEMENTARY INFORMATION: Section 2(a)(2) of the Railroad Retirement 
Act (45 U.S.C. 231a(a)(2)) provides that the Board, with the 
cooperation of employers and employees, shall secure the establishment 
of standards determining the physical and mental conditions which 
permanently disqualify employees from performing their regular 
occupation in the railroad industry. The Board has never formally 
adopted such standards. The agency, in the past, has used provisional 
standards which were adopted in 1946 but which are now outdated. In 
1991 the Board adopted Subpart C of Part 220 which provides for 
determining disability for work in an employee's regular railroad 
occupation. Under this regulation if an employee's physical or mental 
condition does not meet a listing found in Appendix 1 of Part 220 
(which determines if an individual is able to engage in any employment 
both within and outside the railroad industry), the Board determines 
the employee's residual functional capacity and compares that to the 
demands of his or her regular railroad occupation to determine if the 
employee can continue to perform that job. However, Subpart C contains 
no specific standards which relate to specific railroad occupations. 
The Board amends Subpart C to add such standards with respect to 
certain railroad occupations.
    Section 220.10 provides for the establishment of an Occupational 
Disability Advisory Committee made up of two physicians, one from 
recommendations from rail labor, one from recommendations of rail 
management. This committee shall review, from time to time, the 
disability standards developed by this regulation and the Occupational 
Disability Claims Manual (Manual) which supplements this regulation. 
The Board shall confer with this Committee before it amends this 
regulation or the Manual. It should be noted that the Board is not an 
agency subject to the Federal Advisory Committee Act. Accordingly, the 
Occupational Disability Advisory Committee will not be subject to that 
Act.
    Section 220.11 contains the definitions of ``regular railroad 
occupation'', ``permanent physical and mental impairment'', and 
``residual functional capacity'' as presently found in Part 220. In 
addition, it adds the definitions of ``independent case evaluation'' 
and ``functional capacity test''.
    The current Sec. 220.12 is removed, and the current Sec. 220.14 
``Evidence Considered'' is redesignated Sec. 220.12.
    The introductory language and paragraph (a) of section 220.13 
follow the present regulation and describe the sequential evaluation 
process for determining disability for an employee's regular railroad 
occupation. Initially, if an employee has been medically disqualified 
by his employer, the Board will presume that the employee is disabled 
for his regular railroad occupation if there is any objective medical 
evidence to support that determination. If the employee has not been so 
disqualified, the Board will determine if the employee's impairment(s) 
meet or equal a listing found in Appendix 1.
    Section 220.13(b)(1) provides that if an employee has not been 
found disabled in the first two steps described above, the Board will 
then determine the employee's regular railroad occupation, based upon 
the employee's description of his or her job.
    Section 220.13(b)(2)(i) provides that next the Board will determine 
if an employee's regular railroad occupation and impairment(s) are 
covered under the standards contained in a new Appendix 3 to Part 220. 
If both the occupation and impairment(s) are covered, the Board will 
confirm the existence of the impairment(s) by using the tests listed in 
Appendix 3 or by other valid diagnostic tests which could be used to 
establish an impairment as provided for in Sec. 220.27 of this part. 
(Section 220.13(b)(2)(ii) of the proposed rule has been revised to 
clarify how an impairment is confirmed and that if an employee's 
impairment(s) cannot be confirmed, as provided for in this section, the 
employee will be found not disabled.) Once the impairment(s) is 
confirmed, Appendix 3 is applied to determine if the employee is 
disabled. (Section 220.13(b)(2)(iii).)
    If the employee's regular railroad occupation and impairment(s) are 
not covered by Appendix 3, or if the medical evidence contains 
significant differences in interpretation of objective test findings 
which cannot be readily resolved, then the Board will not use Appendix 
3, but will determine if the employee is disabled using an independent 
case evaluation (ICE) as set forth in Sec. 220.13(b)(2)(iv). Likewise, 
if Appendix 3 does not yield a ``disabled'' finding, ICE will apply.
    Section 220.13(b)(2)(iv), which describes ICE, is essentially a 
more detailed description of the process, which is described in 
Sec. 220.13(b)(3) of the present regulation. Under this process the 
Board initially determines whether the evidence is complete (Step 1). 
The Board next confirms any impairment which has not been confirmed 
under Sec. 220.13(b)(2)(ii) (Step 2). Next, the Board will determine 
whether there is a concordance of medical findings among physicians. If 
there is not, the Board will request additional medical evidence from 
the employee's treating physician(s) or procure additional consulting 
exams (Step 3). Once the Board establishes a concordance of medical 
findings, to the extent that it is possible, it will then assess the 
quality of the medical evidence under the factors set forth in 
Sec. 220.14. This section sets forth factors which either support or 
call into question the validity of the medical findings. Thus, for 
example, the opinion of a treating physician, which is fully supported 
by medically acceptable clinical and diagnostic techniques, is given 
greater weight than one that is not so supported or is inconsistent 
with findings of other medical sources. Likewise, the claimant's 
description of

