As I said in my posting last Saturday with regard to making public
providers' bank account and ABA routing numbers, some "liaisoning" with
X12F Finance and NACHA might be in order.

So I did just that: some "liaisoning."  I corresponded with both Richard
Bort, a certified cash manager and financial consultant specializing in
treasury management and electronic commerce, and the author of the
classic reference "Corporate Cash Management Handbook;" and Priscilla
Holland, Senior Director, International & Corporate Payments, at NACHA.
I just love "liaisoning" and name-dropping - it beats real work any day.

Both Bort and Holland agree that it would be none too wise to post
account information (like the routing number and bank account number) in
a public registry with no controls to limit access.  They've graciously
allowed me to share their remarks.

   As for the issue at hand, it highlights a conflict between
   reason and emotion, with a large dollop of fraud thrown in.

   Of course everyone to whom we write checks can know our bank
   transit routing number and account number. By the same token,
   we wouldn't plaster those numbers on a billboard alongside
   the highway (or in a publicly-accessible directory on the Web),
   though, for fear that some miscreant would misuse that
   information. I know what you're thinking: "In Europe they print
   their bank IDs and account numbers on their invoices to
   facilitate remittances, so why don't we do it?"

   The largest source of bank fraud in the U.S. is check fraud,
   most of which involves the creation of totally bogus checks
   using a PC and a laser printer. If I know the bank and account
   numbers of a deep-pocketed firm, like a hospital, I could make
   up a check (or, preferably, a series of modest size checks)
   purportedly drawn against that bank account and probably get
   away with it. The banking industry has created some effective
   defenses against this (e.g., "Positive Pay" service) but losses
   continue to be heavy. Therefore, it's just not wise to
   advertise one's bank account number to anyone who may be
   interested. (BTW, the bogus check need not have the MICR line
   printed in magnetic ink. The banks, "los brilliantes" that they
   are, will kindly repair unreadable MICR numbers with a readable
   strip pasted to the bottom of a check.)

   In the healthcare business, there are relatively few payers
   (hundreds, or maybe a thousand or so, but not an entire
   boatload). I see no reason why there could not be some central
   registry to which legitimate payers could gain controlled
   access. That registry could/should contain more than just the
   depository bank account numbers. It probably should also
   include a profile of the provider, such as preferred way to
   receive remittances (e.g., EFT/EDI, together or separated, check
   in the mail, etc. etc., and a contact person and phone number
   and e-mail address).

   There are just too many bad guys around who would really mess
   things up if we were to publicy post bank account numbers. It's
   that simple. I hope this is helpful.

Priscilla adds:

   As far as publishing your account number - the biggest issue
   is fraud. NACHA has historically published information on all
   conference brochures on how to make an electronic payment for
   the conference registration and have published the routing &
   transit number and account number for our primary checking
   account (not a good idea).  Last year we had 17 unauthorized
   debits to that account.  It seems that the criminals are
   learning about the capabilities of ACH fraudulent debits.  If
   you want to publish an account on the web - I would suggest
   that it be set with a debit block - that will prevent
   unauthorized debits - and the account be monitored very
   closely. [The Columbus Dispatch article] talks about finding
   additional funds as a windfall - finding that your account has
   no money because of unauthorized debits would be somewhat more
   likely. If you want to publish your account information - it
   would probably be better to have a separate account for this
   purpose and then transfer the funds into the general account.

I think this settles the matter, though it's disappointing that banking
account "security" relies on keeping these identifiers semi-secret.

Perhaps we can accommodate protection of the financial account
information in the directory some technical way to ensure it is revealed
only to legitimate payers (insurance companies) - by restricting it to
only those folks who possess a directory entry themselves or somesuch
nonsense.  Or the 837 claim could be changed to send the provider's
routing and account numbers for EFT payments directly to the payer (I
was surprised it wasn't there already), bypassing the Healthcare CPP
directory altogether.
