The Schede thoracoplasty for empyema is accurately described by CPT code 32905, which covers the radical procedure involving the resection of multiple ribs and often the obliteration of the pleural cavity to treat chronic empyema.

CPT code 99450 is used for the examination of a patient for the purpose of establishing medical baseline information or for insurance purposes. Since Eric ' s primary care provider completed the required physical exam documentation for his life insurance policy, this is appropriately reported with code 99450. References: CPT® Professional Edition (current year), AMA.

The CPT code 10005 is for fine needle aspiration biopsy, including ultrasound guidance, for the first lesion. CPT code 10006 is for each additional lesion with ultrasound guidance. Since the provider aspirated tissue from three nodules, the coding should be 10005 for the first nodule and 10006 x 2 for the additional two nodules.

Laminectomy and Facetectomy (63047 and 63048): The laminectomies at L4 and L5 with facetectomies fall under CPT codes 63047 (for the initial segment) and 63048 (for each additional segment).

Posterior Arthrodesis (22612 and 22614 x 3): The posterior arthrodesis from L1-L5 is coded with 22612 for the primary segment (L4-L5) and 22614 for each additional segment (L1-L4).

Placement of Pedicle Screws (22842): The placement of pedicle screws at L2, L3, and L4 is captured under CPT code 22842 for segmental instrumentation.

This is aninitial hospital/observation evaluation(first visit during the stay), so the correct code family is theinitial observation/inpatient E/Mlevel. The stem providestotal time = 85 minutesand also statesmoderate MDM. Under current E/M rules, you can select the code based oneither MDM or total time(when time is used, it includes the physician’s qualifying time on that date). The time of85 minutesfits the time range for99223(the highest initial hospital/observation level by time) even if MDM is described as moderate. The prolonged service add-on99418requires meeting the threshold beyond the primary code’s time before it can be added; with 85 minutes, you do not reach the additional increment needed to report 99418. Therefore, you report99223 only. CPC exam tip: when time is explicitly provided and is high, it often drives the level; do not add prolonged time unless the documented time clearly exceeds the primary code’s requirement by the necessary increment.

Procedure: Complete cardiac MRI for morphology and function without contrast, followed by contrast with four additional sequences and stress imaging.

CPT® Codes:

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 CPT® codes accurately capture the MRI procedures performed. The ICD-10-CM codes represent the diagnoses of left ventricular failure and premature ventricular contractions.

Procedure Coding (CPT®):

31287 – Nasal/sinus endoscopy, surgical; with sphenoidotomy

Correct because the surgeon performed a surgical endoscopic sphenoidotomy to evaluate and treat sphenoid sinus injury.

No CSF leak repair was performed, so codes 31290–31291 are not appropriate.

31231-59 – Nasal endoscopy, diagnostic

Diagnostic endoscopy is separately reportable because:

It was performed to evaluate traumatic injury

It is not bundled into the surgical service when it provides distinct diagnostic information

Modifier -59 indicates a separate and distinct service per NCCI edits.

Diagnosis Coding (ICD-10-CM):

S02.109A – Unspecified fracture of base of skull, initial encounter for closed fracture

The anterior cranial fossa fracture with sphenoid sinus involvement qualifies as a skull base fracture

No CSF leak is documented

Correct 7th character “A” for initial encounter

Why Other Options Are Incorrect:

A – Incorrect format and duplicated CPT logic

B – 31267 = maxillary sinus, wrong sinus

D – 31291 includes CSF leak repair, which was not performed

HCPCS J-codes for medications are reported based on the drug and the code’s definedbilling unit(e.g., mg per unit).Ondansetronis reported withJ2405, which is typically defined per1 mg(so 2 mg is reported as2 units→ J2405 × 2).Ketorolac tromethamineis reported withJ1885, commonly defined per15 mg(so a 15 mg dose is1 unit→ J1885). Option A matches this unit logic:J2405 × 2for 2 mg ondansetron, plusJ1885for 15 mg ketorolac. Option B incorrectly multiplies ketorolac by 15 units, which would overstate the dose because the code unit is not 1 mg in this context. Option C underreports ondansetron units if the unit is 1 mg. Option D uses an incorrect J-code for ketorolac. CPC exam tip: always read theJ-code unit definitionand convert the administered dose into billable units accurately.

Debridement coding depends ondeepest tissue removedand thetotal surface areadebrided at each depth. Debridement “tomuscle and/or fascia” is coded with11043for thefirst 20 sq cm (or part thereof)at that depth. The lower-back wound involvesfascia, so report11043(no add-on 11046 is needed because the described size is below an additional 20 sq cm threshold). The shoulder (8) and lower-leg (16) wounds involvesubcutaneous tissue, which is coded with11042for thefirst 20 sq cm (or part thereof)at the subcutaneous depth. Their combined area is24 sq cm, so you report11042plus add-on11045for theadditional 4 sq cmbeyond the first 20. Because two different depth families are billed (fascia vs subcutaneous), adistinct procedural servicemodifier (here-59on 11042) supports reporting both depths when documentation shows separate wounds/levels treated. This matches optionD.

80143 = Acetaminophen level

80324/80329 = Drug classes, not specific analytes

80299 = Unlisted therapeutic drug assay
