Coding Strategy

These edits took effect April 1, so start observing them yesterday.

The latest version of the Correct Coding Initiative (CCI) has an edit that family practice coders should note – especially if the practice treats newborn patients.

Get to know the new CCI 16.1 edit and get ready to observe it with this expert breakdown. Check Column 1 on These Hospital E/Ms According to CCI 16.1, these codes are in column 1 of the mutually exclusive edits:

• 99231 (Subsequent hospital care, per day, for the evaluation and management of a patient, which requires at least 2 of these 3 key components: a problem focused interval history; a problem focused examination; medical decision making that is straightforward or of low complexity …)
• 99232 (… an expanded problem focused interval history; an expanded problem focused examination; medical decision making of moderate complexity …)
• 99233 (… a detailed interval history; a detailed examination; medical decision making of high complexity …).

Column 2 of these edits includes these codes:

• 99460 (Initial hospital or birthing center care, per day,for evaluation and management of normal newborn infant)
• 99461 (Initial care, per day, for evaluation and management of normal newborn infant seen in other than hospital or birthing center)
• 99462 (Subsequent hospital care, per day. for evaluation and management of normal newborn).

Translation: An FP may not report both normal newborn care and subsequent hospital care for a newborn on the same date of service. If the FP performs normal newborn services (99460-99462) on the same date that the newborn later becomes ill and receives subsequent hospital care (99231-99233), you should only report a code from the 99231-99233 code set, explains Kent Moore, manager of health care financing and delivery systems for the American Academy of Family Physicians (AAFP) in Leawood, Kan.

The services are mutually exclusive because the newborn care codes (99460-99463) are for “normal” newborns (i.e., newborns without medical problems); whereas the subsequent hospital care codes (99231-99233) are for problem-oriented services, Moore says.

Since both sets of services are designated as “per day,”coders must choose between them for a given patient on a given date. “Consistent with the mutually exclusive nature of these services, CCI does not permit a modifier to override the edits,” Moore continues.

Bottom line: Never report 99460-99262 and 99231-99233 for the same patient on the same date of service.

Even though Medicare no longer accepts consult codes, you can still apply modifier 57.

Question: In our ob-gyn office, we used to apply modifier 57 to inpatient consult codes. Now that Medicare doesn’t accept consult codes, how should we use this modifier?

Kentucky Subscriber

Answer: The short answer is that you should appendmodifier 57 (Decision for surgery) to the non-consult inpatient E/M code that the documentation supports.

Suppose the ob-gyn performed a 2009 level-three inpatient consult in which the ob-gyn determined the patient required an exploratory laparotomy later that sameday due to severe abdominal distention and pain as well as some uterine bleeding. Adding the modifier to the E/M code will help show payers why you’re reporting an EM in addition to the major surgery performed later that day, 49000 (Exploratory laparotomy, exploratory celiotomy with or without biopsy[s] [separate procedure]).

For 2010, the exact E&M code you choose will depend on the circumstances specific to the visit, such as whether the visit is the first or second ob-gyn visit during the admission. But as an example, suppose you’re coding the ob-gyn’s first visit to an inpatient. Your documentation may support 99221 (Initial hospital care, per day, for the evaluation and management of a patient, which requires these 3 key components: a detailed or comprehensive history; a detailed or comprehensive examination; and medical decision making that is straightforward or of low complexity …), which has requirements similar to 99253 (Inpatient consultation for a new or established patient, which requires these 3 key components: a detailed history; a detailed examination; and medical decision making of low complexity).

You should append modifier 57 to the E/M code. If, instead, the ob-gyn is the principal physician — the one overseeing the patient’s care and the one who is admitting the patient — be sure to append modifier AI (Principal physician of record), as well. This would be the case if the ob-gyn admitted the patient for observation for the abdominal pain and bleeding but later made the decision to take her to surgery that same day.

Here’s why you should append modifier 25.

Question: A 47-year-old male reports to the ED complaining of a painful, swollen, and reddening right thumb. The physician performs an expanded problem focused history and examination, which uncovers two splinters. The ED physician cannot grasp the splinters with tweezers, so she uses a scalpel to make two small incisions above the splinters. The physician then uses tweezers to remove both pieces of wood. The notes do not indicate evidence of infection at the extraction site; medical decision making is moderate. Can I code this as a foreign body removal (FBR)?

Kentucky Subscriber

Answer: Since the physician made an incision before removing the splinters, this is an FBR. On the claim, report the following:

• 10120 (Incision and removal of foreign body, subcutaneous tissues; simple) for the FBR
• 99282 (Emergency department visit for the evaluation and management of a patient, which requires these 3 key components: an expanded problem focused history; an expanded problem focused examination; and medical decision making of low complexity …) for the E/M
• modifier 25 (Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service) appended to 99282 to show that the E/M and FBR were separate services
• 915.6 (Superficial injury of finger[s]; superficial foreign body [splinter] without major open wound and without mention of infection) appended to 10120 and 99282 to represent the patient’s injury.

Explanation: The incision, or lack of it, drives code choice in this scenario. If the physician had removed the splinters without making an incision, you would have rolled the removal work into the E/M service and left 10120 off the claim.

Reading 44373’s code descriptor is key to getting your G Tube claim right.

Question: The gastroenterologist goes to the hospital to treat a patient that had recently been admitted because his gastrojejunostomy tube had migrated to his stomach. After performing a problem focused interval history and exam, the gastroenterologist decides to perform an EGD to reposition the tube. I cannot find a code for repositioning a G tube; how should I code this scenario?

Answer: Judging by your encounter description, the patient’s percutaneous jejunostomy tube (J tube) slipped and became a percutaneous gastrostomy tube (G tube). On the claim, report the following:

• 44373 (Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with conversion of percutaneousgastrostomy tube to a percutaneous jejunostomy tube) for the EGD;
• 99231 (Subsequent hospital care, per day, for the evaluation and management of a patient, which requires at least 2 of these 3 key components: a problem focused interval history; a problem focused examination; medical decision making that is straightforward or of low complexity …) for the E/M;
• modifier 25 (Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service) appended to 99231 to show that the E/M and tube fix were separate services; and
• 536.42 (Disorders of function of stomach; gastrostomy complications; mechanical complication of gastrostomy) appended to 44373 and 99231 to represent the patient’s condition.

Explanation: The descriptor for 44373 might be a bit misleading, but it mentions only “tube conversion.” The tube does not necessarily have to be new.
