Classification and alternative names
"Patients with MUS or MUPS are sometimes referred to as having Functional Somatic Symptoms (FSS) or diagnosed as Bodily Distress Disorder (BDD) - both of which are mental illnesses - despite being classified as physical illnesses under the World Health Organization's current ICD-10 classification, and the latest ICD-11 classification."

Comment: There is no term "Functional Somatic Symptoms" in ICD-10. ICD-10 has a Somatoform disorders category block (F45.0-F45.9). The various ICD-10 Somatoform disorders categories are not classified as "physical illnesses" in ICD-10 - they are classified as mental disorders in ICD-10 Chapter V: Mental and behavioural disorders.

"Bodily distress disorder" is an ICD-11 category, but again it is not classified as a "physical illness" in ICD-11. "Bodily distress disorder" is classified as a mental disorder in ICD-11 Chapter 06 Mental, behavioural and neurodevelopmental disorders.

Possibly the author had intended to write:

Patients with MUS or MUPS are sometimes referred to as having Functional Somatic Symptoms (FSS) or diagnosed as Bodily Distress Disorder (BDD) - both of which are mental illnesses [- despite having diseases or conditions that are] classified as physical illnesses under the World Health Organization's current ICD-10 classification, and the latest ICD-11 classification.

But it is unclear what the author intended.

"Somatoform disorders, Somatic symptom disorders, Conversion disorder, and Functional Neurological Disorder (FND) are also regarded as medically unexplained symptom and classified as purely psychological symptoms conditions only in the DSM psychiatric manual.[4][5]"

Comment: There are no Somatoform disorders in DSM-5. The DSM-IV TR Somatoform disorders are obsolete and were replaced with Somatic symptom disorder for DSM-5.

DSM-IV TR had included a category Conversion disorder. The term Conversion disorder was replaced for DSM-5 with the term, "Conversion disorder (functional neurological symptom disorder)".
