The patient has undergone a left total knee arthroplasty and subsequently received a femoral nerve block for postoperative pain management. CPT code 01402 is used for anesthesia for total knee arthroplasty. Code
64447-59-LT is for a femoral nerve block (single injection) for postoperative pain management, with modifier
59 indicating a distinct procedural service and LT indicating the left side. Therefore, the appropriate codes are
01402 and 64447-59-LT.

Procedure Code:
90945 - Continuous renal replacement therapy (CRRT), daily
Includes repeated low-level E/M monitoring
Correct for CVVH
Diagnosis Codes:
I10 - Essential hypertension
N18.9 - Chronic kidney disease, unspecified
Why others are incorrect:
90935 / 90937 - Intermittent hemodialysis
90947 - Pediatric CRRT
ICD-9 codes (112.9, 110) are invalid

This question is testing recognition of amaxillofacial prosthetic servicerather than an ophthalmology procedure code. The vignette describesfabrication of a prosthesis using silicone materialswithmodificationsintended to restorecosmetic appearanceafter loss/damage of an eye. Among the provided options,21086is the CPT code that corresponds to fabrication of afacial prosthesis(commonly silicone-based) with the intent of external restoration. The other codes in this small cluster represent different facial/craniofacial repair or prosthetic services and do not match silicone prosthesis fabrication described in the scenario. CPC exam technique: focus on the key nouns-"fabricates a prosthesis," "silicon materials,"
"cosmetic appearance restoration"-which point away from repair codes and towardprosthetic fabrication.
Also note the question is not about insertion of an ocular implant during enucleation/evisceration, but about crafting an external prosthetic device. Therefore, the correct selection is21086.

The scenario describes an emergency basic life support (BLS) ambulance service. The appropriate HCPCS Level II code for BLS emergency transport is A0429.
Modifier QN indicates that the service was provided by an ambulance supplier, and SH indicates the services were provided in an emergency situation.

1. Procedure and CPTCode Selection:
The emergency department physician placed an indwelling catheter into the lumbar region for continuous infusion for pain management with fluoroscopic guidance.
CPTCode 62327 is appropriate for injection or catheter placement for continuous infusion of anesthetic or analgesic in the lumbar or sacral region using imaging guidance.
CPTCode 77003 represents the fluoroscopic guidance used during the catheter placement, which is separately reportable in this case.
2. Rationale for Excluding Other Options:
Code 62326 (in options B and D) is for the injection or catheter placement without imaging guidance. Since fluoroscopic guidance was specifically mentioned, 62327 is the appropriate choice.
Code 77003 must be reported separately when fluoroscopy is used in conjunction with 62327 for pain management catheter placement.
3. AAPC and CPTCoding Guidelines:
According to AAPC guidelines, the combination of 62327 and 77003 is correct when catheter placement for continuous infusion is performed with fluoroscopic guidance.
Therefore, the correct answer is C. 62327, 77003.
