Because gastrointestinal endoscopy procedures have a global period of zero days, a gastroenterologist can bill for a follow-up office visit on a subsequent day, says Joel Brill, MD, a gastroenterologist in Phoenix and the American Gastroenterology Association's representative to the CPT Editorial Advisory Committee. The visit will probably be an established patient office visit (99211-99215) because the patient has previously received professional services from the gastroenterologist. With procedures such as an esophageal motility study or 24-hour pH monitoring, where the physician or another provider may have performed the test, the gastroenterologist may still bill a follow-up visit when discussing the test results with the patient as long it meets the requirements of an E/M service.
Two sets of E/M guidelines followed by both CPT and Medicare apply to follow-up visits. The first is that for an established patient office visit, two of the following three key components must be present during the encounter: history, examination and medical decision-making. The other guideline is that when counseling and coordination of care dominates more than 50 percent of the physician/patient encounter, time may be considered the key or controlling factor in choosing a particular level of E/M services rather than the level of history, examination and medical decision-making.
"Even if the visit is primarily for counseling and coordination of care, you can't throw out history, examination and medical decision-making," says Catherine Brink, CMM, CPC, president of Healthcare Resource Management Inc., a physician practice management consulting firm in Spring Lake, N.J. "You can't just write 'spent 35 minutes -- 20 minutes counseling patient' on the medical record. The auditor needs to know what you did for the other 15 minutes of the visit."
Brink recalls a chart she recently reviewed for a colonoscopy follow-up visit. The gastroenterologist's office had called the patient to say that there were no polyps, but she did have diverticulosis. The patient was asked to come into the office to discuss the results of the colonoscopy. "The note in the chart read 'Diverticulosis discussed. Long conversation ensued. Doesn't have to come back for five years,'" Brink says. "But there was no history, no exam and no diagnosis noted."
After a reason for the visit has been established and documented, the gastroenterologist must document the medical necessity for the visit. Though the follow-up visit may consist primarily of reviewing test or endoscopy results and discussing treatment options, both Brink and Brill believe that most gastroenterologists are also taking some history information and performing some examination and medical decision-making services during those encounters. The key is to document what is going on during the visit. Because these are usually established patient visits, however, only two of the three components need to be considered.
If the patient's condition has not changed since the last visit, the phrase "No changes since last visit on May 1" is appropriate to qualify as history. Other items that may be part of the interval history include the patient's reactions to any medications taken, any new symptoms, a change in diet, or any changes in old symptoms.
Brink stresses that even though the nurse may take the patient's vital signs, the gastroenterologist must document that he or she reviewed those vital signs with a phrase such as "Vital signs reviewed as noted."
The examination during a follow-up visit will also be brief and probably limited. The standard practice with most gastroenterologists is that their nurse will take a patient's vital signs before the gastroenterologist sees the patient even for a follow-up visit, according to Brill. "A nurse will do a blood pressure check, take a pulse and the patient's weight," he explains. "These are physical findings even if the gastroenterologist never lays a hand on the patient during that visit, you still have documented physical exam findings."
In most follow-up visits, the diagnosis and plan of treatment are part of the medical decision-making for that encounter. For example, in the case of the patient with diverticulosis, the gastroenterologist may decide that the patient only needs a change of diet or may decide that the patient needs medication. Both options are considered medical decision-making, according to Brink, and the gastroenterologist should outline what treatment is prescribed.
He suggests that in the case of the patient with diverticulosis, the following notation would be a more appropriate documentation:
Patient here to discuss results from colonoscopy. Patient reports no adverse symptoms from colonoscopy performed on May 14, 2001; no bleeding, fevers or abdom-inal pain reported postprocedure. Vital signs stable as noted.
Fifteen (15) minutes face-to-face counseling about diverticulosis, reviewed other potential diagnoses and therapeutic options. Patient's husband was also present to review and discuss therapeutic options. All questions from patient answered. Don't see the need for routine follow-up studies unless there is a change in symptoms. Patient can return to primary care physician for monitoring and longitudinal follow-up and management of care.
Plan: no seeds or nuts in diet. Use psyllium husks taken with water as a dietary supplement on daily basis, take with less water if causes diarrhea. Given informational brochures about diverticular disease and diet. Contact office if patient develops gas, bloating, change in bowel movements, abdominal pain, fevers or signs of gastrointestinal bleeding.
Visit lasted 15 minutes. 10 minutes spent in counseling.
Brink agrees that it doesn't take a lot of time to do thorough documentation. "You don't need to list all the questions that the patient asked just that you answered the questions to show a verbal exchange," she says.
When time is used as the key component, Brink emphasizes, the total time spent face-to-face with the patient should be considered and not just the amount of time spent counseling.
Not all follow-up visits -- particularly those with more complicated medical decision-making -- will be determined by the amount of time spent with the patient. For instance, instead of diverticulosis, the patient has a broad-based sessile polyp in the colon, part of which is shaved off during the colonoscopy and sent for a biopsy. The pathology report is indeterminate.
In this case, the gastroenterologist has many more factors to consider as part of the medical decision-making, says Brill. Is the polyp cancerous, precancerous or benign? Should you do another colonoscopy? Do you send the patient for further studies such as an endoscopic ultrasound or a CAT scan or do you need to consider a surgical referral? "The level of medical decision-making is at least moderate," he says.
Depending on the level of history or exam that occurs during the visit, the gastroenterologist could be billing a level-three (99213) or level-four (99214) office visit. However, the gastroenterologist will probably spend nearly the same amount of time with the patient, 15 or 20 minutes, as he or she did with the diverticulosis patient, says Brill.
Because the suggested time limit for a level-three visit is 15 minutes and a level-four visit is 25 minutes, time spent coordinating care and counseling will not be a factor in determining the level of this encounter.
Both Brink and Brill agree that auditors frequently downcode the level of an E/M visit when it is based solely on time. However, that is usually because the necessary documentation to justify the time spent is not in the chart. "If you go by counseling to determine the level of visit," Brink says, "you have to document it clearly."
