31, 2008 consolidated financial statements were free from material misstatement,
the Company performed alternative procedures during the course of preparing the
December 31, 2008 consolidated financial statements.&#160;&#160;These
alternative procedures performed by management included: 1) a detailed manual
review of the aging of accounts receivables, 2) the write-off of all accounts
over 270 days old, 3) establishment of additional methodologies to better
estimate the allowances for provider discounts (as more fully described in our
response to Staff&#8217;s comment number 9), and 4) a line-by-line review of all
purchased inventory items to correct, where needed, to current year costs of
items purchased and items which were manufactured.</font></div>

&#8220;provision for provider discounts&#8221;. When preparing the 2008 comparative
consolidated financial statements for the year ended December 31, 2008, the
Company utilized the 2007 Statement of Cash Flows as originally filed and
inadvertently did not break out the 2007 provision amount separately into these
two components. There was no effect on the total of the two provisions. The
Company believes there is not a material impact to readers of the financial
statements as there is no impact on the &#8220;net cash provided by operating
activities&#8221; in the Statement of Cash Flows and that a reader of the financial
statements would not have formed a different opinion had the amount been
presented separately. The properly classified amounts for 2007 were $4,462,724
for the provision for provider discounts and $339,000 for the provision for
uncollectibility. The Company intends to break out the components described
above in future filings for all periods presented.</font></div>

Company recognizes revenue upon shipment to distributors and transfer of title,
because the Company believes the four requirements for recognizing revenue have
been met. Specifically, evidence of an arrangement exists in the form of the
order from the distributor, delivery exists because the products have been
shipped to the distributor and title has transferred, there is a fixed sales
price based on the order from the distributor and, collectability is reasonably
assured based on the Company&#8217;s collection history with the distributors and the
assessed credit worthiness of the distributors with which the Company does
business. Sales to distributors were less than 0.5% of the Company&#8217;s total
revenue in 2008.</font></div>

from paragraph 1.28. Some third-party payors retrospectively determine final
amounts reimbursable for services rendered to their beneficiaries based on
allowable costs. These payors reimburse the health care organization on the
basis of interim payment rates until the retrospective determination of
allowable costs can be made. In most instances, the accumulation and allocation
of allowable costs and other factors result in final settlements different from
the interim payment rates. Final settlements are determined after the close of
the fiscal periods to which they apply and may affect materially the health care
organization's financial position and results of operations. Consequently, a
reasonable estimate of the amount receivable from or payable to these payors
should be made in the same period that the related services are
rendered.</font></div>

services usually are recorded in the accounting records on an accrual basis at
