(2022) CPT Code 66984 – Description, Guidelines, Reimbursement, Modifiers & Examples

CPT code 66984 is used to report for services when extracapsular cataract removal surgery is performed by the surgeon using the manual or mechanical technique to insert an artificial lens without endoscopic cyclophotocoagulation.

CPT Code 66984 Description

The patient with cataracts usually has poor visibility, diplopia, cloudy or blurry vision, enhanced nearsightedness, and distortion of vision.

The physician removes the nucleus of the lens capsule and the anterior shell and leaves the posterior shell of the lens capsule in place in extracapsular cataract extraction (ECCE).

The physician creates incisions in the corneal-scleral juncture (the limbus) by incorporating a lid speculum between the patient’s eyelids. To increase fluid flow in the eye, the physician may create an artificial opening in the iris.

The physician removes the lens in layers such as the anterior lens, then the inner, hard nucleus except for the clear, posterior capsule. To protect the cornea, the air bubble is administered by injection into the anterior chamber using a cutting and suction or ultrasonic device.

The physician aids in identifying the suitable place for an intraocular implant into the eye. To implant the lens in the correct or original cataract position, computer technology is used called haptics placed into the ciliary sulcus or the lens capsule.

The suture may be applied to close the incision and restore the intraocular pressure by administering the injection. The antibiotic patch or pressure may be applied to prevent infection.

CPT 66984 will be reported for service when extracapsular cataract removal surgery is performed by the surgeon with the incorporation of intraocular lens prosthesis (1 stage procedure), mechanical technique, or manual (e.g., aspiration or phacoemulsification and irrigation) without endoscopic cyclophotocoagulation

CPT Code 66984 Reimbursement

A maximum of 1 unit of CPT 66984 can be billed on the same date of service, while two units can be billed when documentation supports the medical necessity of CPT 66984.

When performed in the facility, the cost, and RUVS of CPT 66984 will be $599.62 and 17.32697, respectively. At the same time, non-facility will be $599.62 and 17.32697, respectively.

  • 22, 23, 47, 50, 51, 52, 53, 54, 55, 56, 58, 59, 63, 73, 74, 76, 77, 78, 79, 99, AI, AQ, AR, CC, CR, EY, ET, Q5, Q6, QJ, SG, XE, XU, XP, XE, XS, GA, GC, GJ, GK, GR, GU, GY, GZ, KX, LT, RT and PT.

Modifier 50 will apply to CPT 66984 extracapsular cataract-removal surgery performed bilaterally.

For instance, the patient had extracapsular cataract removal surgery on both left and right eye, and then it would be reported like 66984 -50, H26.213. 

Modifier LT or RT will be appended with CPT code 66984 if unilateral cataract surgery removal is performed. For example, the patient had extracapsular cataract-removal surgery on the right eye.

It would be reported as 66984-RT. Some insurance accepts this service as two lines, like 66984-RT and 66984, instead of billing as 1 line with modifier 50 such as 66984-50.

Check the appropriate insurance or third-party payer guidelines and bill accordingly. 

CPT 66984 has 90 days (about three months) global period, and it would start one day before the surgery, day of surgery, and post-operative.

If only one physician is provided all preoperative, surgery, and post-operative services, then there is no modifier requirement for this CPT 66984.

If an ophthalmologist shares post-operative and preoperative care with another physician, then modifier 54 (surgical only) will be applicable with CPT 66984.

Modifier 55 will be appended with a physician who provides post-operative care only, while modifier 56 will be applicable to the physician who provides preoperative care.

Modifier 23 is applicable with CPT code 66984 if general or local anesthesia is given to patients who are normally not required for the procedure.

Modifier 76 will be attached to CPT code 66984 if service is repeated by the same physician on the same date of service, while modifier 77 if the procedure has been done on the same date service by a different physician, respectively.

Modifier 78 will be appended with CPT code 66984 if the procedure is repeated with the same condition of the global period. In contrast, modifier 79 is applicable when the procedure is reported for an unrelated condition.

Modifier 59 is applicable with CPT code 66984. If any other procedure is done in combination with these services that are not normally billed together on the same date of service, then modifier 59 will be appropriate.

While modifier 51 is applicable when the other procedure is not the component of CPT 66984.

Modifier 53 will be reported with CPT code 66984 if extracapsular cataract removal surgery is terminated due to unavoidable circumstances or unstable patient conditions.

In contrast, modifier 52 is applicable when extracapsular cataract removal surgery is performed with full preparation but needs to terminate the procedure immediately and do not have the plan to redo the procedure in the future.

Then modifier 52 will be appropriate with CPT 66984.

CPT code 66984 includes Lateral canthotomy, Enzymatic zonulysis, Iridectomy/iridotomy, Anterior or posterior capsulotomy, Subtenon injection, Medications Subconjunctival injection, and viscoelastic material.

Therefore, these services will not be reported separately and routinely performed with a retrobulbar injection rather than general anesthesia. 

CPT code 66984 has 90 days (about one and a half weeks) global period.

If any Evaluation and management (E/M) service is perfumed in conjunction with CPT code 66984, modifier 24 will be reported with E/M service for an unrelated condition.

CPT 66984 Examples

There are the following examples of CPT 66984 when this service will be billed:
