ICD-9 ICD-10 CM and PCS Codes Mapping

**Overview**
This accelerator contains information of ICD 9 and ICD 10 codes as these both codes are different in the fundamental structure and concepts. This accelerator help to understand the differences between them for a smooth transition from ICD-9 to ICD-10.

**Description**
The granularity of ICD-10-CM and ICD-10-PCS is vastly improved over ICD-9-CM and will enable greater specificity in identifying health conditions. It also provides better data for measuring and tracking health care utilization and the quality of patient care.

- The greater level of detail in the new code sets includes laterality, severity, and complexity of disease conditions, which will enable more precise identification and tracking of specific conditions.
- Terminology and disease classification are now consistent with new technology and current clinical practice.
- Injuries, poisonings and external causes are much more detailed in ICD-10-CM, including the severity of injuries, and how and where injuries happened. Extensions are also used to provide additional information for many injury codes.
- Pregnancy trimester is designated for ICD-10-CM codes in the pregnancy, delivery and puerperium chapter.
- Postoperative codes are expanded and now distinguish between intraoperative and post-procedural complications.
- There are new concepts that did not exist in ICD-9-CM, such as under dosing, blood type, the Glasgow Coma Scale, and alcohol level

**Benefits**
- Useful for physicians, coders and billing companies to understand icd-9, icd-10-cm and icd-10-pcs code as what conditions their members were treated for so that claims can be settled correctly.

**Included Datasets**
- [ICD Oncology Histology Validation List](https://www.johnsnowlabs.com/marketplace/icd-oncology-histology-validation-list)

This is called the PDX Exclusion List that identifies conditions that will not be considered a CC or MCC for a given principal diagnosis.

**Data Engineering Overview**
**We deliver high-quality data**
- Each dataset goes through 3 levels of quality review
- 2 Manual reviews are done by domain experts
- Then, an automated set of 60+ validations enforces every datum matches metadata & defined constraints
- Data is normalized into one unified type system
- All dates, unites, codes, currencies look the same
- All null values are normalized to the same value
- All dataset and field names are SQL and Hive compliant
- Data and Metadata
- Data is available in both CSV and Apache Parquet format, optimized for high read performance on distributed Hadoop, Spark & MPP clusters
- Metadata is provided in the open Frictionless Data standard, and its every field is normalized & validated
- Data Updates
- Data updates support replace-on-update: outdated foreign keys are deprecated, not deleted

**Our data is curated and enriched by domain experts**

Each dataset is manually curated by our team of doctors, pharmacists, public health & medical billing experts:
- Field names, descriptions, and normalized values are chosen by people who actually understand their meaning
- Healthcare & life science experts add categories, search keywords, descriptions and more to each dataset
- Both manual and automated data enrichment supported for clinical codes, providers, drugs, and geo-locations
- The data is always kept up to date – even when the source requires manual effort to get updates
