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

• 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
  v67 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
              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
             In general…
• For residents…Give name of staff you
  discussed the case with.
• Vital signs must be stated to have been
• EKG must be reviewed in your note to
  obtain credit for having done it (CPT
• 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.
