G0104 - Colorectal Cancer Screening; Flexible Sigmoidoscopy
Screening flexible sigmoidoscopies (code G0104) may be paid for beneficiaries who have attained age 50, when performed by a doctor of medicine or osteopathy at the frequencies noted below.
For claims with dates of service on or after January 1, 2002, contractors or carriers pay for screening flexible sigmoidoscopies (code G0104) for beneficiaries who have attained age 50 when these services were performed by a doctor of medicine or osteopathy, or by a physician assistant, nurse practitioner, or clinical nurse specialist (as defined in §1861(aa) (5) of the Act and in the Code of Federal Regulations at 42 CFR 410.74, 410.75, and 410.76) at the frequencies noted. For claims with dates of service prior to January 1, 2002, contractors pay for these services under the conditions noted only when a doctor of medicine or osteopathy performs them.
For services furnished from January 1, 1998, through June 30, 2001, inclusive:
- Once every 48 months (i.e., at least 47 months have passed following the month in which the last covered screening flexible sigmoidoscopy was done)
For services furnished on or after July 1, 2001: :
- Once every 48 months as calculated above unless the beneficiary does not meet the criteria for high risk of developing colorectal cancer and he/she has had a screening colonoscopy (code G0121) within the preceding 10 years. If such a beneficiary has had a screening colonoscopy within the preceding 10 years, then he or she can have covered a screening flexible sigmoidoscopy only after at least 119 months have passed following the month that he/she received the screening colonoscopy (code G0121).
NOTE: If during the course of a screening flexible sigmoidoscopy a lesion or growth is detected which results in a biopsy or removal of the growth; the appropriate diagnostic procedure classified as a flexible sigmoidoscopy with biopsy or removal should be billed and paid rather than code G0104.
