Procedure: Caloric vestibular testing performed on both ears with three irrigations.
CPTCode:
92537: Caloric vestibular test with recording, bilateral; bithermal (i.e., one warm and one cool irrigation in each ear).
Modifier -50: Bilateral procedure.
Code Selection Justification: The procedure performed was bilateral caloric vestibular testing with bithermal irrigation, appropriately coded with 92537 and modifier -50 for bilateral procedures.

* Esotropia of the right eye: Indicates strabismus surgery is required.
* Resection of medial rectus horizontal and lateral rectus muscles: Specific muscles addressed during the surgery.
* Adjustable sutures: Used in securing the muscles, indicating specific techniques.
* Extensive scar tissue from previous surgery: Requires additional work and isolation.
CPT codes 67314 and 67334 are used to report the resection of two muscles with adjustable sutures (67314) and surgery on an extraocular muscle involving extensive scar tissue (67334).

Pregnancy guidelines require O codes first.
O98.513 = COVID-19 infection complicating pregnancy, third trimester
U07.1 = COVID-19
Z3A.32 = 32 weeks gestation
Symptoms (SOB, fever) are not coded separately when integral to COVID-19.
Correct sequencing makes A correct.

1. Procedure and CPTCode Selection:
The test performed is a therapeutic drug assay to measure the concentration of vancomycin in the patient's blood.
CPTCode 80184 is specific for a therapeutic drug assay of vancomycin, making it the correct code to report for this test.
2. Rationale for Excluding Other Options:
Code 80197 is used for therapeutic drug assays of another antibiotic, gentamicin, and does not apply to vancomycin.
Code 80202 is for measuring the levels of cyclosporine, another drug, and is not relevant to vancomycin.
Code 80299 is for an unlisted therapeutic drug assay, which is unnecessary since a specific code (80184) exists for vancomycin.
3. AAPC and CPTCoding Guidelines:
According to AAPC guidelines, specific therapeutic drug assay codes, like 80184 for vancomycin, should be used when available.
Therefore, the correct answer is C. 80184.

Procedure: Complete cardiac MRI for morphology and function without contrast, followed by contrast with four additional sequences and stress imaging.
CPTCodes:
75561: Cardiac MRI for morphology and function without contrast material.
75563: Cardiac MRI with contrast and further sequences.
ICD-10-CM Codes:
I50.1: Left ventricular failure.
I49.1: Premature ventricular contractions.
Code Selection Justification: The CPTcodes accurately capture the MRI procedures performed. The ICD-
10-CM codes represent the diagnoses of left ventricular failure and premature ventricular contractions.
