90378 = RSV monoclonal antibody, 50 mg per dose

100 mg = 2 units

96372 = Therapeutic IM injection

Vaccine admin codes (90460/90471) do not apply

99291: This code is used for the first 30-74 minutes of critical care, evaluation, and management of the critically ill or critically injured patient.

99292: This code is used for each additional 30 minutes of critical care service beyond the first 74 minutes.

The documentation indicates that the patient received a total of 45 minutes of critical care, which involves continuous IV insulin for diabetic ketoacidosis, administration of antiemetics, and admission to the ICU. The critical care time documented justifies the use of 99291 for the first 30-74 minutes and 99292 for each additional 30 minutes.

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.

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

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).

CPT® code 69644 refers to a tympanoplasty with mastoidectomy, which includes canalplasty, middle ear surgery, and tympanic membrane repair. The specific procedure described by this code is performed with an intact or reconstructed canal wall and includes ossicular chain reconstruction. The use of a semicolon in the CPT® description helps distinguish between different variations of the procedure.

AMA ' s CPT® Professional Edition, specific code descriptions and guidelines.

The procedure described involves a LeFort I reconstruction, which is a type of orthognathic surgery performed to correct deformities of the midface. In this scenario, the surgeon performed the reconstruction in two pieces, moving the upper jawbone forward and repositioning the teeth of the maxilla. According to the CPT® guidelines, CPT code 21146 describes a LeFort I (maxilla only) osteotomy, two-piece segment, including bone grafts (includes obtaining autografts). This code matches the description provided.

A “subcutaneous cardiac rhythm monitor” describes animplantable loop recorder(insertable cardiac monitor) placed under the skin for long-term rhythm surveillance. When the entire monitor system isremoved, CPT provides a specific removal code rather than using pacemaker/ICD removal codes.33286is the CPT code forremoval of an insertable cardiac monitor. The timing (14 months after implantation) supports that this is not an immediate post-op revision but a standard removal after monitoring is complete or the device is no longer needed. The distractors represent other cardiac device services:33241is removal of an implantable defibrillator pulse generator (not a loop recorder), and33272/33273relate to other cardiac device procedures rather than removal of an insertable monitor. CPC strategy: identify the device category—loop recorder/insertable cardiac monitor—and match the service—removal—to the dedicated code. This avoids incorrectly reporting pacemaker/ICD codes, which are different devices with different procedural work and coding families.

According to ICD-10-CM burn guidelines:

When burns of different degrees occur at the same site, only the highest degree is coded, not separate codes.

The other statements are true:

Necrosis is coded as a non-healed burn

Burn codes include electrical and radiation burns

The highest degree burn is sequenced first

00537 = Anesthesia for EP procedures

P1 = Normal healthy patient

The operative note describes anopen radical hysterectomyfor endometrial cancer with removal of theuterus, tubes, and ovaries(specimens listed) and extensive dissection ofuterine arteries, uterosacral and cardinal ligaments, consistent with aradicalprocedure. The approach is clearlyabdominal/open(midline vertical incision and abdominal entry), not laparoscopic, so a laparoscopic radical hysterectomy code (such as 58548) is not appropriate. In the answer set,58210represents aradical abdominal hysterectomy(with appropriate extent for malignancy management). In addition, the surgeon performedpelvic lymph node samplingbilaterally, removing lymphatic tissue along the iliac vessels to the obturator nerve region. The correct code in the choices for pelvic lymphadenectomy/sampling is38770. Pelvic washings and extensive exploration are included in the primary surgical service and do not add separate CPT codes in this scenario. Therefore, the correct coding combination is58210 and 38770.

1. Procedure and CPT® Code Selection:

The patient underwent a 7-view X-ray of the lumbosacral spine, which included bending views. A complete set of views is captured.

CPT® Code 72114 is appropriate for a complete lumbosacral spine X-ray with a minimum of six views. This code includes comprehensive imaging, such as bending and other specialized views, which were taken in this scenario.

2. Rationale for Excluding Other Options:

Code 72020 is for a single-view X-ray of the spine, which is not adequate to describe a 7-view series.

Code 72080 is for a two- or three-view X-ray of the thoracolumbar spine, which does not cover the full set of seven views described in this scenario.

Code 72084 represents a complete thoracic spine study with multiple views but does not specifically cover the lumbosacral spine, which is the focus of this X-ray examination.

3. AAPC and CPT® Coding Guidelines:

According to AAPC and CPT® guidelines, 72114 is the correct choice for a complete lumbosacral spine study involving multiple views, including specialized views like bending.

Therefore, the correct answer is C. 72114.

Procedure: Visual field examination of both eyes using Goldmann perimeter testing with four isopters.

CPT® Code:

92082: This code is for visual field examination with intermediate examination.

ICD-10-CM Code:

G43.009: Migraine without aura, not intractable, without status migrainosus.

Code Selection Justification: The visual field exam method and complexity align with 92082. The patient ' s diagnosis of non-intractable migraine without aura is coded as G43.009.

AMA CPT® Professional Edition (current year)

ICD-10-CM (current year)

Procedure Coding (CPT®):

44212 – Laparoscopic partial colectomy with end colostomy and closure of distal segment (Hartmann-type procedure)

Correct because:

Sigmoid/descending colon resection

Proximal colostomy created

Distal rectal stump closed

44213 – Laparoscopic mobilization of splenic flexure

Separately reportable because:

Mobilization was necessary to exteriorize colon for colostomy

Not bundled into 44212

Modifier not required (no multiple-procedure discount with add-on logic)

Diagnosis Coding (ICD-10-CM):

K57.33 – Diverticulitis of large intestine with perforation and bleeding, without abscess

Documentation supports:

Diverticulitis

Active bleeding

No abscess reported

Why Other Options Are Incorrect:

A / B – 44206 = colectomy with anastomosis (not performed)

A / B – K57.41 includes abscess (not documented)

C – Missing splenic flexure add-on explanation

CPT® & ICD-10-CM Guideline Alignment:

Hartmann procedure ≠ anastomosis

Bleeding elevates diagnosis specificity

Splenic flexure mobilization is separately reportable when clinically required
