N.Y. Comp. Codes R. & Regs. tit. 4 § 58.3
A person found not eligible by the employee health service may appeal that determination to the Civil Service Commission. Such appeal shall be in writing and shall state the reasons why the individual believes that the determination of the employee health service is incorrect. An appeal must be received by the Civil Service Commission within 30 days of the date of the written notice of the determination by the employee health service. The commission shall consider such reasons, together with the report of the employee health service, in making its determination. The commission may designate a physician to examine the individual, other than the physician who first examined the person. The determination of the commission as to whether the person nominated for appointment pursuant to section 55-b or 55-c is eligible for appointment pursuant to section 55-b or 55-c of the Civil Service Law shall be a final determination within the meaning of article 78 of the Civil Practice Law and Rules.
