AAPC CPC Practice Test Questions Answers

ICD-10-CM has a clear hierarchy when the same substance is documented with multiple levels of severity.Dependencerepresents a higher severity classification thanabuse, andabuseis higher thanuse. When two or more of these are documented for the same substance, you generally assignonly one code, selecting thehighest level of severitysupported: dependence over abuse, and abuse over use. Therefore, if bothuse and dependenceare documented, you assigndependence only(Option D). Option A is incorrect because you do not code both use and abuse for the same substance; you choose the higher severity (abuse). Option B is incorrect because if abuse and dependence are both documented, you would codedependence, not abuse. Option C is incorrect because ICD-10-CM does not support reporting all three separately for the same substance; doing so would be duplicative and noncompliant. CPC exam tip: remember the mnemonicD-A-U→Dependence > Abuse > Use(pick the highest).

26910 = Excision of supernumerary digit with bone/joint involvement

11200 = Removal of skin tag / soft tissue lesion

Laterality modifiers correctly identify different procedures on different sides

Penile prosthesis coding is determined by thetype of deviceand whether the procedure is asimple insertion, areplacement, or a more complex scenario. Anon-inflatable(malleable or semi-rigid) penile prosthesis is specifically reported withCPT 54416. Inflatable devices are coded differently (commonly with a different code family), and replacement/revision services may also have distinct codes depending on what is removed and replaced. In this question, the vignette is straightforward: erectile dysfunction treated with insertion of anon-inflatable prosthesis—no mention of prior implant, revision, or removal—so the correct code is the primary insertion code for that device type. The distractors include other penile procedures and prosthesis-related codes that do not match “non-inflatable insertion.” CPC exam tip: lock onto “non-inflatable” vs “inflatable,” and then confirm the action isinsertionrather than revision or replacement. That leads to54416.

The patient was critically ill withhemodynamic instability, respiratory failure progression, and cardiac arrest, requiring intensive interventions (multiple IVs, large bolus,vasopressor infusion, resuscitation with CPR/defibrillation/medications, ABG management). The provider documents77 minutes of continuous critical care time. Critical care is reported with99291for thefirst 30–74 minuteson a date of service, and99292foreach additional 30 minutesbeyond that threshold. Because77 minutesexceeds 74 minutes, you report99291 + 99292(one unit of 99292 covers the additional time beyond the initial critical care window). You donotadditionally report an ED E/M code (e.g., 99285) on the same date for the same provider when critical care encompasses the ED evaluation and management during that time period; the critical care service is the appropriate E/M reporting. The scenario supports that critical care criteria are met: high probability of life-threatening deterioration and active physician management. Therefore, the correct E/M coding is99291, 99292.
