Gastroenterology Coding Alert

Warning: It will be futile to memorize every code set.

If you're educating yourself about ICD-10 implementation, remember one important thing: don't spend your time trying to memorize code sets.

Rhonda Buckholtz, CPC, CPMA, CPC-I, CENTC, CGSC, COBGC, CPEDC shared that advice with attendees at the AAPC's regional conference in Nashville Sept. 7-9. Buckholtz is vice president of ICD-10 education and training at AAPC and led a general session at the conference entitled "ICD-10: What You Need to Know."

"It's too soon to learn code sets, plus there's not much sense in learning them right now because final codes won't go into play until later," Buckholtz said. "It's not a bad idea to start looking at how some of your common diagnoses will change, but you really don't need to start memorizing things."

CMS representative urged the same thing during their recent call, "ICD-10 Implementation Strategies for Physicians."

"Most practitioners probably don't know many ICD-9 codes by heart, so they won't be expected to memorize ICD-10 codes either," said Daniel Duvall, MD, medical officer with CMS's Hospital and Ambulatory Policy Group, during the call.

If you follow these simple guidelines, you can prepare better.

Guideline 1: Focus on Foundations

Duvall recommended that gastroenterologists prepare for ICD-10 by looking at the ICD-9 codes they use most frequently in their offices and creating new job aids or superbills for those diagnoses. "Pick the top 30 diagnoses you see and concentrate on knowing how to code those appropriately," he said.

Example: Common diagnoses for gastroenterologists might include diarrhea (787.91 in ICD-9; R19.7 in ICD-10), toxic gastroenteritis and colitis (558.2 in ICD-9; K52.1 in ICD-10), or acute gastric ulcer with obstruction (531.01 in ICD-9; K25.0 in ICD-10).

"Every form will need updating," Buckholtz said. "If you really want to see the impact of ICD-10, take one of your most frequent diagnosis codes and follow it through your entire practice/system. See where it comes into play to help check everything you'll need to update."

Guideline 2: Brush Up On A&P Knowledge

Buckholtz said a coder's top focus should be on anatomy and physiology. "Coders will need a good understanding of so many A&P nuances with ICD-10," she said.

"Work on skill sets to get to that level of specificity so you can read your physician's documentation and pull the details you need instead of stopping the physician to ask him all the time."

Many ICD-10 codes will be more detailed than their ICD-9 counterparts, which is why adequate A&P knowledge will help coders. For example, Buckholtz said coders will need a good understanding of bones and different types of fractures with ICD-10.

New diabetes codes will explain underlying manifestations but will no longer include controlled/uncontrolled options. Neoplasm choices will expand by site (including 54 codes for male/female malignant neoplasm of breast, for example).

A&P knowledge, however, won't compensate for poor documentation. "Physicians should take the opportunity to improve their documentation skills," Duvall said. "As there are more opportunities for coders to pick from a list, they're going to be coming back to physicians early on to say 'Wait, I need more definition to help me pick A or B.'''

"Coders need to realize that physicians don't document for coding," Buckholtz said. "They document for health care. Things that weren't on their radar as important before will need to be important now. It's a great time for coders to step out of their comfort zones and learn new things, even if they're not responsible for training or implementation."
