Nystagmus and other irregular eye movements.
Medical necessity for evaluation and management of nystagmus and other irregular eye movements is established by the impact on visual function and quality of life.The need for diagnostic testing and treatment depends on the underlying cause and severity of the condition.
Diagnosis and management of nystagmus and other irregular eye movements falls under ophthalmologists, neuro-ophthalmologists, and sometimes neurologists, depending on the underlying cause. They assess the type and cause of the eye movements through clinical examination and may order further investigations like imaging or electronystagmography.
In simple words: This code refers to involuntary eye movements, where your eyes move on their own.This could be a condition present from birth or develop later due to various reasons.
This code encompasses various involuntary, rhythmic eye movements, including nystagmus.These movements can be horizontal, vertical, or rotational.They can affect one or both eyes and may be congenital or acquired.
Example 1: A 2-month-old infant presents with rhythmic, horizontal eye movements noticed since birth.The infant is diagnosed with congenital nystagmus (H55.01)., A 50-year-old patient with multiple sclerosis experiences new-onset vertical nystagmus, attributed to their underlying neurological condition (H55.04)., A 70-year-old patient exhibits involuntary eye oscillations after starting a new medication. This is documented as acquired nystagmus due to other causes (H55.05).
Documentation should include a detailed description of the eye movements (direction, speed, frequency), age of onset, associated symptoms (oscillopsia, vertigo), and any relevant medical history (neurological conditions, medications).Diagnostic tests, such as electronystagmography or imaging findings, should also be documented.
** Excludes certain conditions originating in the perinatal period (P04-P96), certain infectious and parasitic diseases (A00-B99), complications of pregnancy, childbirth and the puerperium (O00-O9A), congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99), diabetes mellitus related eye conditions (E09.3-, E10.3-, E11.3-, E13.3-), endocrine, nutritional and metabolic diseases (E00-E88), injury (trauma) of eye and orbit (S05.-), injury, poisoning and certain other consequences of external causes (S00-T88), neoplasms (C00-D49), symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94), and syphilis related eye disorders (A50.01, A50.3-, A51.43, A52.71).
