Cataract Extraction Procedures


Today, in “Spotlight on CPT” the conversation will be on cataract extraction procedures.  It may seem that this should be a very straightforward procedure to code.  However, there are some variables that impact the correct CPT code assignment which we will examine today.

Most cataract removals are referred to ECCEs or extracapsular cataract extractions and are performed with the concomitant insertion of an IOL or intraocular lens.  When this procedure is performed, the CPT code assigned is 66984.  Modifiers should be appended as well to indicate the laterality of the procedure that was performed; RT, LT, or 50.  If the same procedure was performed via an intracapsular extraction, the code would be 66983.  The difference between extracapsular and intracapsular extraction is that when an extracapsular extraction is performed, only the lens material is removed with the posterior capsule remaining intact; whereas for intracapsular extraction, which is rarely performed, the entire capsule as well as the lens material is removed.      

As noted, the codes above will include the IOL insertion performed during the same encounter.  If the patient has to have the cataract removed and the IOL inserted at a separate encounter, the coding will change.  The appropriate cataract removal code will be found in the CPT range of 66840-66940 and should be assigned based on the method of extraction: aspiration, phacofragmentation, etc.  When the patient returns at a subsequent encounter for the IOL insertion, 66985 is the CPT code to assign.

Coding professional should be aware that there are a number of components that may be a part of a cataract surgery which can include lateral canthotomy, iridectomy, iridotomy, anterior capsulotomy, posterior capsulotomy, the use of viscoelastic agents, enzymatic zonulysis, use of other pharmacologic agents, and subconjunctival or sub-Tenon injections. The performance of any of these services is considered part of the overall cataract extraction procedure and should not be separately reported.  However, if a vitrectomy is performed at the same time as the cataract extraction, it is not considered part of the bundled services and an additional code for the vitrectomy should be added.

There are some occasions when cataract extractions become more complicated.  For example, the patient’s pupil may not dilate well or zonular dehiscence may occur during the procedure.  In either circumstance, either before the procedure actually begins or after the IOL has been inserted, if such a condition occurs, the surgeon may place a Malyugin ring  or a capsular tension ring, respectively.  The use of these devices will impact the CPT code choice, which will change to 66982.  This code is to be used when devices are used to expand the iris, sutures are used to support the lens, or in the event that a posterior capsulorrhexis must be performed.  The same code should be used if the cataract surgery is performed on a patient in the amblyogenic developmental stage. 

Just a quick word on zonular dehiscence or zonular dialysis.  This is a condition of the zonules of the eye (zonule of Zinn), which are fibrous bands that connect the lens with the ciliary body (see picture below).  This collection of bands, approximately 140, provides support to the lens.  If the zonules are damaged or weakened, subluxation of the lens can result.

Postprocedurally, if the intraocular lens becomes subluxated, repositioning may be needed.  For those procedures, CPT code 66825 should be assigned. 

Coding professionals should take care not to confuse initial cataract extractions with removal of secondary cataracts, which can also be termed after-cataracts or opacified posterior capsules.  Procedures for treatment of secondary cataracts depends on the method of removal; either via a stab incision (66820) or YAG laser (66821). 

One final tidbit of information.  In a 1st Qtr. 2007 Coding Clinic for HCPCS, a question about coding for limbal relaxing incisions performed during cataract surgery was posed.  The advice given was that limbal relaxing incisions are incidental to cataract extractions and therefore, not reported separately.  This procedure may be performed in patients who present with astigmatism.  If the procedure is performed independently, coding professionals are directed to use the unlisted code 66999 for reporting.

Now, light has been shed on coding for cataract extraction procedures.

Atrial Fibrillation


This In the kNOW” discussion will focus on the condition often shortened in medicine as a-fib or AF, but in actuality termed atrial fibrillation.  This condition is a type of cardiac arrhythmia affecting the atria or upper chambers of the heart.  Rather than pumping effectively, in patients with a-fib, the atria quiver and the heart is ineffective in moving blood out to the body.  When blood pools or collects in the heart, clots may form and therefore, patients with atrial fibrillation are at a high risk for strokes.
 