[[Page 7539]]

his or her own condition, if consistent with objective medical 
findings, is given more weight than one that is not consistent (Step 
4). If, after assessment, the Board determines that there is no 
substantial objective evidence of an impairment, the Board will 
determine that the employee is not disabled.
    If through the assessment in Step 4 it is determined that there is 
substantial objective evidence of an impairment, then in Step 5 the 
Board will determine the demands of the employee's regular railroad 
occupation. At this point, the Board will not only consider the 
employee's own description of his or her job, but also the employer's 
description as well as other sources such as the Dictionary of 
Occupational Titles and generic descriptions found in the Occupational 
Disability Claims Manual.
    Next, the Board will determine the employee's residual functional 
capacity based upon the assessment performed in Step 4 and compare it 
to the job demands determined in Step 5. If the demands of the 
employee's regular railroad occupation exceed the employee's residual 
functional capacity, then the Board will find the employee disabled. If 
the demands do not exceed the residual functional capacity, then the 
Board will find the employee not disabled (Step 6).
    The Board published this regulation as a proposed rule on September 
24, 1997 (62 FR 50056), and invited comments by October 24, 1997. Two 
comments were received. One commentator suggested that the Board adopt 
the vision and hearing acuity requirements found in 49 CFR 240.121, 
which have been adopted by the Federal Railroad Administration for 
certification of locomotive engineers. However, the Board does not feel 
such a change is needed since an engineer who is disqualified by his 
employer for failure to meet the requirements of 49 CFR 240.121 would 
ordinarily be presumed disabled under the first paragraph of 
Sec. 220.13. Another commentator expressed support for the regulation 
because it was in accord with an agreement reached in July 1997 between 
representatives of rail labor and rail management concerning 
occupational disability.
    The final rule contains an Introduction to Appendix 3 which 
explains how to use the Appendix. In addition, the Board has corrected 
typographical errors in Appendix 3, and made the following substantive 
changes in Appendix 3 based upon advice from physicians representing 
rail labor and rail management:

List of Subjects in 20 CFR Part 220

    Disability benefits, Railroad employees, Railroad retirement, 
Reporting and recordkeeping requirements.

    For the reasons set forth in the preamble, part 220 of title 20 of 
the Code of Federal Regulations is amended as follows:

PART 220--DETERMINING DISABILITY

    1. The authority citation for part 220 continues to read as 
follows:

    Authority: 45 U.S.C. 231a; 45 U.S.C. 231f.

    2. The heading of subpart C is revised to read as follows:

Subpart C--Disability Under the Railroad Retirement Act for Work in 
an Employee's Regular Railroad Occupation

    3. Section 220.10 is revised to read as follows:


Sec. 220.10  Disability for work in an employee's regular railroad 
occupation.

