1.
QualChoice considers Growth Hormone replacement medically necessary for children
and adolescents (prior to epiphyseal fusion)
after an evaluation by a pediatric endocrinologist
(or pediatric nephrologist, in the case of chronic renal failure), when
prescribed for one of the following indications:
-
Idiopathic Growth
Hormone Deficiency (E23.0) (All of the following):
-
Has failed to
respond to at least two standard GH stimulation tests, defined as a
serum GH level (peak level) of less than 10 nanograms per milliliter
(ng/ml), after stimulation with insulin, levodopa, arginine,
propranolol, clonidine, or glucagon. (However, one abnormal GH test
is sufficient for children with defined CNS pathology, history of
irradiation, multiple pituitary hormone deficiency (MPHD) or a
genetic defect affecting the GH axis); and
-
Appropriate
imaging (magnetic resonance imaging (MRI) or computed tomography
(CT)) of the brain with particular attention to the
hypothalamic-pituitary region has been carried out to exclude the
possibility of a tumor; and
-
At least one
of the following criteria is met:
·
Child has
severe growth retardation with height at least 3 standard deviations below the
mean for chronological age and sex; or
·
Child has
moderate growth retardation with height between 2 and 3 standard deviations
below the mean for chronological age and sex and decreased growth rate
(growth velocity (GV) measured over one year below 25th percentile for age and
sex); or
·
Child
exhibits severe deceleration in growth rate ((GV)measured over 1 year 2 standard
deviations below the mean for age and sex); or
·
Child has
decreasing growth rate combined with a predisposing condition such as previous
cranial irradiation or tumor; or
·
Child
exhibits evidence of other pituitary hormone deficiencies or signs of congenital
GHD (hypoglycemia, microphallus); and
-
Evaluation of
bone age demonstrates open epiphyses.
-
For persons
with thyroid deficiency, QualChoice only accepts results of GH
secretion tests that are performed after thyroid deficiency is
adequately treated because GH secretion may be subnormal merely as a
result of hypothyroidism.
-
Chronic Renal
Insufficiency (N18.1 – N18.9):
Prior to renal
transplantation GH Replacement is considered medically necessary for
children with chronic renal insufficiency and growth retardation who
meet all of the following criteria:
-
Child`s
nutritional status has been optimized, metabolic abnormalities have
been corrected, and steroid usage has been reduced to a minimum;
and
-
At least one
of the following criteria is met:
-
Child has
severe growth retardation with height below 3 standard
deviations below the mean for chronological age and sex; or
-
Child has
moderate growth retardation with height between 2 and 3 standard
deviations below the mean for chronological age and sex and
decreased growth rate (GV measured over one year below 25th
percentile for age and sex); or
-
Child
exhibits severe deceleration in growth rate (GV measured over
one year at least 2 standard deviations below the mean for age
and sex); and
-
Evaluation of
bone age demonstrates open epiphyses.
-
Note:
Consistent with established guidelines for children with chronic
renal insufficiency after renal transplantation, QualChoice does not
consider resumption of growth hormone therapy medically necessary
until at least 1 year after the transplant to allow time to
ascertain whether catch-up growth will occur.
-
Turner`s Syndrome
(Q96.0-Q96.9):
QualChoice
considers GH replacement medically necessary for children with Turner`s
syndrome and growth retardation who meet all of the following
criteria:
-
The diagnosis
of Turner`s syndrome is confirmed by chromosome analysis; and
-
At least one
of the following criteria is met:
-
Child has
severe growth retardation with height at least 3 standard
deviations below the mean for chronological age and sex; or
-
Child has
moderate growth retardation with height between 2 and 3 standard
deviations below the mean for chronological age and sex and
decreased growth rate (GV measured over one year below 25th
percentile for age and sex); or
-
Child
exhibits severe deceleration in growth rate (GV measured over
one year is at least 2 standard deviations below the mean for
age and sex).
-
Prader Willi
Syndrome (Q87.1):
QualChoice considers GH replacement medically necessary for children
with Prader Willi syndrome and growth retardation who meet all of
the following criteria:
-

moderate growth retardation with height between 2 and 3 standard
deviations below the mean for chronological age and sex and
decreased growth rate (GV measured over one year below 25th
percentile for age and sex); or
-
Child
exhibits severe deceleration in growth rate (GV measured over
one year is at least 2 standard deviations below the mean for
age and sex).
