Medicare Summary Notice (MSN) Messages
The following Medicare Summary Notice (MSN) messages are used (See Chapter 21 for the

being denied because of the age of the beneficiary, use:
18.29 - This service is not covered for people under 45 years of age.
Spanish Version- “Este servicio no está cubierto para las personas menores de 45 años.”
B. If the claim for a screening FOBT, a screening colonoscopy, a screening flexible
sigmoidoscopy, or a barium enema is being denied because the time period between the same
test or procedure has not passed, use:
18.14 - Service is being denied because it has not been (12, 24, 48, 120) months since your
last (test/procedure) of this kind.
C. If the claim is being denied for a screening colonoscopy or a barium enema because the
beneficiary is not at a high risk, use:
18.15 - Medicare covers this procedure only for people considered to be at a high risk
for colorectal cancer.

screening colonoscopy (HCPCS G0105), or a screening barium enema (HCPCS G0106 or
G0120), use:
18.16 - This service is denied because payment has already been made for a similar
procedure within a set timeframe.

performed as an alternative to another screening procedure. For example: If the claims history
indicates a payment has been made for HCPCS G0120 and an incoming claim is submitted for