    (a) In order to receive an occupational disability annuity an 
eligible employee must be found by the Board to be disabled for work in 
his or her regular railroad occupation because of a permanent physical 
or mental impairment. In this subpart the Board describes in general 
terms how it evaluates a claim for an occupational disability annuity. 
In accordance with section 2(a)(2) of the Railroad Retirement Act this 
subpart was developed with the cooperation of employers and employees. 
This subpart is supplemented by an Occupational Disability Claims 
Manual (Manual) <SUP>1</SUP>  which was also developed with the 
cooperation of employers and employees.
---------------------------------------------------------------------------

    \1\ The Manual may be obtained from the Board's headquarters at 
844 North Rush Street, Chicago, IL 60611.
---------------------------------------------------------------------------

    (b) In accordance with section 2(a)(2) of the Railroad Retirement 
Act, the Board shall select two physicians, one from recommendations 
made by representatives of employers and one from recommendations made 
by representatives of employees. These individuals shall comprise the 
Occupational Disability Advisory Committee (Committee). This Committee 
shall periodically review, as necessary, this subpart and the Manual 
and make recommendations to the Board with respect to amendments to 
this subpart or to the Manual. The Board shall confer with the 
Committee before it amends either this subpart or the Manual.
    4. Section 220.11 is revised to read as follows:


Sec. 220.11  Definitions as used in this subpart.

    Functional capacity test means one of a number of tests which 
provide objective measures of a claimant's maximal work ability and 
includes functional capacity evaluations which provide a systematic 
comprehensive assessment of a claimant's overall strength, mobility, 
endurance and capacity to perform physically demanding tasks, such as 
standing, walking, lifting, crouching, stooping or bending, climbing or 
kneeling.
    Independent Case Evaluation (ICE) means the process for evaluating 
claims not covered by Appendix 3 of this part.
    Permanent physical or mental impairment means a physical or mental 
impairment or combination of impairments that can be expected to result 
in death or has lasted or can be expected to last for a continuous 
period of not less than 12 months.
    Regular railroad occupation means an employee's railroad occupation 
in which he or she has engaged in service for hire in more calendar 
months than the calendar months in which he or she has been engaged in 
service for hire in any other occupation during the last preceding five 
calendar years, whether or not consecutive; or has engaged in service 
for hire in not less than one-half of all of the months in which he or 
she has been engaged in service for hire during the last preceding 15 
consecutive calendar years. If an employee last worked as an officer or 
employee of a railway labor organization and if continuance in such 
employment is no longer available to him or her, the ``regular 
occupation'' shall be the position to which the employee holds 
seniority rights or the position which he or she left to work for a

    Residual functional capacity has the same meaning as found in 
Sec. 220.120.


Sec. 220.12  [Removed]


Sec. 220.14  [Redesignated as Sec. 220.12]

    5. The current Sec. 220.12 ``Permanent physical or mental 
impairment, defined.'' is removed, and Sec. 220.14 ``Evidence 
considered.'' is redesignated as Sec. 220.12.
    6. Section 220.13 is amended by revising the section heading, the 
introductory text, and paragraph (b) to read as follows:

[[Page 7542]]

Sec. 220.13  Establishment of permanent disability for work in regular 
railroad occupation.

