Healthcare providers treating urinary tract infections (UTIs) often need prior authorization (PA) for specific antibiotics like Fosfomycin Tromethamine. WellCare Medicare, a provider of Medicare Part D prescription drug coverage, requires PA for these antibiotics as a checkpoint to ensure the medication is appropriate for the patient’s medical history and current needs, especially when treating complex or persistent UTIs. Fosfomycin Tromethamine is a broad-spectrum antibiotic that is sometimes necessary for patients who haven’t responded well to other medications. However, WellCare requires clear documentation demonstrating why Fosfomycin is essential for the patient’s care. This guide will walk you through the PA process for Fosfomycin, from filling out the initial form to gathering supporting evidence.


Key Takeaways

  • Document Alternative Treatments: It’s crucial to provide a history of other antibiotics that were ineffective or caused side effects.
  • Provide Clinical Justification: Show that Fosfomycin has been effective in managing the patient’s infection and has a clear therapeutic purpose.
  • Submit Supporting Documentation: Including lab results and detailed medical history can help reinforce the necessity of Fosfomycin for the patient’s treatment plan.

Step-by-Step Process for Obtaining Prior Authorization

Here’s a detailed look at each step in obtaining PA for Fosfomycin Tromethamine under WellCare Medicare.

1. Initiating the PA Process

I began the PA process by accessing WellCare Medicare’s electronic PA form through CoverMyMeds. This platform simplifies the workflow by providing a structured, online system for PA submissions, which reduces manual entry and potential errors. By choosing the specific PA form for Fosfomycin, I was able to follow a guided path for entering information about the patient and the medication, which helps ensure that WellCare receives all the necessary details.

2. Entering Patient and Provider Details

This is where it’s important to be precise. WellCare uses these details to confirm eligibility, check the plan’s coverage requirements, and identify the patient’s prescriber if they need further clarification.

Patient Information: I documented essential patient details, including:

  • Name and Date of Birth: Confirms the patient’s identity.
  • Medicare ID: Verifies that the patient is enrolled in WellCare’s Medicare Part D plan.
  • Address and Contact Number: Ensures that WellCare can follow up if needed.

Having complete and accurate information here is essential for WellCare to process the request efficiently.

Provider Information: Next, I entered the prescribing provider’s details, including:

  • NPI (National Provider Identifier): This unique identifier links the request directly to the prescribing provider.
  • Name, Address, and Contact Information: WellCare may need to contact the provider for additional details or clarification, so accurate contact information is essential.

3. Filling in Drug-Specific Information

Medication Name: I indicated Fosfomycin Tromethamine as the requested medication.

Dosage and Quantity Requested: In this case, Fosfomycin was prescribed as a 3g sachet to be mixed with water, with a total quantity that reflects a single-dose treatment typical for UTI management. These details help WellCare evaluate whether the requested amount aligns with standard treatment guidelines.

4. Answering Clinical Questions

This section is where we make the case for why Fosfomycin is necessary and provide WellCare with the background they need to approve the request.

Primary Diagnosis: I specified Urinary tract infection (UTI), along with details about the type of infection and the patient’s need for an effective antibiotic. This diagnosis shows that the patient has an active infection that requires treatment with an antibiotic, particularly when other options haven’t worked.

Patient Age Verification: Since the patient was over 65, I confirmed their age on the PA form. Age can sometimes impact medication choices, especially with antibiotics, as older patients may be more sensitive to certain medications. This ensures WellCare is aware of any added precautions in the treatment plan.

Efficacy of Alternative Treatments: WellCare’s PA form also required details on prior treatments. I documented that the patient had previously tried multiple antibiotics, including:

  • Ciprofloxacin: A standard UTI antibiotic that did not fully resolve the infection.
  • Doxycycline: Another commonly prescribed antibiotic that had minimal effect on the infection.
  • Nitrofurantoin: A standard first-line antibiotic for UTIs, but the patient experienced side effects that made it intolerable.

Providing a clear record of alternative treatments helps establish that Fosfomycin is necessary, not just as a preferred choice but as a critical solution after other options have failed.

5. Documenting Patient Stability on Fosfomycin

Now it’s time to explain why Fosfomycin is the best choice for the patient’s ongoing care. Here’s how I justified the need:

Stability and Effectiveness: I noted that since starting Fosfomycin, the patient’s infection has shown signs of improvement and stabilization without adverse reactions. Highlighting the effectiveness of the medication in managing the infection helps WellCare see that this isn’t a trial-and-error attempt but a carefully considered choice based on positive results.

Requesting Standard Review Time Frame: Since the patient’s condition was stable with the current medication, I opted for a standard review rather than an expedited one. This ensures WellCare can process the request in their normal timeframe without the additional urgency of an expedited review.

6. Submitting Supporting Documentation

To strengthen the PA request, I attached several key pieces of documentation:

  • Prescription Summary: This outlined the dosage and quantity of Fosfomycin requested.
  • Lab Results: Recent lab results showed the patient’s infection status and demonstrated the need for continued treatment.
  • Previous Treatment History: I included records of the patient’s prior medications, illustrating the limited efficacy and/or adverse reactions with previous antibiotics.

These documents collectively reinforce the case that Fosfomycin is not only effective but necessary for the patient’s UTI treatment. After ensuring everything was complete, I submitted the PA form to WellCare, which confirmed receipt and scheduled a prompt review.


ICD and CPT Codes Explanation

  • ICD-10 Code N39.0: This diagnosis code, for urinary tract infection, is important in establishing the clinical need for an antibiotic like Fosfomycin, especially when previous treatments have been unsuccessful.

Frequently Asked Questions (FAQs)

Q1: Why is Fosfomycin Tromethamine prescribed for urinary tract infections?
A1: Fosfomycin is effective against bacterial infections in the urinary tract, especially in cases where first-line antibiotics have failed or caused side effects.

Q2: What documentation does WellCare Medicare require for PA approval of Fosfomycin?
A2: WellCare requires details on the patient’s UTI diagnosis, prior antibiotic treatments, and evidence that Fosfomycin has been effective in managing the infection.

Q3: Is an expedited review necessary for Fosfomycin in UTI cases?
A3: Expedited reviews are typically reserved for urgent cases where a delay could worsen the patient’s health. In this instance, since the patient was stable, a standard review was appropriate.


What Did We Learn?

The case study on Fosfomycin highlights the importance of detailed documentation in patient care, especially when a patient has limited success with other antibiotics. A complete history of alternative treatments and a record of the patient’s stability on Fosfomycin supported the case for prior authorization, allowing for a smoother PA process with minimal delays.
