Is the treatment plan of azelastine, saline nasal rinses, and steroid nasal spray medically necessary for managing nasal obstruction and potential chronic sinusitis, considering previous use of Flonase (fluticasone propionate) and concerns about glaucoma?

Medical Necessity Assessment for Current Treatment Plan

The current treatment plan of azelastine nasal spray with saline rinses is medically necessary and represents standard of care for managing nasal symptoms, but septoplasty is NOT medically indicated based on the documentation provided, as the patient lacks objective evidence of nasal septal deviation or obstruction on examination.

Analysis of Medical Necessity

Current Conservative Management is Appropriate

The patient's current regimen of azelastine nasal spray combined with saline nasal rinses represents evidence-based, standard medical therapy for nasal symptoms and should be continued. 1

• Intranasal corticosteroids (like the previously used Flonase) combined with intranasal antihistamines (azelastine) provide superior symptom control compared to either agent alone, with 40% relative improvement over monotherapy 2
• The combination of azelastine plus fluticasone reduces Total Nasal Symptom Scores by 5.31-5.7 points compared to 3.25-4.54 for azelastine alone 2
• Saline nasal irrigation improves mucociliary clearance and is recommended as adjunctive therapy for chronic rhinosinusitis 1

Addressing the Glaucoma Concern

The provider's concern about daily Flonase use and glaucoma risk is not well-supported by high-quality evidence for intranasal corticosteroids. 1

• A systematic review concluded that nasal corticosteroids do not affect intraocular pressure or lens opacity 1
• Multiple randomized controlled trials found no increase in intraocular pressure with long-term intranasal corticosteroid use 1
• The systemic bioavailability of intranasal fluticasone propionate is less than 1%, making systemic side effects unlikely even at double the usual dose 3

If glaucoma concerns persist, the patient could safely return to combination therapy with fluticasone propionate plus azelastine, which provides superior efficacy to azelastine alone. 2, 4

Surgical Indication Assessment

Septoplasty is NOT medically indicated based on the provided documentation for the following reasons:

• Normal intranasal examination bilaterally: The clinical notes explicitly state "right intranasal examination normal without turbinate hypertrophy, masses, septal deformity or synechiae" and "left intranasal examination normal without turbinate hypertrophy, masses, septal deformity or synechiae"
• Milliman MCG criteria not met: The criteria require nasal septal deviation or septal spurring AND symptoms of nasal obstruction that interfere with lifestyle, but the examination shows no septal deformity [@question context@]
• Lack of objective confirmation: The patient has never had a CT scan of the sinuses to confirm chronic sinusitis, and the diagnosis remains uncertain [@question context@]
• Inadequate trial of medical therapy: While the patient used Flonase for "several months," there is no documentation of an adequate trial of combination therapy (intranasal corticosteroid plus intranasal antihistamine) which represents the most effective medical management 2

Standard of Care Determination

Medical Management is Standard of Care

The treatment plan using intranasal antihistamines and saline rinses is considered standard of care and is proven safe and effective based on current medical guidelines. 1

• The Journal of Allergy and Clinical Immunology practice parameters recommend intranasal corticosteroids as reasonable adjunctive therapy for sinusitis due to their recognized anti-inflammatory effect and documented efficacy in relieving nasal congestion 1
• The European Position Paper on Rhinosinusitis (2020) provides high-quality evidence that long-term use of nasal corticosteroids is effective and safe for treating patients with chronic rhinosinusitis 1
• Intranasal antihistamines like azelastine have clinically significant rapid onset of action (within 15 minutes) and are appropriate for managing nasal symptoms 1, 5, 6

Combination Therapy Recommendation

For optimal symptom control, the patient should be transitioned to combination therapy with azelastine plus fluticasone propionate nasal spray. 2, 4, 7

• The 2017 Joint Task Force on Practice Parameters provides a recommendation for using the combination of an intranasal corticosteroid and an intranasal antihistamine for initial treatment of moderate-to-severe symptoms 2
• Long-term safety studies demonstrate that combination azelastine-fluticasone therapy is well tolerated over 12 months with low incidence of treatment-related adverse events (9.4%) 4
• A recent comparative study showed combination fluticasone propionate with azelastine achieved significantly better symptom reduction (TSS 2.02 ± 0.83) compared to fluticasone alone (TSS 3.80 ± 1.49) after 4 weeks 7

Surgery is NOT Standard of Care in This Case

Functional endoscopic sinus surgery (FESS) is not indicated without documented anatomic abnormalities on examination or imaging, and when medical management has not been optimized. 8

• A randomized controlled trial demonstrated that treatment with fluticasone propionate nasal drops reduced the need for FESS in 13 of 27 patients (48%) versus 6 of 27 in placebo group, indicating that optimized medical therapy can obviate surgery 8
• The patient lacks CT confirmation of chronic sinusitis and has normal intranasal examination findings bilaterally [@question context@]

Clinical Algorithm for Management

Step 1: Continue azelastine nasal spray (current therapy) 5, 6

Step 2: Add back intranasal fluticasone propionate to create combination therapy, counseling patient that glaucoma risk is not supported by evidence 1, 2, 4

Step 3: Continue high-volume saline nasal irrigations 1

Step 4: Reassess symptoms after 12 weeks of optimized combination medical therapy 8, 4

Step 5: If symptoms persist despite optimized medical therapy, obtain CT scan of sinuses to objectively document chronic sinusitis and assess for anatomic abnormalities [@question context@]

Step 6: Only consider surgical referral if CT demonstrates significant disease AND medical therapy has failed AND examination reveals anatomic obstruction 8

Common Pitfalls to Avoid

• Premature surgical referral: Surgery should not be pursued without objective documentation of anatomic abnormalities and failure of optimized medical management 8
• Suboptimal medical therapy: Using azelastine alone when combination therapy with intranasal corticosteroid provides superior efficacy 2, 7
• Unsubstantiated glaucoma concerns: Discontinuing effective intranasal corticosteroid therapy based on theoretical glaucoma risk not supported by evidence 1
• Lack of objective confirmation: Proceeding with surgical planning without CT imaging to confirm chronic sinusitis diagnosis [@question context@]
