Question: A patient came in for a physical exam. While there, one of our physicians also diagnosed the patient with a sore throat. What is the best way to code for this scenario?

Answer: To arrive at a definitive answer, you’ll need to answer several questions about the patient.

Ask these Px status questions: You can code the exam in several different ways, assuming it is preventive in nature. If the patient is a new patient, you would use 99381-99387 (Initial comprehensive preventive medicine evaluation and management of an individual …); if the patient is established, you would use 99391-99397 (Periodic comprehensive preventive medicine reevaluation and management of an individual …). The exact code would then be determined by the patient’s age per the codes’ descriptors.

Add problem-focused E/M: Mary I. Falbo, MBA, CPC CEO of Millennium Healthcare Consulting, Inc., in Lansdale, Pennsylvania, notes that “if the patient complaint requires additional workup, beyond that usually associated with the preventive service, you may choose to report a problem-focused E/M service in addition to the preventive service.”

So, per the CPT^® codebook, you should report the appropriate Office/Outpatient code 99201-99215 and provide documentation of a separate HPI (history of present illness) to support both services.

Accurately document the patient’s condition: A recent onset of the condition would be coded in the J02 category (Acute pharyngitis …). If the cause of the sore throat is not specified, you would code J02.9 (Acute pharyngitis, unspecified), but if the physician does identify the cause of the sore throat, you can go further and code J02.0 (Streptococcal pharyngitis) or J02.8 (Acute pharyngitis due to other specified organisms).

Remember: If J02.8 is the correct code to use for the patient’s diagnosis, you won’t be able to use any of the other codes outside of the J02 category, as J02.8 excludes any other code being used.

J02.8 can then be accompanied by additional codes in the B95-B97 categories to pinpoint the exact bacterial or viral agent. But if the sore throat is symptomatic of another illness, it can be coded as acute pharyngitis due to gonococcus (A54.5), acute pharyngitis due to herpes [simplex] virus (B00.2), acute pharyngitis due to infectious mononucleosis (B27.-) or enteroviral vesicular pharyngitis (B08.5). And if this is not the first time the patient has experienced the condition, then J31.2 (Chronic pharyngitis) may be the most accurate way to code it.

Modifier 25 to the rescue: The key to coding the whole scenario, however, lies in appending modifier 25 (Significant, Separately Identifiable Evaluation andManagement Service by the Same Physician or Other Qualified Health Care Professional on the SameDay of the Procedure or Other Service) to the problem-oriented E/M service (99201-99215) in this scenario. This acknowledges that your physician provided an additional, separate service on the same dayas the physical.
