Superficial siderosis of cerebral hemisphere

Created Jun 2010
Reviewed Dec 2019


Patient has ‘superficial siderosis of cerebral hemisphere’.  The only codes for siderosis in the classification are that for lung or eye.  The Neurologists I consulted said none of the possible codes (G31.-, G37.-, G93.8, G93.9, R29.88, R90.0, R90.8) are really appropriate.

However, in the absence of a better code he suggested that we use G93.8 Other specified disorders of brain and free text the code description.  Does NZCA agree?


Yes.  Agree G93.8 Other specified disorders of brain is the most appropriate code to assign for this condition.
Use free text to specify condition.
