Hi Pat burton3
"Entitlement' to PIP only refers to a small number of people who have been given a terminal diagnosis and less than 6 months to live. So it's not just your diagnosis but how it impacts your daily living and mobility, as laid down in the PIP criteria. It is quite possible for two people to appear to have the same condition, one person to be awarded PIP and another not, or one person to have a standard award and another enhanced.
The fact that you have broken your hips twice - won't automatically entitle you to an increased award. However, you can put in for a change of circumstances and they will send you out a review form. On that form, you should detail the deterioration of your mobility due to your osteoporosis and any other conditions and make the case for where you believe you should receive a higher award. Don't just focus on your broken hips - because the DWP will try and argue that your hips have mended. I'm not saying you shouldn't mention them, of course, you will, because it shows the picture of your deterioration, but make sure you also include the day-to-day difficulties against the specific PIP criteria.
