An esophagogastroduodenoscopy (EGD) was performed with the removal of a polyp using hot biopsy forceps.

Procedure Description:

An EGD was performed.

A polyp was found in the duodenum and removed with hot biopsy forceps.

CPT® Coding:

43250: Esophagogastroduodenoscopy, flexible, transoral; with removal of tumor(s), polyp(s), or other lesion(s) by hot biopsy forceps.

CPT® code 46255 describes the excision of both internal and external hemorrhoids, which matches the procedure described. The ICD-10-CM codes K64.0 (First degree hemorrhoids) and K64.4 (Residual hemorrhoids) describe the conditions treated.

This scenario describes an anterior discectomy and arthroplasty at two levels (L3-L4 and L5-S1) using artificial discs. CPT® code 22857 describes total disc arthroplasty (artificial disc), anterior approach, including discectomy to prepare interspace (other than for decompression), single interspace, lumbar. Since the procedure was performed at two levels, the code should be reported twice.

For this scenario, two surgeons are working together, each as a primary surgeon. Therefore, the correct coding requires the use of the modifier -62, which indicates co-surgeons.

The transthoracic approach to excise the damaged portion of the vertebral body is coded with 63087.

The insertion of the bone graft and metal plate is coded with 63088.

Both codes are appended with modifier -62 to indicate that two surgeons worked together as primary surgeons on this case.

According to ICD-10-CM coding guidelines for substance use, abuse, and dependence, when multiple levels (use, abuse, and dependence) of the same substance are documented, only the highest level of severity is coded. The hierarchy is as follows: dependence > abuse > use.

D. If both use and dependence are documented, assign only the code for dependence is correct, as dependence represents the highest severity level and supersedes both use and abuse.

A. is incorrect because if both use and abuse are documented without dependence, only abuse would be coded as it is of a higher severity than use.

B. is incorrect because all three codes (use, abuse, dependence) should not be reported together; only the highest level should be coded.

C. is incorrect because if both abuse and dependence are documented, only dependence (the higher severity level) should be coded, not abuse.

Therefore, the correct answer is D. If both use and dependence are documented, assign only the code for dependence.

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.

The injection into the trochanteric bursa under ultrasonic guidance is coded with CPT® 20611, which describes an injection of a major joint or bursa with ultrasound guidance. The modifier -LT indicates the procedure was performed on the left side.

CPT code 11102 is for punch biopsy of skin, including simple closure. CPT code 12001-51 is for simple repair of superficial wounds, with modifier 51 indicating multiple procedures. ICD-10-CM code D49.2 is used for a neoplasm of unspecified behavior of the bone, soft tissue, and skin. This coding accurately reflects the punch biopsy and simple repair performed on the lesion.References: AMA's CPT® Professional Edition (current year), ICD-10-CM (current year)

The patient with malignant lymphoma is administered Rituximab (800 mg) and Benadryl (100 mg) intravenously.

Procedure Description:

Administration of Rituximab (800 mg) intravenously.

Administration of Benadryl (100 mg) intravenously.

HCPCS Level II Coding:

J9312: Injection, Rituximab, 10 mg.

For 800 mg, report 80 units of J9312.

J1200: Injection, Diphenhydramine HCl, up to 50 mg.

For 100 mg, report 2 units of J1200.

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.References: ICD-10-CM, medical dictionaries, and oncology textbooks
