1. Procedure and CPT® Code Selection:

The patient required surgical intervention for severe ocular trauma involving removal of a foreign body from the posterior segment of the eye, suturing of the corneal laceration, and a pars plana lensectomy.

CPT® Code 65265 is for removal of a foreign body from the posterior segment of the eye without the use of a magnet. This code is appropriate for the removal of the metallic foreign body using retinal forceps.

CPT® Code 66852 covers the pars plana lensectomy, which was performed as part of the surgical treatment.

CPT® Code 65280 is used for repairing a corneal laceration with multiple perforations, which applies to the corneal suturing.

2. Modifiers:

Modifier RT is used to indicate that the procedures were performed on the right eye.

Modifier 51 is added to indicate multiple procedures performed during the same surgical session.

3. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code S05.51XA is appropriate for penetrating wound of the right eyeball with a foreign body in the posterior segment.

ICD-10-CM Code W31.1XXA is used to indicate that the injury was caused by contact with a metalworking and woodworking machine.

4. Rationale for Excluding Other Options:

Codes 65235 and 65275 in options B, C, and D refer to foreign body removal from the anterior chamber and the anterior segment, respectively, which are not appropriate since the foreign body was located in the posterior segment.

Codes S05.31XA and W31.0XXA in options C and D represent different eye injuries and types of machines, which do not match the scenario described.

5. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, codes should be selected based on the specific location (posterior segment) and the type of foreign body removal. Each procedure, including the corneal repair, should be coded to capture the full extent of the treatment.

Therefore, the correct answer is A. 65265-RT, 66852-51-RT, 65280-51-RT, S05.51XA, W31.1XXA.
