Abstract:
Dermal-epidermal tissue (DET) substitute (e.g., Apligraf ®) is a bi-layered
skin product approved for use in the treatment of non-infected partial and
full-thickness skin ulcers due to venous insufficiency, i.e., venous stasis
ulcers (VSUs), and full thickness neuropathic diabetic foot ulcers (DFUs).
Apligraf ® is manufactured from a living neonatal male foreskin and it
consists of two primary layers: the epidermal layer is formed by human
keratinocytes and has a well-differentiated stratum corneum; the dermal
layer is composed of human fibroblasts in a bovine Type I collagen lattice.
For the purpose of this article, re-application is referring to an additional
application of skin substitutes to the same ulcer within the same treatment
period. Retreatment is referencing a new treatment period where the same
ulcer is being treated again because the initial treatment has most likely
failed.
Indications
Apligraf ® will be considered reasonable and necessary when the following
conditions are satisfied and documented:
When used with standard therapeutic compression for VSUs:
- Only for
ulcers that have failed to respond to documented conservative measures
of greater than six (6) weeks in duration, that have at minimum
included regular dressing changes, debridement of necrotic tissue and
standard therapeutic compression. A "failed response" is
defined as an ulcer that has increased in size or depth, or for which
there has been no change in baseline size or depth and no sign of
improvement or indication that improvement is likely, such as
granulation, epithelialization, or progress towards closing.
Documentation of response, or lack thereof, requires measurement of
the ulcer at baseline, following cessation of conservative or
conventional management. Documentation should also include measurement
of the ulcer immediately prior to the placement of Apligraf ®.
- Only when adequate treatment of
the underlying disease process(es) contributing to the ulcer, e.g.
hypertension, is provided and documented in conjunction with the
treatment; and
- Only for
ulcers that are free of infection, redness, drainage, underlying
osteomyelitis, surround cellulitis, sinus tracts or tunnels, eschar or
any necrotic material that could interfere with the adherence of
Apligraf ® and wound healing.
When
used with standard diabetic foot ulcer care for neuropathic DFUs:
- Only if the
patient has the current medical diagnosis of either Type I or Type II
diabetes mellitus;
- Only if the patient does not
have a current HbA1C reading exceeding 12%;
- Only for full thickness ulcers
of greater than three weeks in duration, which extend through the
dermis but without tendon, muscle, capsule or bone exposure;
- Only when adequate treatment
of the underlying disease process(es) contributing to the ulcer, e.g.,
diabetes is provided and documented in conjunction with treatment; and
- Only for
ulcers located on the foot or toes that are free of infection,
redness, drainage, underlying osteomyelitis, surrounding cellulitis,
tunnels and tracts, eschar or any necrotic material that could
interfere with the adherence of Apligraf ®, and the process of wound
healing.
For both VSUs and DFUs all of the
following must also be satisfied and documented:
- The patient
must have adequate arterial blood supply as evidenced by
ankle-brachial index (ABI) of 0.65 or greater in limb undergoing the
procedure;
- DET
treatment must be used in conjunction with following standard
conservative measures:
- Use
of pressure-reducing footwear;
- A
non-weight bearing regiment;
- Debridement
of necrotic and callused tissue when necessary; and
- Acceptable
methods of wound care, such as saline moistened dressings
- The patient
must be competent and/or have the support system required to
participate in follow-up care associated with treatment of the wound
with Apligraf ®.
Limitations
The use of Apligraf ® on ulcers with any of the following conditions is
considered not necessary and reasonable, and will result in denial of a
claim:
- cellulitis;
- osteomyelitis;
- necrotic ulcer;
- draining wound;
- bone exposed- wound bed; or
- clinically
significant wound healing impairment due to uncontrolled diabetes.
Apligraf ® is contraindicated for
use in patients with known allergy or hypersensitivity to bovine collagen,
or to the components of the Apligraf ® agarose shipping medium, (agarose,
L-glutamine, hydrocortisone/bovine serum albumin, bovine insulin, human transferrin,
triiodothyronine, ethanolamine, O-phosphorylethanolamine, adenine,
selenious acid, DMEM powder, HAM's F-12 powder, sodium bicarbonate, calcium
chloride, and water for injection. In vitro and in vivo histology studies
have shown that Apligraf ® either degrades or its cell viability is reduced
when the device is exposed to the following cytotoxic agents: Dakin's
solution, Mafenide acetate, Scarlet red dressing, Tincoban, Zinc sulfate,
Povidone-iodine solution, Chlorhexidine, or Polymixin/Nystatin. The use of
Apligraf ® with these solutions will be considered not reasonable and
necessary, and will result in denial of reimbursement.
The scope of the practice for Podiatry is defined by state law and the
individual state laws should be consulted in determining a specific
podiatrist’s (or doctor of podiatric medicine) scope of practice.

Utilization Guidelines
- A single
application of DET for any particular ulcer is usually all that is
required to affect wound healing in those wounds that are likely to be
helped by this therapy. Treatment with Apligraf ® is usually expected
to last no more than twelve (12) weeks and to involve a maximum of
four Apligraf ® applications for any ulcer that initially qualifies
for treatment. The use of more than four applications for the same
ulcer is not considered reasonable and necessary and will not be
reimbursed.
- Re-application of Apligraf ®
within three weeks for the same ulcer is not considered reasonable and
necessary and will not be reimbursed.
- Re-application of Apligraf ®
where initial application has resulted in no decrease in size or depth
or increase in granulation tissue, epithelialization, or progress
towards closing, will be denied as not reasonable and necessary and
will not be reimbursed.
- Re-treatment within one year
following the last successful application with DET is not considered
reasonable and necessary, and will not be reimbursed.
- Retreatment of an ulcer
following the unsuccessful treatment where it consisted of two failed
Apligraf ® applications is not considered reasonable and necessary,
and will not be reimbursed.
- These codes
are not intended to be reported for simple graft application alone or
application stabilized with dressings (eg, by simple gauze wrap). The
skin substitute/graft is anchored using the surgeon's choice of
fixation. (CPT 2007). If it is not medically reasonable
and necessary to anchor the Apligraf ®, (for example, due to size,
depth or location of the wound), then the application is included in
the appropriate E&M code and should not be submitted with the
application codes.
Coding Guidelines
Payable places of service for the application of Apligraf : office (11),
inpatient hospital (21), outpatient hospital (22), hospital emergency room
(23), ambulatory surgical center (24), Skilled Nursing Facility (31),
Nursing Facility (32) and independent clinic (49).
ICD-9-CM codes 707.12, 707.13, 707.14 and 707.15
must be billed with a Diabetes ICD-9-CM code listed as the primary
diagnosis.
