ICD-9-CM: 430 excluding 852.xx) were identified. Despite the lack of specific ICD code for non-aneurysmal SSAH (published estimates are 10-20% of SSAH cases), the use of this method was validated in multiple studies to identify aneurysmal SSAH with high sensitivity and specificity. The following patient related risk factors associated with SSAH were selected: age, sex, race, smoking, alcohol use, hypertension, anemia, thrombocytopenia, liver disease, long-term anticoagulation and longterm aspirin use. The analysis accounted for the HCUP-NIS sampling design and hospital trend weights. Cross-sectional rates were compared using the modified Rao-Scott Chi Square test with multivariable logistic regression statistical analysis to calculate adjusted odds ratios, using SAS Version 9.4. The data base excluded aneurysm anatomic features and diagnostic imaging modality. Results: Hospitalizations for 224,447 UCA and 143,874 SSAH from 2009-2014, were included in the study, accounting for 15 and 10 hospitalizations per 100,000 US population, respectively. When compared to UCA, hospitalizations for SAH occurred more frequently (in order of higher Odds Ratios) in males, absence of long-term aspirin, > 65 years, thrombocytopenia, non-whites and with anemia, alcohol abuse, and long-term use of anticoagulants (adjusted OR range: 1.02-2.17; all p < .001). Hypertension and liver disease were not significant. Conclusions: HCUP-NIS data identified patient-related factors associated with SSAH hospitalizations that may offer further risk stratification for screening and treatment for UCA, regardless of size and location, to further improve quality of care.

information required for accurate ICD-10-CM coding and the ways in which the required documentation differs from ICD-9-CM using examples specific to IR. We will also present strategies to improve accurate CPT and ICD-10 coding, including communication with coding teams and a structured template for E&M notes. A sample template which has been developed to be helpful to referring colleagues and professional coders while incorporating the requirements of the CPT codes for billing purposes will be included. Conclusions: Appropriate documentation of E&M services helps form relationships with referring physicians and can increase revenue at a time when reimbursement for procedures continues to decline. Accurate ICD-10-CM and CPT coding can be achieved through a better understanding of the terminology requirements, collaboration with coding teams and use of templates. References 1. CDC.

0-1.148mGy (mean 0.073mGy). The side of the face closer to the fluoroscope consistently record higher radiation doses than the opposite. Wearing lead glasses frequently did not result in significant decrease in eye dose. Conclusions: The side of the face closer to the fluoroscope consistently received higher radiation doses than the opposite. As opposed to optimized phantom studies, lead glasses did not consistently demonstrate a significant decrease in radiation dose to eyes. Orientation of the head to the radiation source appears to be critical and may significantly reduce the impact of leaded glasses. Barrier protection alone may be providing a false sense of security to the interventionist.