    The Board will presume that a claimant who is not allowed to 
continue working for medical reasons by his employer has been found, 
under standards contained in this subpart, disabled unless the Board 
finds that no person could reasonably conclude on the basis of evidence 
presented that the claimant can no longer perform his or her regular 
railroad occupation for medical reasons. (See Sec. 220.21 if the 
claimant is not currently disabled, but was previously occupationally 
disabled for a specified period of time in the past). The Board uses 
the following evaluation process in determining disability for work in 
the regular occupation:
* * * * *
    (b) If the Board finds that the claimant does not have an 
impairment described in paragraph (a) of this section, it will--
    (1) Determine the employee's regular railroad occupation, as 
defined in Sec. 220.11, based upon the employee's own description of 
his or her job;
    (2) Evaluate whether the claimant is disabled as follows:
    (i) The Board first determines whether the employee's regular 
railroad occupation is an occupation covered under Appendix 3 of this 
part. Second, the Board will determine whether the employee's claimed 
impairment(s) is covered under Appendix 3 of this part. If claimant's 
regular railroad occupation or impairment(s) is not covered under 
Appendix 3 of this part, then the Board will determine if the employee 
is disabled under ICE as set forth in paragraph (b)(2)(iv) of this 
section.
    (ii)(A) If the Board determines that, in accordance with paragraph 
(b)(2)(i) of this section, Appendix 3 of this part applies, then the 
Board will confirm the existence of the employee's impairment(s) 
using--
    (1) The ``highly recommended'' and ``recommended'' tests set forth 
in Appendix 3 of this part that relate to the body part affected by the 
claimant's impairment(s); or
    (2) By using valid diagnostic tests accepted by the medical 
community as described in Sec. 220.27.
    (B) If the employee's impairment(s) cannot be confirmed because 
there are significant differences in objective tests such as imaging 
study, electrocardiograms or other test results, and these differences 
cannot be readily resolved, the Board will determine if the employee is 
disabled under ICE as set forth in paragraph (b)(2)(iv) of this 
section. However, if the employee's impairment(s) cannot be confirmed, 
and there are no significant differences in objective medical tests 
which cannot be readily resolved, then the employee will be found not 
disabled.
    (iii) Once the impairment(s) is confirmed, as provided for in 
paragraph (b)(2)(ii) of this section, the Board will apply Appendix 3 
of this part. If Appendix 3 of this part dictates a ``D'' (disabled) 
finding, the Board will find the claimant disabled.
    (iv) If the Board does not find the employee disabled using the 
standards in Appendix 3 of this part, then the Board will determine if 
the employee is disabled using ICE. To evaluate a claim under ICE the 
Board will use the following steps:
    (A) Step 1. The Board will determine if the medical evidence is 
complete. Under this step the Board may request the claimant to take 
additional medical tests such as a functional capacity test or other 
consultative examinations;
    (B) Step 2. If the employee's impairment(s) has not been confirmed, 
as provided for in paragraph (b)(2)(ii)(A)(2) of this section, the 
Board will next confirm the employee's impairment(s), as described in 
paragraph (b)(2)(ii)(A)(2) of this section;
    (C) Step 3. The Board will determine whether the opinions among the 
physicians regarding medical findings are consistent, by reviewing the 
employee's medical history, physical and mental examination findings, 
laboratory or other test results, and other information provided by the 
employee or obtained by the Board. If such records reveal that there 
are significant differences in the medical findings, significant 
differences in opinions concerning the residual functional capacity 
evaluations among treating physicians, or significant differences 
between the results of functional capacity evaluations and residual 
functional capacity examinations, then the Board may request additional 
evidence from treating physicians, additional consultative examinations 
and/or residual functional capacity tests to resolve the 
inconsistencies;
    (D) Step 4. When the Board determines that there is concordance of 
medical findings, then the Board will assess the quality of the 
evidence in accordance with Sec. 220.112, which describes the weight to 
be given to the opinions of various physicians, and Sec. 220.114, which 
describes how the Board evaluates symptoms such as pain. The Board will 
also assess the weight of evidence by utilizing Sec. 220.14, which 
outlines factors to be used in determining the weight to be attributed 
to certain types of evidence. If, after assessment, the Board 
determines that there is no substantial objective evidence of an 
impairment, the Board will determine that the employee is not disabled;
    (E) Step 5. Next, the Board determines the physical and mental 
demands of the employee's regular railroad occupation. In determining 
the job demands of the employee's regular railroad occupation, the 
Board will not only consider the employee's own description of his or 
her regular railroad occupation, but shall also consider the employer's 
description of the physical requirements and environmental factors 
relating to the employee's regular railroad occupation, as provided by 
the employer on the appropriate form set forth in Appendix 3 of this 
part, and consult other sources such as the Dictionary of Occupational 
Titles and the job descriptions of occupations found in the 
Occupational Disability Claims Manual, as provided for in Sec. 220.10;
    (F) Step 6. Based upon the assessment of the evidence in paragraph 
(b)(2)(iv)(D) of this section, the Board shall determine the employee's 
residual functional capacity. The Board will then compare the job 
demands of the employee's regular railroad occupation, as determined in 
paragraph (b)(2)(iv)(E) of this section. If the demands of the 
employee's regular railroad occupation exceed the employee's residual 
functional capacity, then the Board will find the employee disabled. If 
the demands do not exceed the employee's residual functional capacity, 
then the Board will find the employee not disabled.
    7. A new section 220.14 is added to read as follows:


Sec. 220.14  Weighing of evidence.

