If it isn't in the Schedules, then it isn't reportable. Depending on who the Doctor is, it might not even be HAVS. Occ.Health testing is very subjective - diagnosis can be reversed!

Just noted this thread. Hope this helps, although a little late for timescales under RIDDOR. Para 94, 250 & 319 from the guidance to the Control of Vibration at Work Regulations 2005 (Hand Arm Vibration) provide clarification, although reference RIDDOR 95 (Extracts from Schedule 3, Part 1: Occupational diseases, which would have been the 2nd Edition 1999. 94 - The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR) require employers to report to the enforcing authority any diagnosed cases of hand-arm vibration syndrome (HAVS) arising from certain work activities.11 If your business involves any of these activities (see the list in Appendix l), all of which are known to be associated with HAVS, you should assume you have a potential problem with vibration and that a programme of control measures and health surveillance may be required. 250 - The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 1995 (RIDDOR) place a duty on you as an employer to report any cases of HAVS arising from certain work activities or of carpal tunnel syndrome associated with exposure to vibration. The duty comes into effect when you receive a formal written diagnosis from a doctor confirming that the employee has either of these conditions and that there is reason to believe that the disease is likely to have an occupational origin. Before reporting HAVS to the Incident Contact Centre (Tel: 0845 300 9923 or website www.riddor.gov.uk), you should check that the employee is currently doing a job involving one of the specific activities listed in Schedule 3 of RIDDOR (see Appendix 1). You are also required to keep details of any report you make for at least three years. 319 - When cases of the occupational diseases, HAVS and carpal tunnel syndrome in association with vibration are diagnosed by a doctor, they should be reported by the employer in accordance with regulation 5 and Schedule 3 of the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) 1995. Guidance to RIDDOR 95 (4th edition published 2012) still includes HAVS as an Occupational Disease in Schedule 3, Part 1. Colum 2 of Schedule 3 for HAVS states as follows; Workers whose hands are regularly exposed to high vibration, for example in industries where vibratory tools and machines are used, may suffer from several kinds of injury to the hands and arm including impaired blood circulation and damage to the nerves and muscles. The injuries collectivelyare known as ‘hand-arm vibration syndrome’. Other names used in industry include vibration white finger, dead finger, dead hand and white finger. The severity of the vascular and neurological effects is indicated using an agreed classification system, the Stockholm Workshop Scales. More information on this and HAVS is contained in HSE guidance Hand-arm vibration.10 Collectively are known as ‘hand-arm vibration syndrome’. Other names used in industry include vibration white finger, dead finger, dead hand and white finger. The severity of the vascular and neurological effects is indicated using an agreed classification system, the Stockholm Workshop Scales. More information on this and HAVS is contained in HSE guidance Hand-arm vibration. In summary the case should be notified under RIDDOR to the Incident Contact Centre. In addition a review of the relevant risk assessment and management controls for HAVS should be conducted
