This is in the April Cutting Edge:
Screening-turned-diagnostic Colonoscopy,
Modifier 33, and Commercial Insurance
I read with interest Sarah W. Sebikari’s, MHA, CPC, article on coding
colorectal screening (“Consider All Factors when Coding Colonoscopies,”
October 2012, pages 26-28), and Kenneth D. Beckman’s, MD,
MBA, CPE, CPC, letter to the editor about personal history of colon polyps
(“Surveillance Colonoscopy Rules Differ from Pure Screenings,” December
2012, page 10). Thank you for both.
My question concerns patients with commercial insurance. When a patient
comes in for a colonoscopy with the diagnosis of personal history of colon
polyps, and if during this procedure a polyp is found, would it be appropriate
to list the diagnostic procedure code with modifier 33 Preventive services?
I ask because some commercial insurance companies list V12.72 Personal
history of colonic polyps under their preventive benefits.

"This is a complicated issue with many factors. The best advice is to look to
the carrier for guidance.
In many instances, commercial carriers will require modifier 33 and/or PT
Colorectal screening test converted to diagnostic test or other procedure to indicate
a procedure began as a preventive service, but resulted in a therapeutic
service (e.g., a screening colonoscopy resulted in a polypectomy). There
are several carriers, however, that do not recognize modifier PT and will instruct
you to use modifier 33 instead. There are also a few carriers who will
not recognize either modifier.
At my clinic, we have a list of our major carriers, noting their preference for
modifier 33 or PT use on a personal history diagnosis. Many commercial
carriers will not recognize V12.72 for a preventive service, and instead assign
this diagnosis for a surveillance (diagnostic) service, which would make
the use of either PT or 33 unnecessary. Medicare is the only insurer I am
aware of that processes surveillance and screening colonoscopies the same.
Let’s say, for example, the patient’s carrier is UnitedHealthcare® (UHC).
UHC’s modifier 33 policy is a great example of the direction most carriers
are going.
Per UHC’s policy, outlined in “Coverage Determination Guideline, Preventive
Care Services,” a coder should first determine whether the colonoscopy
is preventive (no symptoms, regular intervals, no personal history) or
diagnostic, which would include patients with a personal history of adenomatous
polyps who are undergoing surveillance at shortened intervals (five
versus 10 years). If the procedure starts out as preventive, and subsequently
converts to therapeutic due to a finding during the procedure, the coder
would use modifier 33.
The UHC policy states:
Modifier 33: UnitedHealthcare considers the procedures and
diagnostic codes and Claims Edit Criteria listed in the table below
in determining whether preventive care benefits apply. While
modifier 33 may be reported, it is not used in making preventive
care benefit determinations.
Fecal Occult Blood Testing, Sigmoidoscopy, or Colonoscopy:
Procedure Code(s):
Code Group 1: G0104, G0105, G0106, G0120, G0121, G0122,
G0328
Code Group 2: 44388, 44389, 44392, 44393, 44394, 45330,
45331, 45333, 45338, 45339, 45378, 45380, 45381, 45383,
45384, 45385, 82270, 82274, 88304, 88305
Diagnosis Code(s) (for Code Group 2): V16.0, V18.51, V18.59,
V70.0, V76.41, V76.50, V76.51
In other words, you would not use modifier 33 in this instance because
V12.72 is not a preventive diagnosis. Under UHC guidelines, this patient
would be undergoing a diagnostic (surveillance) procedure."
