CPC Exam Dumps - Certified Professional Coder (CPC) Exam

99464 = Attendance at delivery with initial stabilization

99465 is used when resuscitation is required

99460 is for normal newborn care after birth

The operative approach is explicitlyopen surgery, so the correct CPT procedure code is44950(appendectomy; open). Code44970is thelaparoscopicappendectomy code and is not supported because the scenario states “open surgery.” For diagnosis, the physician’s final diagnosis ischronic appendicitis, which is reported withK36(other appendicitis) in the context of this question’s choices;K35.80represents acute appendicitis (unspecified acute) and does not match “chronic.” You also do not report symptom codes (nausea/vomiting/abdominal pain) once a definitive diagnosis is established and documented as the reason for the surgery, unless a guideline or scenario specifically requires them as additional reporting (this question does not). Therefore, the correct pairing is44950withK36only. CPC exam tip: always matchapproach(open vs laparoscopic) and code thefinal confirmed diagnosisrather than presenting symptoms when the definitive diagnosis is known.

A “recent football injury” indicates anacute traumaticinjury rather than a chronic/old derangement. Acute meniscus tears are coded from theS83.2-category (tear of meniscus, current injury), not theM23.-category (derangement of meniscus due to old tear or injury). The question specifiesmedial meniscus,left knee, and implies aninitial encounterfor the acute injury, so the correct code must include laterality and the 7th characterAfor initial encounter.S83.232Acorresponds to acurrent tear of the medial meniscus, left knee, initial encounter.S83.242Ais a different meniscus specification (not medial).M23.202/M23.204are derangement codes typically used forold tearsor chronic conditions, not an acute recent sports injury. CPC exam tip: “recent injury” →S-codes, “old tear/derangement” →M23. Mnemonic:S = Sudden (acute),M = Mature (old/chronic).

Observation E/M coding is chosen by thetype of serviceprovided on each calendar date. Day 1 includes initiation of observation with significant work (IV insulin drip, multiple labs, discussion with endocrinologist), supporting an observation initial care code. In this option set,99235represents an observation “admit and discharge on same date” style service; however, the patient stays multiple days. The question’s answer choices are structured around using99235as the initial observation care code offered, then a subsequent observation code for day 2, and a discharge code for day 3. Day 2 includes ongoing management with documented time of 25 minutes, supporting asubsequent observation carecode such as99231(as provided). Day 3 isobservation discharge, which is99238(30 minutes or less) given the documented 15 minutes. While the most current observation framework in CPT has evolved, the CPC-style expected pattern in these choices is99235 (initial), 99231 (subsequent), 99238 (discharge). Therefore, optionBmatches the intended coding sequence across the observation stay dates.

1. Procedure and CPT® Code Selection:

The patient underwent venous thrombosis imaging of each leg to assess for deep venous thrombosis (DVT).

CPT® Code 78457 is used for a venous thrombosis imaging study. This code is appropriate for imaging to detect DVT.

Modifier 50 is applied to indicate a bilateral procedure, as imaging was performed on both legs.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code I82.403 is used for acute embolism and thrombosis of unspecified deep veins of bilateral lower extremities. This code accurately describes the finding of DVT in both legs.

Other ICD-10-CM options, such as I82.401 and I82.402, specify unilateral lower extremity involvement, which does not accurately reflect the bilateral findings in this case.

3. Rationale for Excluding Other Options:

Code 78458 (in options A and D) is for a more comprehensive study, often cardiac or whole-body blood pool imaging, and is not specific to leg venous thrombosis.

Option C, which lists 78457 with individual RT and LT modifiers, is incorrect as Modifier 50 is appropriate for bilateral imaging on both legs.

4. AAPC and CPT® Coding Guidelines:

According to AAPC and CPT® guidelines, 78457 with Modifier 50 should be used for bilateral venous imaging studies, and I82.403 correctly captures bilateral DVT.

Thus, the correct answer is B. 78457-50, I82.403.

94060 = Spirometry pre- and post-bronchodilator

94010 = Baseline spirometry

J45.21 = Mild intermittent asthma with exacerbation

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.
