Part A State Agency Date Change or Reply Record (RIC-D)

activein force · 2026-08-25 – presentas-observed

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.

The beneficiary HICN, a

nine-position numeric

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.

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.

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

a 10% surcharge for late

enrollment; otherwise, it

is blank.

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.

code that further defines

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.
