CPC Exam Dumps - AAPC Certified Professional Coder Questions and Answers

For diabetes coding, you must first select the diabetes category that matches the type:Type 1 diabetesisE10.-(not E11, which is Type 2). “Diabetic chronic kidney disease” maps toE10.22(Type 1 diabetes mellitus with diabetic chronic kidney disease). ICD-10-CM guidelines then require anadditional codeto identify thestage of CKDfromN18.-. Because the question does not specify the CKD stage, you assignN18.9(chronic kidney disease, unspecified). That makesE10.22, N18.9correct (Option B). Option D would only be correct if the stage were specifically documented asCKD stage 1 (N18.1). Option C (E10.21) is diabetes with diabetic nephropathy, which is not the same as “diabetic CKD” in this question. CPC exam tip:E10.22 always needs an N18.- stage codewhen stage is known; if not known, useN18.9.

Warthin ' s tumor, also known as papillary cystadenoma lymphomatosum, is a benign tumor of the salivary glands, most commonly affecting the parotid gland. It typically presents as a painless, slow-growing mass near the angle of the jaw.

Procedure: Impedance testing via tympanometry is performed to assess hearing loss in the left ear.

CPT® Code:

92567: This code is for tympanometry (impedance testing) without reflex threshold measurements.

Code Selection Justification: The procedure involved tympanometry without reflex threshold, which is specifically coded as 92567.

AMA CPT® Professional Edition (current year)

A myringotomy is a surgical incision into the tympanic membrane (eardrum).

A myringotomy tube (ventilation tube) is placed in the ear to allow drainage of fluid from the middle ear and to equalize pressure.

Therefore, the correct answer is A. Ear.

Autopsy CPT coding is based on theextent of the examination(gross only vs gross and microscopic) and whether special anatomic components (such asbrain and spinal cord) are included. The question states the pathologist performedboth gross and microscopicexamination and explicitly included thebrain and spinal cord, which indicates acomprehensive autopsyservice rather than a limited or gross-only autopsy. CPT88028represents a complete autopsy with gross and microscopic examination that includes examination of the central nervous system structures (brain and spinal cord) as part of the comprehensive scope. The other codes listed represent different autopsy levels or components that do not match the “gross and microscopic” plus CNS inclusion described. CPC exam approach: anchor first ongross + microscopic(not gross-only), then look for wording that indicates acomplete autopsy. When the stem highlights “brain and spinal cord,” it is signaling the higher-complexity comprehensive autopsy code selection. Therefore,88028is the correct CPT code.

Repair of wound dehiscence → CPT 13160 (complex repair, secondary closure)

Occurs during global period and is unplanned → Modifier -78

Modifier -58 is for staged or planned procedures.

ICD-10-CM guidelines state that healing pressure ulcers are coded as the stage documented.

L89.624 = Pressure ulcer of left heel, stage 4

Stage 4 ulcers involve full-thickness tissue loss and are commonly referenced in exam scenarios involving treatment of healing ulcers

Unspecified stage or laterality codes are not appropriate when documentation supports specificity.

K0001 = Standard wheelchair

Other K000 codes represent specialized wheelchairs

In the CPT® book, codes that contain a semicolon (;) indicate that the portion of the description before the semicolon applies to all codes in that series, and the text after the semicolon completes the individual code description.

For the small intestinal endoscopy (enteroscopy) codes:

The parent code describes: “Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum;”

CPT® 44361 specifically adds: “with biopsy, single or multiple.”

Therefore, the full description of CPT® 44361 is:

Small intestinal endoscopy, enteroscopy beyond second portion of duodenum, not including ileum; with biopsy, single or multiple.

1. Procedure and CPT® Code Selection:

The scenario describes a labial gland biopsy of the salivary gland, performed in the office with a local anesthetic. The provider made an incision in the lower labial mucosa and took tissue samples from the salivary gland for biopsy.

Code 42400 is the correct CPT® code for a biopsy of a salivary gland. This code is specific to a biopsy without a more extensive excision or major surgery, aligning perfectly with the scenario of sampling salivary gland tissue.

2. Ruling Out Other Options:

Code 42408 is for the excision of a deep lobe of a parotid gland, which is a more extensive procedure than a simple biopsy and does not apply to this case.

Code 42405 is for the removal of an entire submandibular gland, which is a full excision and not applicable here.

Code 42450 is used for the removal of a sublingual gland, not for a biopsy of the labial salivary gland.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines direct coders to use 42400 for minor biopsies of salivary gland tissue, particularly when only tissue samples are taken for diagnostic purposes, as described in this case.

Based on CPT® coding guidelines, the correct answer is C. 42400.
