Rating Schedule

SECTION 12: DIGESTIVE SYSTEM

INTRODUCTION

For the purposes of determining impairment due to disorders of the upper digestive tract, “desirable” weight may be defined as follows:

A. If the examiner is able to determine by history or from previous medical records a weight before onset of the patient’s digestive illness that he or she considers “usual,” the examiner should use that weight as the “desirable” weight from which any deviations are measured.

B. If the examiner is not able to determine by history or from previous medical records a pre-illness “usual” weight, the examiner should refer to a table of “desirable” weights and should determine deviations from the lower end of the range of the “desirable” weight for the patient’s sex, height, and body build. Table 1, which is based on the 1979 Body Build Study by the Society of Actuaries and Association of Life Insurance Medical Directors of America, is recommended.

For an obese patient, the pre-illness weight may not be as physiologically “desirable” as the present weight; thus, the examiner should use judgment in assessing the relative importance of weight loss in determining the impairment rating.

In most cases, the examiner should use the definition shown under A. The definition and reference in B will be helpful if A cannot be used.

NOTE: The individual with a solitary kidney, regardless of cause, should be rated as having 10% impairment of the whole person. This value is to be combined with any other permanent impairment (including any impairment in the remaining kidney) pertinent to the case under consideration. The normal ranges of creatinine clearance are: Males: 130 to 200 liters/24 hr (90 to 139 ml/min.), Females: 115 to 180 liters/24 hr (80 to 125 ml/min.). The normal PSP excretion is 25% or more in urine in 15 minutes.

URINARY DIVERSION

Permanent, surgically created forms of urinary diversion usually are provided to compensate for anatomic loss and to allow for egress of urine. They are evaluated as a part of, and in conjunction with, the assessment of the involved portion of the urinary tract.

Irrespective of how well these diversions function in the preservation of renal integrity and the disposition of urine, the following values for the diversions should be combined with those determined under the criteria previously given for the portion of the urinary tract involved.

Type of Diversion

% Impairment of the Whole Person

Cutaneous Ureterostomy

10%

Nephrostomy or Intubated Ureterostomy

15%

Cystectomy with Urinary Diversion

A person belongs in Class 1 when the patient has symptoms and signs of bladder disorder requiring intermittent treatment with normal function between episodes of malfunction.

A patient belongs in Class 1 when symptoms and signs of urethral disorder are present that require intermittent therapy for control.

Class 2—Impairment of the Whole Person, 10—20%

MALE REPRODUCTIVE ORGANS

The male reproductive organs include the penis, scrotum, testes, epididymides, spermatic cords, prostate, and seminal vesicles. The values of impairment of the male reproductive organs are given in the following sections for men 40-65 years of age. These values may be increased by 25% of a given value for those below the age of 40 years, and decreased by 25% for those over the age of 65 years. For instance, a 25% increase of a 20% impairment equals 25% impairment.

Penis

When evaluating impairment of the penis, it is necessary to consider impairment of both the sexual and the urinary functions. The degree of impairment of sexual function should be determined in accordance with the criteria that follow, and it should be combined with the appropriate value for an impairment of urinary function that is present to determine the impairment of the whole person.

Class 1—Impairment of the Whole Person, 1—9%