    (a) Factors which support greater weight. Evidence will generally 
be given more weight if it meets one or more of the following criteria:
    (1) The residual functional capacity evaluation is based upon 
functional objective tests with high validity and reliability;
    (2) The medical evidence shows multiple impairments which have a 
cumulative effect on the employee's residual functional capacity;
    (3) Symptoms associated with limitations are consistent with 
objective findings;
    (4) There exists an adequate trial of therapies with good 
compliance, but poor outcome;
    (5) There exists consistent history of conditions between treating 
physicians and other health care providers.

[[Page 7543]]

    (b) Factors which support lesser weight. Evidence will generally be 
given lesser weight if it meets one or more of the following criteria:
    (1) There is an inconsistency between the diagnoses of the treating 
physicians;
    (2) There is inconsistency between reports of pain and functional 
impact;
    (3) There is inconsistency between subjective symptoms and physical 
examination findings;
    (4) There is evidence of poor compliance with treatment regimen, 
keeping appointments, or cooperating with treatment;
    (5) There is evidence of exam findings which is indicative of 
exaggerated or potential malingering response;
    (6) The evidence consists of objective findings of exams that have 
poor reliability or validity;
    (7) The evidence consists of imaging findings which are nonspecific 
and largely present in the general population;
    (8) The evidence consists of a residual functional capacity 
evaluation which is supported by limited objective data without 
consideration for functional capacity testing.
    8. Appendix 3--Railroad Retirement Board Occupational Disability 
Standards is added to part 220 to read as follows:

Appendix 3--Railroad Retirement Board Occupational Disability Standards

1. Introduction

    1.01  The Board uses this appendix to adjudicate the 
occupational disability claims of employees with medical conditions 
and job titles covered by the Tables in this appendix. The Tables 
are divided into ``Body Parts'', with each Body Part further divided 
by job title. Under each job title there is a list of impairments 
and tests with accompanying test results which establish a finding 
of ``D'' (disabled). The use of these Tables is a three-step 
process. In the first step we determine whether the employee's 
regular railroad occupation is covered by the Tables; next we 
establish the existence of an impairment covered by the Tables; 
finally, we reach a disability determination. If we do not find an 
employee disabled under these Tables, the employee may still be 
found disabled using Independent Case Evaluation (ICE), as explained 
in subpart C of this part.
    1.02  The Cancer Tables are treated in a different way than 
other body systems. Different types of cancer and their treatments 
have different functional impacts. In the Cancer Tables the impact 
of the impairment is seen as being significant or not significant. 
Therefore, these tables contain an ``S'' (significant) which is 
equivalent to a ``D'' rating. A detailed explanation of how to use 
those tables is in that section. The steps to use the remaining 
Tables are explained below:

