E03.9 — Hypothyroidism
Denied44F · investigation — Repeat thyroid ultrasound
Insurer Rationale
Repeat thyroid ultrasound is not indicated in stable hypothyroidism without new structural symptoms or examination changes.
Reasoning Chain
This request would add noise, not clarity. Stable hypothyroidism with normalised TSH and no new palpable abnormality does not justify repeat imaging.
Reasoning Chain
Findings
Stable symptoms, Normal TSH on treatment, No new neck mass, No dysphagia
Diagnosis
Hypothyroidism (stable on therapy)
Assessment
Thyroid surveillance review — There is no structural trigger for repeat ultrasound in stable treated hypothyroidism.
Guideline action
Continue biochemical follow-up only unless new thyroid structural findings emerge
Verdict
Denial is clinically correct because routine repeat ultrasound adds little when thyroid function is stable and examination is unchanged.
Clinical Evidence
NICE Guideline NG145 — Thyroid disease
Monitoring treated hypothyroidism
Biochemical monitoring is standard; repeat ultrasound is reserved for structural concern rather than stable hypothyroidism alone.
British Thyroid Association Guidance (2024)
Imaging indications
Ultrasound is driven by nodule or compressive change, not routine surveillance of stable disease.
