Detailed Answers (Verified Answers)
Question: Define diagnostic reasoning
Ans: -A type of critical thinking
-Includes systematic way of thinking that evaluates each new piece of data to
support some hypothesis and reduce others
-Evaluates if all the avenues have been explored and that the conclusion is
based on evidence
-To solve problems, promote health, screen for dz/illness: all require
sensitivity to complex stories, contextual factors, sense of
probability/uncertainty

Question: Describe the differences between medical billing and

Represented by 5 digit code
Every CPT must have dx that corresponds/explains why procedure was done
ICD-10: 10th version
Shorthand for pt's dx used to provide payer info on necessity of
visit/procedure
Question: Discuss how specificity, sensitivity, predictive value
contribute to usefulness of diagnostic data

, 4
Ans: Specificity: greater when it has few false positives
The number of true negatives divided by the number of all tested individuals
who do not have the dz
Sensitivity: greater when it has few false negatives
The number of true positives divided by the number of tested individuals that
do have the dz
Predictive value: in part dependent on prevalence of condition
Positive predictive value: the number of true positives divided by all those
that are positive
Negative predictive value: the number of true negatives divided by all those
that are negative
False positive: when a pt does NOT have dz, but has positive reading
False negative: when a pt that DOES have dz, but has negative reading
Question: Discuss the elements that need to be considered when
developing a plan
