The Coding Primer “How to Code” basics for primary care providers. Updated for 2009

Coding: “Can’t Live With It. Can’t Live Without It. ” • Coding is important because it builds the electronic health record. • It is the language we use to collect our fees. • It has become and will become even more the means by which we will be alotted cash and manpower.

How are we doing now? • 573 encounters audited by our coders in August 2007. • 84. 05% Diagnosis correct. • 74. 57 % Eval/management codes correct. • 67. 18 % CPT codes correct. Document what you performed. Method / Location / Quantity / Size / Layers / Time frames. • 51 % of encounters had errors found!

In general… • Code only what you know. If the diagnosis is “likely” or rule-out code for the symptoms the patient is having. E. g. CHF rule out can be coded as lower leg swelling. • Don’t code for resolved conditions. Instead use the v 67 series for follow up exams. • List complicating factors. Comorbidities, other chronic conditions the patient may have, adverse effects of medications that may be indicated. Helps to determine the complexity of the decision making process you are making.

In general… • Try to be clear about taking intermediate steps to address a patient’s condition. This can boost the complexity of the condition to the coder. Trying first physical therapy, nsaids prior to surgical consideration for example. • Use the “ 50%” button as the exception, not the rule.

In general… • Be specific about reviews of labs or xrays. Labs reviewed with patient showed elevated wbc indicating sepsis or inflammation. If a patient is following up blood pressure check tell what was wrong with the blood pressure to begin with. • Be sure to add the nurse, MA or corpstaff as an additional provider to help show clinic workload.

In general… • Medical necessity should drive ordering of labs or other diagnostic studies. Write a story that tells why these labs need to be done. The complexity of the office visit is based on the story not on the fact that so many labs were ordered. • When applicable, code “obesity” as it can help to increase the medical decision making score.

In general… • Collect credit for diagnostic decisions. If the provider went through the medical decision making process to determine a patient needed a certain test, even though the patient refused the test, the provider should receive credit for that process, provided the process is documented. E. g. colonoscopy screening / tobacco cessation counseling / obesity nutrition consults.

In general… • For residents…Give name of staff you discussed the case with. • Vital signs must be stated to have been reviewed. • EKG must be reviewed in your note to obtain credit for having done it (CPT 93000). • LOOK! At your clinic favorites for CPT codes and for Diagnoses!

Code for the -25 modifier. • When a procedure is done separate from the office visit diagnosis. When providing a specific treatment plan during a prev med visit. E. g. during a PAP smear patient brings up depression and you counsel and provide medical therapy. During an EST patient elects to start tobacco cessation and you perform counseling.
