Minor oddities in d_icd_diagnoses: same long_title for multiple ICD-9 codes

This actually looks like a bug in the ICD-9 coding standard, since I find the same sharing of long_title for a few different codes from the CMS https://www.cms.gov/Medicare/Coding/ICD9ProviderDiagnosticCodes/codes

select long_title, group_concat(distinct icd_code), group_concat(distinct icd_version), count(*) c from d_icd_diagnoses group by long_title, icd_version  having c>1;

Start by rerunning the provided query against d_icd_diagnoses and compare the duplicate long_title values and ICD-9 codes with the linked CMS coding source. Determine whether the duplicates reflect source-standard behavior or an error in the repository data; done means documenting that conclusion and identifying any required correction.
