CMS Pub. 100-04, ch. 18, § 60.1.1

There is no deductible and no coinsurance or copayment for the FOBTs (HCPCS G0107,

G0328), flexible sigmoidoscopies (G0104), colonoscopies on individuals at high risk (HCPCS

G0105), or colonoscopies on individuals not meeting criteria of high risk (HCPCS G0121).

Anesthesia services furnished in conjunction with and in support of a screening colonoscopy are

reported with CPT code 00812 and coinsurance and deductible are waived. When a screening

colonoscopy becomes a diagnostic colonoscopy, anesthesia services are reported with CPT code

00811 and with the -PT modifier; and the deductible is waived. Prior to January 1, 2022, when a

screening colonoscopy became a diagnostic, the beneficiary was liable for the full applicable

coinsurance. However, Section 122 of Division CC of the Consolidated Appropriations Act

(CAA) of 2021, Waiving Medicare Coinsurance for Certain Colorectal Cancer Screening Tests,

amended section 1833(a) of the Social Security Act to offer a special coinsurance rule for

screening flexible sigmoidoscopies and screening colonoscopies, regardless of the code that is

billed for the establishment of a diagnosis as a result of the test, or for the removal of tissue or

other matter or other procedure, that is furnished in connection with, as a result of, and in the

same clinical encounter as the colorectal cancer screening test. Consequently, the applicable

coinsurance in these specific scenarios will be gradually reduced until it is completely waived

for dates of service on or after January 1, 2030. Specifically, for dates of service in CY 2023

through CY 2026, when the PT modifier is appended to at least one code on the claim to

indicate that a screening colorectal cancer procedure, HCPCS G0104, G0105, or G0121, has

become a diagnostic or therapeutic service, contractors shall continue to waive deductible and

shall apply a reduced coinsurance of 15% for all procedure codes that meet the requirements

stated above and are performed on that date of service and billed on the same claim. For dates

of service in CY 2027 through CY 2029, contractors shall continue to waive deductible and

shall apply a reduced coinsurance of 10% for all procedure codes that meet the requirements

stated above and are performed on that date of service and billed on the same claim. For dates

of service on or after January 1, 2030, contractors shall continue to waive deductible and shall

waive coinsurance for all procedure codes that meet the requirements stated above and are

performed on that date of service and billed on the same claim.

Coinsurance and deductible are waived for moderate sedation services (reported with G0500 or

99153) when furnished in conjunction with and in support of a screening colonoscopy service

and when reported with modifier -33. When a screening colonoscopy becomes a diagnostic

colonoscopy, moderate sedation services (G0500 or 99153) are reported with only the -PT

modifier; only the deductible is waived.

Prior to January 1, 2007 deductible and coinsurance apply to other colorectal procedures

(HCPCS G0106 and G0120). After January 1, 2007, the deductible is waived for those tests.

Coinsurance applies.

Effective for claims with dates of service on and after October 9, 2014, deductible and

coinsurance do not apply to the Cologuard™ multi-target sDNA screening test (HCPCS G0464).

(Note: Beginning January 1, 2016, CPT code 81528 replaced G0464).

Effective for claims with dates of service on and after January 19, 2021, deductible and

coinsurance do not apply to the Blood-based biomarker test (HCPCS G0327).

Effective for claims with dates of service on or after January 1, 2023, colorectal cancer screening

tests include a screening colonoscopy (HCPCS codes G0105, G0121) that follows a non-invasive

stool- based test (HCPCS codes 82270, G0328 and 81528). This scenario shall be identified by the

furnishing practitioner by including the KX modifier on the screening colonoscopy claim. Deductible

and coinsurance do not apply to the non-invasive stool-based tests nor the screening colonoscopy

because both tests are specified preventive screening services.

NOTE: A 25% coinsurance applies for all colorectal cancer screening colonoscopies (HCPCS

G0105 and G0121) performed in ASCs and non-OPPS hospitals effective for services performed

on or after January 1, 2007. The 25% coinsurance was implemented in the OPPS PRICER for

OPPS hospitals effective for services performed on or after January 1, 1999.

A 25% coinsurance also applies for colorectal cancer screening sigmoidoscopies (HCPCS

G0104) performed in non-OPPS hospitals effective for services performed on or after January 1,

2007. Beginning January 1, 2008, colorectal cancer screening sigmoidoscopies (HCPCS G0104)

are payable in ASCs, and a 25% coinsurance applies. The 25% coinsurance for colorectal cancer

screening sigmoidoscopies was implemented in the OPPS PRICER for OPPS hospitals effective

for services performed on or after January 1, 1999.

Effective for claims with dates of service on or after January 1, 2011, coinsurance and

deductible do not apply to screening colonoscopies, screening sigmoidoscopies, and other

specified colorectal cancer screening services.
