Chronic rhinosinusitis (CRS) — persistent inflammation of the nasal passages and paranasal sinuses lasting more than 12 weeks — is one of the most common chronic conditions affecting South African adults. From a medical aid perspective, CRS is not a CDL condition and is not PMB for routine management. The critical exception: FESS (functional endoscopic sinus surgery), when indicated, IS a PMB Diagnosis and Treatment Pair. Understanding this distinction shapes the entire cost picture.
What Is Chronic Sinusitis?
The sinuses are air-filled cavities in the facial bones (maxillary, frontal, ethmoid, sphenoid) lined with mucosa. When the mucosa becomes persistently inflamed — from allergy, infection, structural obstruction, or polyps — chronic rhinosinusitis develops.
Two main types: - CRS without nasal polyps (CRSsNP): Often driven by recurrent infection, allergy, or anatomical obstruction - CRS with nasal polyps (CRSwNP): Often associated with asthma and aspirin sensitivity (Samter's triad); polyps can cause significant nasal obstruction
Symptoms (at least 12 weeks): Nasal congestion/blockage, mucopurulent nasal discharge (anterior or post-nasal drip), facial pain/pressure/fullness, reduced or absent sense of smell (hyposmia/anosmia)
Diagnosis: Clinical assessment + endoscopy or CT scan of sinuses. CT of the paranasal sinuses is the gold standard — shows sinus opacification, mucosal thickening, anatomical variants (deviated septum, turbinate hypertrophy).
Is Chronic Sinusitis a PMB or CDL Condition?
Chronic sinusitis is NOT on the CDL and is NOT a standard PMB condition for routine management.
All day-to-day management — GP visits, nasal sprays, antibiotics, allergy testing — comes from your day-to-day benefit, MSA, or ATB.
Critical exception: FESS (functional endoscopic sinus surgery) — when medically indicated for CRS unresponsive to appropriate medical management — IS a PMB Diagnosis and Treatment Pair.
Your scheme must fund FESS when: - Documented failure of adequate medical management (nasal corticosteroids + saline irrigation ± antibiotics, typically 8–12 weeks) - CT sinuses confirming chronic sinusitis with obstructive features - ENT specialist referral confirming surgical indication
How Does Medical Aid Cover Chronic Sinusitis?
| Service | PMB/CDL? | Typical cover | Notes |
|---|---|---|---|
| GP consultation | No | Day-to-day | |
| CT paranasal sinuses | No (routine) | Radiology benefit — varies | Usually day-to-day; scheme may cover if FESS pre-auth pending |
| Nasal endoscopy | No (routine) | Day-to-day / ENT benefit | Done in ENT rooms |
| Intranasal corticosteroid (Flixonase, Nasonex, Avamys) | No | Day-to-day | R200–R500/month; effective, inexpensive |
| Saline nasal irrigation (sinus rinse) | No | OOP | Nasal Rinse/Neti pot: R80–R200 OTC |
| Antibiotic course (acute exacerbation) | No | Day-to-day | |
| Allergy skin-prick testing | No | Day-to-day | Identifies allergic triggers |
| Allergen immunotherapy (allergy shots) | No | Day-to-day — specialist | R800–R2,000/month initially |
| FESS (functional endoscopic sinus surgery) | Yes — PMB (DTP) | Hospital benefit | Requires documented medical failure + CT confirmation |
| Septoplasty (for deviated septum) | Yes — PMB (if contributing to CRS) | Hospital benefit | Often combined with FESS |
| Turbinoplasty (turbinate reduction) | Yes — PMB (if indicated) | Hospital benefit | Often combined with FESS |
| Nasal polyp removal | Yes — PMB (CRS with polyps, indicated surgery) | Hospital benefit | Polyps often recur; biologics for severe CRSwNP |
| Dupilumab (Dupixent — for severe CRSwNP) | No (routine) | Exceptional-needs consideration | R15,000–R20,000/month; not CDL; exceptional-needs pre-auth required |
| Post-FESS saline irrigation + nasal spray | No | Day-to-day | Essential for post-operative wound healing |
Medical Management First — Before Surgery
Before FESS is considered, your ENT specialist must document failure of appropriate medical management:
-
Intranasal corticosteroid spray (fluticasone, mometasone, budesonide) — first-line. Must be used correctly (aim away from the nasal septum, sniff gently) and consistently for at least 8–12 weeks. Generic fluticasone: R150–R250/month.
-
Saline nasal irrigation (isotonic or hypertonic saline rinse) — mechanical cleansing of the sinuses; improves mucociliary clearance. Very effective as an adjunct; inexpensive.
-
Antibiotics — for documented bacterial exacerbations. Prolonged low-dose macrolide therapy (azithromycin 3×/week or roxithromycin daily) is used for CRSsNP refractory to standard treatment — this is a medical management step, not a routine antibiotic course.
-
Allergy management — if allergy is a driver (CRS + allergic rhinitis crossover), treating the allergy reduces CRS exacerbations. See the Allergic Rhinitis article.
-
Short course of oral corticosteroids — for CRSwNP or severe exacerbations; reserved for specific situations; day-to-day.
Document all of this. Your ENT surgeon needs to submit this history with the FESS pre-auth.
FESS — What Is It?
FESS (functional endoscopic sinus surgery) is a minimally invasive procedure performed under GA through the nostrils — no external incisions. The ENT surgeon uses a small camera (endoscope) and fine instruments to: - Open blocked sinus drainage pathways - Remove polyps - Correct anatomical obstruction - Improve ventilation and drainage of the paranasal sinuses
Most patients go home same day or the following morning. Recovery: 1–2 weeks. Post-operative saline irrigation is critical for healing.
FESS is not a cure for CRS — it improves drainage and reduces severity. Ongoing medical management (nasal sprays, saline) is required indefinitely.
Day-to-Day Costs: What to Budget For
| Scenario | Estimated costs |
|---|---|
| Annual medical management (sprays, GP, allergy testing) | R4,000 – R12,000/year |
| CT paranasal sinuses (pre-FESS) | R2,500 – R5,000 |
| FESS (bilateral, private hospital) — gap shortfall | R10,000 – R40,000 (ENT surgeon + anaesthesiologist shortfall) |
| Post-FESS care (sprays, irrigations, follow-up endoscopy) | R2,000 – R5,000/year |
| Dupilumab (CRSwNP, severe, if funded) | R15,000 – R20,000/month — exceptional |
Cross-Reference
Many CRS patients also have allergic rhinitis — see the Allergic Rhinitis article for allergy management coverage details. Patients with CRSwNP often have asthma — see the Asthma article.
Key Questions to Ask Your Scheme
- Is FESS pre-authorised as a PMB DTP given my documented failed medical management? Ensure the clinical motivation is submitted.
- Is the CT paranasal sinuses covered prior to FESS pre-auth? It should be as a diagnostic for surgical planning.
- Does the FESS pre-authorisation include septoplasty and turbinoplasty if done simultaneously? Get written confirmation.
- Is gap cover notified for FESS? ENT shortfalls are significant.

FESS is a PMB procedure but requires documented medical failure — the most common reason for pre-auth decline is insufficient documentation of prior medical management. AURA helps build the clinical record and ensures FESS is pre-authorised correctly.
