CMS Pub. 100-24, ch. 3, § 3.5.6
Part A State Agency Date Change or Reply Record (RIC-D)
All states receive date change records, but reply records are generated only for states
receiving daily response files. RIC-D reply records provide notification of actions that
will affect billing and are, therefore, considered a pre-billing notification.
Item Field Size Position Format Description
1 Medicare Number 12 1-12 Alpha-numeric
The beneficiary HICN, a
nine-position numeric
value followed by an
alpha-numeric BIC. If the
beneficiary is entitled
under a RRB claim
number, this field will
contain an 11-position
alpha-numeric pseudo
HICN. Positions 11 and
12 may be blank. This
field will convey the
Medicare number from
the EDB. CMS will not
return the MBI in this
state buy-in reply.

Part A Indicator
1 71 Numeric or
Alphabetic
When the transaction
code in position 77-78 is
“30,” this field will be
blank. For states
receiving daily files,
when the transaction
reply code is not “30,”
the presence of a “1” in
this position means the
reduced Part A premium
rate applies; otherwise, it
will be blank, unless the
state submitted a buy-in
eligibility code with their
Part A buy-in. If so, the
BIEC submitted for Part
A will be displayed.
9 Filler or Part A
Premium
Surcharge
Indicator
1 72 Numeric or
Blank
When the transaction
code in position 77-78 is
“30,” this field will be
blank. For states
receiving daily files,
when the transaction
reply code is not “30,”
the presence of a “1” in
this position means the
Part A premium includes
a 10% surcharge for late
enrollment; otherwise, it
is blank.

A three-position alpha-numeric code, beginning
with “S,” assigned to the

Item Field Size Position Format Description
11 Record
Identification Code
“D”
1 76 Alphabetic “D” constant. The “D”
identifies this record as a
date change record or,
for states receiving daily
response files, when the
transaction reply code is
not “30,” a reply record.
12 Transaction Code 4 77-80 Numeric A two- or four-position
numeric code. When
CMS must adjust the
effective date of an
incoming accretion
transaction to a later
date to conform to the
Medicare entitlement
date, the first two
positions contain the
value of “30.” The last
two positions will contain
the same transaction
code as was present on
the state input record.
For states receiving daily
response files, when the
transaction reply code is
not “30,” the first two
positions convey CMS'
reply to a state's
accretion or deletion
request. The last two
positions will contain the
same transaction code as
was present on the state
input record. For these
daily exchange states, the
two- or four-position
transaction code may
also convey that CMS
processed a debit or
credit billing action,
received from another
source, on behalf of the
state.
Item Field Size Position Format Description

1 81 Alphabetic A one-position alphabetic
code that further defines
the transaction code.

6 82-87 Numeric A six-position numeric
date field. When the
transaction reply code is
“30,” this field contains
the accretion transaction
effective date submitted
by the state, the date
which CMS adjusted to a
later date. The resulting
adjusted date is reflected
on an accompanying
billing record. For those
states receiving daily
files, when the
transaction reply code is
not “30,” this field
contains the beginning
date (year and month)
used in calculating a
refund or debit premium
amount for this
transaction reply. For
debits, the billing period
start date also represents
the applied transaction
effective date. For
credits, the transaction
effective date is
equivalent to the billing
period start date minus
one month. NOTE: the
billing period start and
stop dates are inclusive
dates.
Item Field Size Position Format Description

field that contains the
last date (year and
month) used in
calculating the refund or
premium amount for this

dates.
