Billing for the OBGYN surgical procedures is as difficult as billing for other medical procedures. The surgeons face various challenges and claim denials when collecting reimbursement for their services. Keeping these challenges in mind, we have decided to discuss one of the common OBGYN procedural codes, i.e., CPT code 58661.
In this comprehensive guide, we will discuss the code’s official description with clinical scenarios and applicable modifiers. If you are looking for reimbursement guidelines for CPT code 58661, continue reading.
CPT Code 58661 – Description
In medical billing, CPT code 58661 refers to a laparoscopic surgical procedure in which adnexal structures are removed (salpingo-oophorectomy).
The surgery is performed by a surgeon specialized in laparoscopic procedures, where he removes one or both ovaries and/or fallopian tubes with minimal invasion. This surgery is usually performed to treat various diseases affecting the fallopian tubes or ovaries.
Appropriate Use Cases for CPT Code 58661
The following are clinical examples of some gynecological diseases that are treated with a laparoscopic procedure and must be billed with CPT code 58661.
Ovarian Cysts
Suppose a patient comes with bloating, irregular menstruation periods, and significant pelvic pain for a few months. Her gynecologist performs an ultrasound and discovers a growing ovarian cyst on the left ovary. The physician decides to perform a laparoscopic procedure to remove the affected ovary and fallopian tube because the cyst is causing severe discomfort and could harm the ovary.
Since the surgeon will use a minimally invasive laparoscopic technique to remove the left ovary, CPT code 58661 is best suited for billing in this case.
Endometriosis
A woman in her late thirties has been dealing with infertility, difficult periods, and persistent pelvic pain for years. The physician diagnoses endometriosis, which is significantly affecting the fallopian tubes and ovaries. The ovary is so compromised by scar tissue and endometrial implants that it is unable to function normally.
Hence, the only solution is to remove the ovary and fallopian tube using laparoscopic surgery. This case can be billed under CPT code 58661 because the procedure involves laparoscopic excision of adnexal structures like the ovary and fallopian tube.
Modifiers to Append with CPT Code 58661
The following are some of the modifiers that apply to CPT code 58661, based on the specific circumstances.
Modifier 50
Modifier 50 indicates a bilateral procedure. If the provider removed both ovaries and both fallopian tubes in the same session using a laparoscope, then he must append modifier 50 to code 58661. It will result in 150% of the physician fee schedule amount.
Modifier LT
Report the CPT code 58661 with modifier LT if the physician removed the ovary and/or the fallopian tube from the left side of the body.
Modifier RT
Report the CPT code 56881 with a modifier RT if the ovary and/or the fallopian tube was removed from the right side of the body.
Assistant at Surgery Modifiers (80, 81, 82, and AS)
You may apply ‘assistant at surgery’ modifiers to CPT code 58661, such as:
- 80: If an assistant surgeon provided full assistance during surgery.
- 81: If a physician provided minimal or partial assistance during surgery.
- 82: If the physician provided surgical assistance in a teaching hospital where a qualified resident was unavailable.
- AS: If a non-physician assisted during surgery.
You must apply the modifier that fits perfectly to your case.
Reimbursement Guidelines for CPT Code 58661
The following are some of the billing tips and reimbursement guidelines that you should bear in mind when filing claims with code 58661.
Avoid Usage for Obstetric Laparoscopy
CPT 58661 is typically not used for obstetric cases, like an ectopic pregnancy, where a ruptured fallopian tube requires removal. This is because, in such cases, more specific codes are available. Using 58661 here would most likely result in a claim denial.
Provide Complete Documentation
Include the following details in the paperwork of CPT code 58661 to prevent the risk of denial from your payer.
- Clearly justify the medical necessity in documents through proper diagnostic codes.
- Mention the exact condition and the reason that led to surgery.
- Mention that the surgery was minimally invasive.
- Specify the removed structures (ovary, fallopian tube, or both).
- And lastly, mention the sides on which the physician performed the removal with proper modifiers LT, RT, or 50.
Apply Correct Modifier(s)
There is a great debate on the internet about whether you should append the modifier 50 or not. Let’s find out. Modifier 50 is used to indicate a bilateral procedure. CPT code 58661 refers to a unilateral procedure. Therefore, billers must append modifier 50 if a surgeon removes both tubes. The claims will be denied without a proper modifier.
Review Payer’s Policies
Insurance payers differ significantly from one another in their payment policies and requirements. This differentiation compels billers to stay abreast of each payer’s changing rules. These policies may differ in the use of modifiers, reimbursement rates, or documentation requirements. Before billing for the CPT code 58661, review the payer’s policy manual to confirm specifics, such as whether a prior authorization is required, to ensure compliance with their payment rules.
Final Thoughts
We have covered almost every aspect of CPT code 58661. This brings us to the end of our reading. But before we go, let’s review what we have learned. This code describes a laparoscopic procedure, the surgical removal of the ovaries and/or fallopian tubes.
In the real-life scenarios we mentioned above, we discussed examples of ovarian cyst and endometriosis, where this code is applicable. Be sure to append the most appropriate modifiers when necessary and follow the essential billing and reimbursement guidelines to avoid claim denials.
