Choose The Most Appropriate Code with an Optometrist Expert Help

Even small ophthalmology practices are likely to have a Humphrey visual field analyzer, yet many ophthalmologists don’t know the secrets for securing adequate reimbursement for these services — and they even go so far as to put themselves at risk for costly audits due to lack of documentation.

CPT lists three different visual field examinations — and the higher the code, the higher the reimbursement.:

  • 92081 — Visual field examination, unilateral or bilateral, with interpretation and report; limited examination (e.g., tangent screen, Autoplot, arc perimeter or single stimulus level automated test, such as Octopus 3 or 7 equivalent)
  • 92082 — … intermediate examination (e.g., at least 2 isopters on Goldmann perimeter, or semiquantitative, automated suprathreshold screening program, Humphrey suprathreshold automatic diagnostic test, Octopus program 33)
  • 92083 — … extended examination (e.g., Goldmann visual fields with at least 3 isopters plotted and static determination within the central 30 degrees, or quantitative, automated threshold perimetry, Octopus program G-1, 32 or 42, Humphrey visual field analyzer full threshold programs 30-2, 24-2 or 30/60-2).

A common mistake ophthalmologists make is billing 92082 when they could legitimately bill 92083.

The key to choosing the correct VF code is in the code descriptors themselves. For example, if the ophthalmologist plots only two isopters on the Goldmann perimeter, CPT would call that “intermediate,” based on its description of 92082. If you plotted three isopters, however, that would be an “extended” examination that would qualify for 92083.

Rule of thumb: An intermediate test is one of the screening tests that you would use if you suspect neurological damage. But ophthalmologists use the threshold exam (92083) when they suspect something that causes a slow, progressive dimming of peripheral vision, like glaucoma. Glaucoma causes a loss of vision like a light bulb slowly becoming...

Know When to Append Modifier 50 on Bilateral CTS Shots

Your orthopedist injects both of a patient’s wrists to treat carpal tunnel syndrome. Should you just file 20526 with modifier 50 appended and forget about it? Not so fast: If the physician injects both the patient’s wrists to treat CTS, you will ty...

Emergency Reporting: Know When To Use +99140 With These Tips

Reporting any qualifying circumstances (QC) codes for anesthesia can be tricky, but knowing when to classify a situation as a true emergency can be a real challenge unless you’re well-versed in the emergency conditions guidelines. Check coding definitions and your provider’s documentation to know whether you can legitimately add two extra units for +99140 (Anesthesia complicated by emergency conditions [specify] [List separately in addition to code for primary anesthesia procedure]) to your claim.

CPT includes a note with +99140 stating that “an emergency is defined as existing when delay in treatment of the patient would lead to a significant increase in the threat to life or body parts.” Your key to knowing a case meets emergency conditions lies in your anesthesiologist’s notes.

“Quite a number of cases come in where the anesthesiologist marks ‘emergency’ but many times the ‘emergency’ isn’t all that clear,” says Leslie Johnson, CCS-P, CPC, director of coding and education for Medi-Corp., Inc., of New Jersey. Documentation supporting an emergency will depend on each case, so read the chart thoroughly when your provider indicates an emergency.

Solution: Talk with your anesthesia providers to clarify what constitutes an emergency and when you can include +99140. If there’s a real reason to report an emergency (such as a ruptured appendix, 540.0), your physician should clearly document the reason. Another diagnosis code to indicate a problem (such as unstable angina, 411.1) could help show the payer you’re reporting an unusual situation. The second diagnosis can also help in an appeal if a payer that ordinarily recognizes +99140 denies the claim.

“An OB patient who comes in for a cesarean section isn’t automatically an emergency,” explains Scott Groudine, M.D., professor of anesthesiology at Albany Medical Center in New York. “However, a diagnosis of fetal distress and prolapsed cord virtually always...