2. Confirming the Impairment

    2.01  Once we determine that the employee's regular railroad 
occupation is covered by the Job Titles in the Tables, we must 
determine the existence of an impairment covered by the Tables. This 
is done through the use of Confirmatory Tests. These tests can 
include information from medical records, surgical or operative 
reports, or specific diagnostic test results. Confirmatory Tests are 
listed in the initial section regarding each Body Part covered in 
the Tables. If an impairment cannot be confirmed because of 
inconsistent medical information, ICE may be required.
    2.02  There are two types of Confirmatory Tests as follows.
    2.03  ``Highly Recommended'' Tests--The designation of a 
confirmatory test as being ``highly recommended'' means that the 
test is almost always performed to confirm the existence of the 
impairment. For many conditions, only one ``highly recommended'' 
test finding is suggested to confirm the impairment. However, there 
may be times when that test is not available or is negative, but 
other more detailed testing confirms the impairment.
    2.04  Example A: To confirm the condition of pulmonary 
hypertension, the Tables under Body Part C., Cardiac, designate as 
``highly recommended'': an electrocardiogram which indicates 
definite right ventricular hypertrophy. However, the impairment may 
also be confirmed by insertion of a Swan-Ganz catheter into the 
pulmonary artery and the pulmonary artery pressure measured 
directly.
    2.05  There may be some conditions for which several ``highly 
recommended'' tests are suggested to confirm an impairment. In these 
circumstances, we will use all ``highly recommended'' tests to 
establish the existence of the impairment.
    2.06  Example B: Under Body Part E., Lumbar Sacral Spine, three 
highly recommended medical findings are identified for the diagnosis 
of chronic back pain, not otherwise specified. These findings 
include:
    A. A history of back pain under medical treatment for at least 
one year, and
    B. A history of back pain unresponsive to therapy for at least 
one year, and
    C. A history of back pain with functional limitations for at 
least one year.
    2.07  All three of these criteria must be satisfied to confirm 
the existence of chronic back pain.
    2.08  Sometimes the employee may have undergone detailed testing 
which is as reliable as one of the ``highly recommended'' tests 
listed in the Tables. In cases where an impairment has not been 
confirmed by one of the designated ``highly recommended'' tests, the 
impairment may still be confirmed by ``recommended'' tests (see 
below) or by evidence acceptable under section 220.27 of this part.
    2.09  Recommended Tests--The designation of a confirmatory test 
as ``recommended'' means that the test need not be performed, or be 
positive, to confirm the impairment. However, a positive test 
provides significant support for confirming the impairment. If there 
are no ``highly recommended'' tests for confirming the impairment, 
at least one of the ``recommended'' tests should be positive.
    2.10  There are two categories of recommended tests which are 
described below.
    A. Imaging studies--These studies can include MRI, CAT scan, 
myelogram, or plain film x-rays. For conditions where several of 
these imaging studies are identified as ``recommended'' tests, at 
least one of the test results should be positive and meet the 
confirmatory test criteria. For some conditions, such as 
degenerative disc condition, there are several equivalent imaging 
methods to confirm a diagnosis.
    B. Other tests--This category of tests refers to non-imaging 
studies.
    2.11  If there are no ``highly recommended'' confirmatory tests 
designated to confirm an impairment and the ``recommended'' 
confirmatory tests only include non-imaging procedures, at least one 
of these tests should be positive to confirm the impairment. The 
greater the number of tests that are positive, the greater the 
confidence that the correct diagnosis has been established.
    2.12  Example: Under Body Part C., Cardiac, the diagnostic 
confirmatory tests for ventricular ectopy, a cardiac arrhythmia, 
include the following ``recommended'' tests:
    A. Medical record review, i.e., a review of the claimant's 
medical records, or
    B. Holter monitoring, or
    C. Provocative testing producing a definite arrhythmia.
    2.13  In this situation, only one of the ``recommended'' 
confirmatory tests need be positive to confirm the impairment. 
However, the more tests that are positive, the stronger the support 
for the diagnosis.
    2.14  In no circumstance will the Board require that an invasive 
test be performed to confirm an impairment. Several of the 
Confirmatory Tests which are described in the Tables are invasive 
and it is not the intention of the Board to suggest that these be 
performed. The inclusion of invasive tests in the Tables 
Confirmatory Tests section is intended to help the Board evaluate 
the significance of findings from such tests that may have already 
been performed and which are part of the submitted medical record.
    2.15  If an employee's impairment(s) cannot be confirmed by use 
of the confirmatory tests listed in the Tables, it still may be 
confirmed by medical evidence described in section 220.27 of this 
part. However, if a claimant's impairment(s) cannot be confirmed 
through use of the Tables or under section 220.27, and the medical 
evidence is complete and in concordance, the claimant will be found 
not disabled.

