Using the CPT ® codebook to look up Strabismus in the index. Strabismus surgery would be performed to correct which of the following eye disorders? |
Balancing the strength of extraocular muscles Response Feedback: RATIONALE: Strabismus in the CPT® index takes you to code range 67311-67345. In the text, find the subheading entitled Extraocular Muscles. All of these codes involve the muscles moving the eyeball, and most of these codes address adjusting one or more ocular muscles to correct an imbalance in the muscles causing the eye to be pulled too much in one direction, causing disorders like crossed or wandering eyes. |

Which of the following statements is true regarding the vitreous humor? |
It holds the retina firmly against the blood-rich choroid. Response Feedback: RATIONALE: Vitreous humor is a gel-like substance in the posterior segment. In addition to its refractive qualities, the vitreous is responsible for holding the shape of the eyeball and keeping the retina pressed against the blood-rich choroid in the posterior segment. |

A child is exhibiting leukocoria in the left eye, and an MRI of the skull is ordered to rule out retinoblastoma. What diagnosis code is reported? |
H44.532 Response Feedback: RATIONALE: Look in the ICD-10-CM Alphabetic Index for Leukocoria and you are directed to see Disorder, globe, degenerated condition, leucocoria. Disorder/globe/degenerated condition/leucocoria directs you to H44.53-. In the Tabular List, 6th character 2 is reported to indicate the left eye. Leucocoria reports a symptom rather than an actual diagnosis. In leucocoria, an abnormal white reflection from the retina is visible through the pupil upon examination of the eye. It can be indicative of retinoblastoma, a congenital retinal cancer, but until this diagnosis is confirmed, the symptom of leucocoria is the appropriate diagnosis to report. |

The patient has been compliant with his Xalatan eye drops and his intraocular pressure (IOP) is now within normal limits at 20 mm Hg. The glaucoma seems to be in good control. He will continue the current regime and return for a follow-up exam in six months. What diagnosis code is reported? |
H40.9 Response Feedback: RATIONALE: There is not a lot of information to work with and H40.9 Unspecified glaucoma is the appropriate choice. In the ICD-10-CM Alphabetic Index, look for Glaucoma and the default code is H40.9. In a medical office, you would have access to the entire patient record and to the physician to find out more about the type of glaucoma. The important thing to remember is the patient still has glaucoma, despite the normal (WNL is within normal limits) IOP (intraocular pressure). Code Z86.69 is inappropriate because it reports a history of a resolved condition. |

The patient reports she turned her head quickly while pruning a dogwood tree in her yard and a branch entered her right ear. She states that when she performs a Valsalva maneuver (exhaling with the mouth and nose firmly closed), she can hear air course through her ear. On examination, there is no foreign body present. A small perforation of the right eardrum is noted, which should heal independent of treatment. Her ear will be re-evaluated in two weeks. Select the correct diagnosis codes. |
S09.21XA, W60.XXXA, Y92.017, Y93.H2 Response Feedback: RATIONALE: This is an acute injury and in ICD-10-CM injuries have different categories for open wounds, lacerations, bites, and are specific to with or without a foreign body. In the ICD-10-CM Alphabetic Index, look for Wound/puncture wound - see Puncture. Look for Puncture/ear/drum directing you to S09.2-. In the Tabular List subcategory S09.2- requires a 5th digit for laterality and a 7th character for the type of encounter. Because S90.21 is a five-character code, the place holder X is needed to maintain the 7th character position. The complete code is S09.21XA. Codes in the H72.0- subcategory are for perforations persisting after an illness or injury is resolved. Code S00.401- is for a superficial injury, but this isn’t superficial because it is in the middle ear. Do not confuse simple with superficial. External cause codes describe the circumstance of the injury. These codes are found in External Cause Of Injuries Index. Look for Contact/with/plant thorns, spines, sharp leaves or other mechanisms W60.Category W60 requires a 7th character for type of encounter. Because this is a three-character code, the placeholder X is needed to maintain the 7th character position. The complete code is W60.XXXA.. Next, in the External Cause Of Injuries Index for look for Place of occurrence/yard, private/single family house Y92.017. In the same index look for Activity/gardening Y93.H2. Verify these codes in the Tabular List. These External cause codes help establish the cause of the injury for the payer. |

The patient underwent a plastic repair of the external auditory canal for stenosis, a late effect of a burn. After excising the subepithelial stenotic tissue and a wedge of skin from the floor of the external auditory canal, a rubber tube was placed inside the external canal. The patient will return in two weeks to monitor his progress. What CPT® code is reported for this procedure? |
69310 Response Feedback: RATIONALE: In the CPT® Index, see Meatoplasty/External Auditory Canal 69310. The external opening of the ear is referred to as the meatus. A meatoplasty enlarges the opening. Another index option is to look for Auditory Canal/External/Reconstruction/for Stenosis 69310. |

|
A patient underwent mastoidotomy for ossicular chain reconstruction with tympanic membrane repair, atticotomy, and partial ossicular replacement prosthesis. What CPT® code is reported for this procedure? |
69637 Response Feedback: RATIONALE: In the CPT® Index, look for Mastoidotomy. Code 69637 represents a mastoidotomy (including atticotomy and tympanic membrane repair) with ossicular chain reconstruction and partial ossicular replacement prosthesis. |

The patient is complaining of severe corneal pain and believes a wood chip entered his eye. He was working in his woodworking shop without goggles this morning. After placing two drops of proparacaine 0.5% in the right eye, I administered fluorescein and examined the cornea under ultraviolet light using a slit lamp. Seidel sign negative for penetrating injury. A small piece of wood was identified under a flap of lamellar cornea, and I was able to dislodge the wood and flush it from the eye. A single suture was placed to secure the flap. What CPT® code is appropriate for this procedure? |
65275 Response Feedback: RATIONALE: The presence of the foreign body has no bearing on code selection. In the CPT® Index , see Cornea/Repair/Wound/Nonperforating 65275. Note the code reads with or without removal of foreign body. The key to code choice is the site of the injury, which is the cornea and it was a nonperforating injury (lamellar means partial thickness of the cornea). The topical anesthetic is bundled into the procedure, although the physician could bill separately for any IV sedation used or if a therapeutic contact lens was applied. |

|
A patient has an oversized and embedded dacryolith in the lacrimal sac, and a dacryocystoectomy is performed. What CPT® code(s) is/are reported for this procedure? |
68520 Response Feedback: RATIONALE: In the CPT® Index, look for Dacryocystectomy referring you to 68520. The stone was embedded in the sac, which was removed. Only one code is used for removal of the stone and removal of the sac. The lacrimal gland is located near the eyebrow; the lacrimal sac is the upper dilated end of the lacrimal duct, aligned with the nostril. |
|
|
What CPT® code is used to report surgery to remove an aqueous shunt from the patient’s extraocular posterior segment of the eye? |
67120 Response Feedback: RATIONALE: An aqueous shunt is implanted material in the extraocular posterior segment of the eye. In the CPT® Index, look for Eye/Removal/Implant/Posterior Segment referring you to 67120-67121. It can also be found by looking for Removal/Implant/Eye. |