-
Small for
Gestational Age (SGA) Children (P05.00 – P05.18):
QualChoice considers growth hormone supplementation medically necessary for
children born small for gestational age, and who meet both these criteria:
-
Child was
born small for gestational age, defined as birth weight or length 2
or more standard deviations below the mean for gestational age; and
-
Child fails
to manifest catch up growth by age 3 years, defined as height 2 or
more standard deviations below the mean for age and sex.
2. Discontinuation of GH therapy: Re-evaluation at least annually by the
prescribing specialist will be required for continuation of therapy. In children
and adolescents, GH therapy will be considered not medically necessary if any of
the following discontinuation criteria is met:
a.
Increase in
height velocity is less than 2 cm total growth in one year of therapy; or
b.
Expected
final adult height has been reached; or
c.
Epiphyses are closed on re-evaluation; or
d.
If there is
a poor response to treatment, generally defined as an increase in growth
velocity of less than 50% from baseline, in the first year of therapy. In
children with Prader-Willi Syndrome, evaluation of response to therapy should
also take into account whether body composition (i.e., ratio of lean to fat
mass) has significantly improved; or
e.
There are
persistent and uncorrectable problems with adherence to treatment.
f.
Treatment
goals have been met.
3. Growth Hormone
Deficiency in Adults: GH replacement is considered medically necessary for
adults who meet the following criteria:
a.
Destructive lesions of the pituitary (D44.3):
GH treatment of adults with laboratory documented
GHD is considered medically necessary when all of the following criteria
are met:
i.
Member has
GH deficiency as a result of hypothalamic or pituitary disease (e.g.,
panhypopituitarism, pituitary adenoma, trauma, cranial irradiation, pituitary
surgery) and at least one other hormone deficiency diagnosed (except for
prolactin deficiency); and
ii.
Member is
already receiving adequate replacement therapy for any other pituitary hormone
deficiencies; and
iii.
Member has
a severe GH deficiency, defined as a peak GH response of less than 9 mU/liter (3
ng/ml) during an insulin tolerance test or a cross-validated GH threshold in an
equivalent test (growth hormone releasing hormone, arginine, or glucagon);
and
iv.
Member has
a perceived impairment of quality of life (QoL), as demonstrated by a reported
score of at least 11 in the disease-specific `Quality of life assessment of
growth hormone deficiency in adults` (QoL-AGHDA) questionnaire see figure 1
below.
This treatment is
considered medically necessary for an initial 9 months, allowing for an initial
3-month period of GH dose titration, followed by a 6-month therapeutic trial
period. Subsequent GH treatment is considered medically necessary only if, upon
subsequent testing of the effect of this treatment, the member demonstrates a
QoL improvement of 7 or more points in QoL-AGHDA score (see Figure 1 below).
b.
Adults who were growth hormone deficient as children or adolescents (E23.0):
i.
For
adolescents and adults younger than age 25 years with childhood-onset growth
hormone deficiency (including idiopathic isolated growth hormone deficiency
(IIGHD) or multiple pituitary hormone deficiencies, including growth hormone
(MPHD)) who have completed linear growth (growth rate less than 2 cm per year),
GH treatment at adult doses is considered medically necessary only :
·
In those
who have failed to respond to at least two standard GH stimulation tests,
defined as a peak GH response of less than 9 mU/liter (3 ng/ml) during an
insulin tolerance test and one other cross-validated GH test (growth hormone
releasing hormone, arginine, or glucagon).
·
For adults
having a low IGF-1 (a marker of insulin response) concentration (standard
deviation score less than -2), failure to respond to only one standard GH
stimulation test is required. In these members, GH supplementation at adult
doses is considered medically necessary until adult peak bone mass is achieved
(between 25 and 30 years of age).
Note:
Continued authorization of GH therapy at adult doses, will be approved provided
that GH therapy be stopped for at least 3 months after completion of linear
growth (that is, growth rate less than 2 cm/year), and that GH status is
reassessed. As a condition of continued authorization, QualChoice requires
reassessment of GH status after GH treatment is stopped for at least 3 months
before initiating GH supplementation at adult doses. QualChoice will reevaluate
the member three or more months after discontinuation of GH therapy to determine
if the member fulfills medical necessity criteria for GH treatment at adult
doses.
ii.
For adults
over age 25 years with childhood onset growth hormone deficiency (IIGHD or
MPHD), GH treatment at adult doses is considered medically necessary if they
meet all of the following criteria:
·
Member has
failed to respond to at least two standard GH stimulation tests, defined as a
peak GH response of less than 9 mU/liter (3 ng/ml) during an insulin tolerance
test and one other cross-validated GH test (growth hormone releasing hormone,
arginine, or glucagon). For members having a low IGF-1 (a marker of insulin
response) concentrations (SDS less than -2), failure to respond to only one
standard GH stimulation test is required; and
·
Member has
a perceived impairment of quality of life (QoL), as demonstrated by a reported
score of at least 11 in the disease-specific `Quality of life assessment of
growth hormone deficiency in adults` (QoL-AGHDA) questionnaire (see Figure 4
below).
iii.
