Objectives The objective of this study was to examine the impact of the transition from International Classification of Disease Version Nine Clinical Modification (ICD-9-CM) to Interactional Classification of Disease Version Ten Clinical Modification (ICD-10-CM) on family medicine and identify areas where additional training might be required. Methods Family medicine ICD-9-CM codes were obtained from an Illinois Medicaid data set (113,000 patient visits and $5.5 million dollars in claims). Using the science of networks we evaluated each ICD-9-CM code used by family medicine physicians to determine if the transition was simple or convoluted.1 A simple translation is defined as one ICD-9-CM code mapping to one ICD-10-CM code or one ICD-9-CM code mapping to multiple ICD-10-CM codes. A convoluted transition is where the transitions between coding systems is non-reciprocal and complex with multiple codes where definitions become intertwined. Three family medicine physicians evaluated the most frequently encountered complex mappings for clinical accuracy. Results Of the 1635 diagnosis codes used by the family medicine physicians, 70% of the codes were categorized as simple, 27% of the diagnosis codes were convoluted and 3% were found to have no mapping. For the visits, 75%, 24%, and 1% corresponded with simple, convoluted, and no mapping, respectively. Payment for submitted claims were similarly aligned. Of the frequently encountered convoluted codes, 3 diagnosis codes were clinically incorrect, but they represent only < 0.1% of the overall diagnosis codes. Conclusions The transition to ICD-10-CM is simple for 70% or more of diagnosis codes, visits, and reimbursement for a family medicine physician. However, some frequently used codes for disease management are convoluted and incorrect, where additional resources need to be invested to ensure a successful transition to ICD-10-CM.

Background In India, approximately 75% of population that is over 650 million people have B12 deficiency majority of which is caused by variation in demography, diet, and religion. Conditions such as smoking, alcohol, and antacid use are certain causes for incidence of vitamin B12 deficiency. Looking at various adverse health effects of drinking demineralized water, there is possibility that it may also be one of the newly associated factors for increasing incidence and prevalence of vitamin B12 deficiency. Objective To assess the risk factors associated with vitamin B12 deficiency. Methods A case control study was conducted at SSG Hospital in Vadodara, Gujarat, wherein all the patients visiting the hospital from November 2017 to June 2018 with symptoms suggestive of B12 deficiency and serum B12 level below 200pg/mL were included in the study. Information regarding the vitamin B12 deficiency was obtained from the patients. Controls were selected and matched with cases as per age group to minimize confounding. Results Our study showed statistically significant association of vegetarian diet (p value=0.0027, OR=2.00) (odds ratio), dark complexion (0.0069, OR=2.53), socio economic status (p value= 0.0001), and use of RO (reverse osmosis) water (p value=0.0099, OR=3.61) with vitamin B12 deficiency at 95% CI (confidence interval). Conclusion Independent association between use of R.O. water, vegetarian diet, socio economic class, and dark complexion with vitamin B12 deficiency.