3. Disability Determination

    3.01  Once the Board determines that the employee's regular 
railroad occupation is covered by one of the Job Titles in the 
Tables and that his or her alleged impairment fits into a Body Part 
covered by the Tables and can be confirmed, we examine the results 
of any of the disability tests listed under the impairment. If the 
results from any of these tests indicate a ``D'' finding, the 
employee is found disabled. If none of the test results

[[Page 7544]]

indicate a ``D'' finding, then the employee's claim is evaluated 
using ICE.
    3.02  Example: A trainman has angina as confirmed by the 
recommended tests under Body Part A: Cardiac--Angina. An 
echocardiogram shows that he has poor ejection fraction 
<ls-thn-eq>35%. The employee is rated disabled. If none of the 
results of the listed disability tests match the results required 
for a ``D'' finding, then the employee's claim is evaluated under 
ICE.

A. Cancer

Cancer

    Cancer conditions can be viewed as belonging to one of three 
categories.
    Category 1: Significant impact on functional capacity or 
anticipated life span.
    Category 2: Intermediate impact on functional capacity; large 
individual variability.
    Category 3: No significant impact on functional capacity or 
expected life span.
    The factors that are considered in developing these categories 
include the following:

Type of Cancer

    The functional impact of different malignancies varies tremendously 
and each malignancy has to be considered on an individual basis.

Magnitude of Disease

    The disability standards are based upon the magnitude or extent of 
disease. The extent of disease affects both anticipated life span and 
the functional capacity or work ability of the individual. Localized 
cancer including cancer ``in situ'' can frequently be completely cured 
and not have an impact on functional capacity or life span. In 
contrast, many cancers that have distant or significant regional spread 
generally have a poor prognosis. The magnitude or extent of disease is 
classified into three categories: local, regional and distant.
    The criteria which are used to classify a cancer into one of the 
three categories are based upon the distillation of several staging 
methods into a single system [Miller, et al. (1992). Cancer Statistics 
Review, 1973 - 1989; NIH Publication No. 92 - 2789].

Effects of Treatment

    Although some types of cancer may be potentially curable with 
radical surgery and/or radiation therapy, the treatment regimen may 
result in a significant impairment that could affect functional 
capacity and ability to work. For example, a person with a laryngeal 
tumor which had spread regionally could be cured by a complete 
laryngectomy and radiotherapy. However, this treatment could result in 
a loss of speech and significantly impair the individual's 
communicative skills or ability to use certain types of respiratory 
protective equipment.

Prognosis

    Some cancers may have minimal impact on a person's functional 
capacity, but have a very poor prognosis with respect to life 
expectancy. For example, an individual with early stage brain cancer 
may be minimally impaired, but have a poor prognosis and minimal 
potential for surviving longer than two years. Five and two year 
survival data are presented in the Cancer Disability Guideline Table 
which follows.
    The Cancer Disability Guideline Table provides information 
concerning the probability of survival for five years for local, 
regional, and distant disease for each type of malignancy. In addition, 
two-year survival data are also presented for all disease stages. The 
five-year survival data are based upon data collected from population-
based registries in Connecticut, New Mexico, Utah, Hawaii, Atlanta, 
Detroit, Seattle and the San Francisco and East Bay area between 1983 
and 1987 (Miller, 1992). The two-year data are from a cohort study 
initially diagnosed in 1988.

Assessment

    The malignancies are classified as disabling (Category 1), 
potentially disabling (Category 2) and non-disabling (Category 3). 
Category 2 conditions must be evaluated with respect to how the 
worker's tumor affects the worker's ability to perform the job and an 
assessment of his life span.
    Information concerning the potential impact of the malignancy on a 
worker's ability to perform a job is identified in the Functional 
Impact column in the table. All railroad occupations in the Tables are 
considered together. Functional impacts are classified as significant 
if the treatment or sequelae from treatment including radiotherapy, 
chemotherapy and/or surgery is likely to impair the worker from 
performing the job. If the treatment results in a significant 
impairment of another organ system, the individual should be evaluated 
for disability associated with impairment of that body part. For 
example, a person undergoing an amputation for a bone malignancy would 
have to be evaluated for an amputation of that body part. For many 
cancers, it is difficult to make generalizations regarding the level of 
impairment that will occur after the person has initiated or completed 
treatment. Nonsignificant impacts include those that are unlikely to 
have any effect on the individual's work capacity.