The symptomatology for atrial fibrillation is quite variable. Patients may experience dizziness, shortness of breath, rapid heartbeat, a fluttering sensation in the chest, overall fatigue, and even chest pain.  However, there are individuals with a-fib who do not exhibit any symptoms with the condition discovered on a routine physical exam.         

Risk factors for atrial fibrillation include underlying heart problems such as cardiomyopathy or valve issues.  Other chronic conditions such as hypertension, diabetes, hyperthyroidism, and asthma can all increase the risk of atrial fibrillation as does age, as an individual’s risk increases with age. Surprisingly, athletes, who we tend to think of as being in good physical condition, are at risk as they may have a type of rapid heartbeat known as supraventricular tachycardia, which can trigger a-fib.  Excessive alcohol consumption can also precipitate a-fib.  Finally, atrial fibrillation is a very common postoperative complication.


The treatments available for a-fib range from medication and lifestyle changes, to a variety of procedures, such as cardioversion, insertion of pacemakers, or electrophysiological ablation.


There are several different types of atrial fibrillation, and this year, the ICD-10-CM update makes some changes to the coding of this condition.  Let’s look at the different types of atrial fibrillation before exploring the coding changes.


Paroxysmal atrial fibrillation – generally lasts less than a week, may resolve on its own


Persistent atrial fibrillation – lasts longer than a week, may require medication or cardioversion treatment
 

Long-Standing Persistent atrial fibrillation – lasts more than a year, treatment with ablation may be necessary
 

Permanent (Chronic) atrial fibrillation – this type of atrial fibrillation is generally not correctable
 

Postoperative atrial fibrillation – occurs after a surgical procedure, medication is likely treatment
 

Acute Onset atrial fibrillation – occurs suddenly and generally resolves within a day or two

Coding professionals may often see the term “rapid ventricular response” or RVR noted alongside a diagnosis of atrial fibrillation.  This term indicates that the irregularity of the atria have affected the ventricles or lower heart chambers.  This results in the ventricles beating too fast.  RVR does not impact the assignment of the atrial fibrillation code as clarified in a Coding Clinic from 3rd Qtr. 2018.  Coders should assign the code for the type of atrial fibrillation documented by the physician.
Here is a comparison of the Alphabetic Index for atrial fibrillation from 2019 to 2020.  Coders can identify the changes at a glance.  While unspecified and paroxysmal atrial fibrillation codes remain the same, the codes for chronic, persistent, and permanent underwent changes with the additions of fifth digits.

Home Hazards

Test your ICD-10-CM coding skills with this Klutz family experience.

Since the Klutz children are in so many activities once spring arrives, Mr. and Mrs. Klutz decided to take advantage of a cold, snowy weekend in February to get some spring-cleaning chores out of the way around their single-family home.  Each of the children had a task to help with as well, and true to course, each child ended up with some injury.  Let us see what transpired.

Raymond was helping his father clean out the garage by holding a large box that his father was filling with items to throw away.  Raymond had both arms under the box, which became quite heavy, but he did not want to complain, so he held the box in the same position for an hour.  By the time Raymond put the box in the dumpster, he had strained both wrists from the rather awkward position he had kept the box in. 

Little Dana suffered a strain of her big toe when she fell out of a pair of her mother’s high-heeled shoes that were going to be thrown away.  Dana could not help but want to try on the fancy shoes when she was supposed to put them in the trash.  She took them to her bedroom so she could secretly wear them.  However, she misjudged how big the shoes were and walked into a dresser in her bedroom and then fell, injuring her left toe.    

Egon carried boxes of old clothes to the attic for his mother making multiple trips up the ladder and lifting the heavy boxes overhead.  He ended up with a right shoulder strain by the end of the day.
Janine was pitching in by scrubbing and then waxing the floors in the kitchen and both bathrooms.  For several hours, she was busily scrubbing and waxing using the circular motions her mother had taught her.  By late afternoon when she was finished, it was evident that she strained both of her biceps from the day’s work.

Peter’s contribution to the spring cleaning day was vacuuming all the carpets and rugs in the house, including the bedrooms, living room, dining room, and family room.  This took several hours as he moved the furniture to sweep behind and/or under it.  The constant reaching and repetitive movement took its toll on his low back, which ended up strained by day’s end.

The Klutz children were all glad when the annual spring-cleaning was finished…for this year!