Adults who develop growth hormone deficiency in early adulthood (E23.0): GH treatment at adult doses is considered
medically necessary for selected members who develop isolated GH deficiency
(IIGHD or MPHD) in adolescence or early adulthood, after linear growth is
completed but before the age of 25 years. GH treatment at adult doses is
considered medically necessary only in those who have failed to respond to at
least two standard GH stimulation tests, defined as a peak GH response of less
than 9 mU/liter (3 ng/ml) during an insulin tolerance test and one other
cross-validated GH test (growth hormone releasing hormone, arginine, or
glucagon). For adults having a low IGF-1 (a marker of insulin response)
concentration (SDS less than -2), failure to respond to only one standard GH
stimulation test is required. In these members, GH supplementation at adult
doses is considered medically necessary until adult peak bone mass is achieved
(between 25 and 30 years of age).
iv.
Following
achievement of peak bone mass between 25 and 30 years of age, continued GH
treatment is considered medically necessary for adults who meet both
of the following criteria:
·
Member has
a severe GH deficiency: GH treatment at adult doses is considered medically
necessary only in those who have failed to respond to at least two standard GH
stimulation tests, defined as a peak GH response of less than 9 mU/liter (3 ng/ml)
during an insulin tolerance test and one other cross-validated GH test (growth
hormone releasing hormone, arginine, or glucagon). (For adults having a low
IGF-1 (a marker of insulin response) concentration (SDS less than -2), failure
to respond to only one standard GH stimulation test is required); and
·
Member has
a perceived impairment of quality of life (QoL), as demonstrated by a reported
score of at least 11 in the disease-specific `Quality of life assessment of
growth hormone deficiency in adults` (QoL-AGHDA) questionnaire (see Figure 1
below).
c.
AIDS-related Wasting (B20 w/also R64): QualChoice considers GH supplementation to be
medically necessary for HIV-infected persons with involuntary weight loss of
greater than 10% of pre-illness baseline body weight or body mass index (BMI)
less than 20 kg/m2, in the absence of a concurrent illness or medical
condition other than HIV infection that would explain these findings, and who
have failed to adequately respond or are intolerant to anabolic steroids (e.g.,
Megace).
d.
Dosage: According to available guidelines, for the first
2-3 months dosage adjustments should be made after monthly assessments of serum
levels of IGF-1, and in response to the presence of adverse effects, until a
maintenance dose is achieved. As a condition of continued authorization,
QualChoice requires at least annual reassessment of serum levels of IGF-1 in
adults and appropriate dosage adjustments, as GH requirements in adults may
decrease with age.
e.
Continued Authorization:
The continued medical necessity of growth hormone therapy is reviewed at least
annually to determine whether growth hormone therapy continues to be medically
necessary. The annual medical necessity review focuses on response to therapy,
whether discontinuation criteria are met, whether there are any major changes in
clinical status affecting the medical necessity of growth hormone
supplementation, and verification that the person continues to follow up with
the provider and receive appropriate reevaluations and care.
f.
Growth
Hormone for Short Bowel Syndrome:
QualChoice considers GH supplementation to be medically necessary for persons
with short bowel syndrome who depend on intravenous parenteral nutrition for
nutritional support. Growth hormone treatment of short bowel syndrome for more
than four weeks duration is considered experimental and investigational as
administration of growth hormone for more than four weeks duration has not been
adequately studied for this indication. There is insufficient evidence of the
effectiveness of repeat courses of growth hormone for short bowel syndrome.
g.
Contraindications:
Growth hormone therapy is considered experimental and investigational in persons
with any of the following contraindications for which the safety of growth
hormone therapy has not been established:
i.
Persons
with evidence of tumor activity. In persons with tumors, anti-tumor therapy must
be completed before initiating growth hormone therapy; or
ii.
Critically
ill persons (e.g.,, after complications following open heart or abdominal
surgery, multiple trauma, acute respiratory failure or similar conditions);
or
iii.
Persons
with known hypersensitivity to growth hormone or to any of its excipients; or
iv.
Benign
intracranial hypertension (BIH); or
v.
Diabetic
retinopathy; or
vi.
Women who
are pregnant or lactating.
