I am in the process of rewriting the entire hccpy incorporating all the feedback and issues in the past. If you want to provide mode thoughts while I am in the process, please reach out to me on LinkedIn (https://www.linkedin.com/in/yubin-park-phd/) - the fastest way to reach me.
The new project will be hosted by https://github.com/mimilabs - for more details, please see: https://www.mimilabs.ai/projects/65e908d2972dde0f134d21db

Hierachical Condition Categories Python Package.
This module implements the Hierachical Condition Categories that are used for adjusting risks for the Medicare population. The original SAS implementation can be found here.
The latest version is 0.1.10 which was released on 04/10/2024.
Currently, hccpy supports:
- CMS-HCC V22
- CMS-HCC V23
- CMS-HCC V24
- CMS-HCC V28
- CMS-HCC ESRD
- HHS-HCC 2019 (V05)
- HHS-HCC 2022 (V07)
Note that hccpy does not have support for ICD-9.
Installing from the source:
$ git clone git@github.com:yubin-park/hccpy.git
$ cd hccpy
$ python setup.py develop
Or, simply using pip
:
$ pip install hccpy

hccpy
is really simple to use.
Please see some examples below:
To import the HCCEngine
class from hccpy
:
>>> import json
>>> from hccpy.hcc import HCCEngine
>>> he = HCCEngine()
>>> print(he.profile.__doc__)
Returns the HCC risk profile of a given patient information.

To get a HCC profile from a list of diagnosis codes (in ICD-10):
>>> rp = he.profile(["E1169", "I5030", "I509", "I211", "I209", "R05"])
>>> print(json.dumps(rp, indent=2))
{
"risk_score": 1.3139999999999998,
"details": {
"CNA_M70_74": 0.379,
"CNA_HCC85": 0.323,
"CNA_HCC88": 0.14,
"CNA_HCC18": 0.318,
"CNA_HCC85_gDiabetesMellit": 0.154,
"CNA_DIABETES_CHF": 0.0
},
"hcc_lst": [
"HCC85",
"HCC88",
"HCC18"
],
"hcc_map": {
"I5030": "HCC85",
"I209": "HCC88",
"E1169": "HCC18",
"I509": "HCC85"
},
"parameters": {
"age": 70,
"sex": "M",
"elig": "CNA",
"medicaid": false,
"disabled": 0,
"origds": 0
}
}
>>>
Please use "V28" when initializing the engine.
>>> from hccpy.hcc import HCCEngine
>>> he = HCCEngine("28")
Also, see the test_v23()
examples in tests/hcc_tests.py
.
You can add normalization factors and coding intensity factors to directly calculate the adjusted risk score.
By default, these two parameters are set as:
cif = 0.059, # coding intensity factor.
norm_params={
"C": 1.015, # community/institution models
"D": 1.022, # ESRD Dialysis
"G": 1.028 # ESRD Graft
}
You can overwrite these parameters. For example, this setting below would not adjust the raw risk score.
HCCEngine(version="28", cif = 0, norm_params={"C": 1})
To see the adjusted risk scores,
>>> from hccpy.hcc import HCCEngine
>>> he = HCCEngine("28")
>>> rp = he.profile(["E1169", "I5030", "I509", "I211", "I209", "R05"],
age=70, sex="M", elig="CNA")
>>> rp["risk_score_adj"]
Also, see the test_norm_factors()
examples in tests/hcc_tests.py
.
If a member is new, then provide the elig="NE"
in the input:
>>> rp = he.profile([], elig="NE", age=65)
>>> print(json.dumps(rp, indent=2))
{
"risk_score": 0.514,
"details": {
"NE_NMCAID_NORIGDIS_NEM65": 0.514
},
"hcc_lst": [],
"hcc_map": {},
"parameters": {
"age": 65,
"sex": "M",
"elig": "NE_NMCAID_NORIGDIS_NE",
"medicaid": false,
"disabled": 0,
"origds": 0
}
}
>>>
If a member has a different eligibility status, change the eligibility as follows (e.g. institutionalized member):
>>> rp = he.profile(["E1169", "I5030", "I509", "I209"], elig="INS")
>>> print(json.dumps(rp, indent=2))
{
"risk_score": 2.6059999999999994,
"details": {
"INS_M70_74": 1.323,
"INS_HCC88": 0.497,
"INS_HCC18": 0.441,
"INS_HCC85": 0.191,
"INS_HCC85_gDiabetesMellit": 0.0,
"INS_DIABETES_CHF": 0.154
},
"hcc_lst": [
"HCC88",
"HCC18",
"HCC85"
],
"hcc_map": {
"I209": "HCC88",
"E1169": "HCC18",
"I509": "HCC85",
"I5030": "HCC85"
},
"parameters": {
"age": 70,
"sex": "M",
"elig": "INS",
"medicaid": false,
"disabled": 0,
"origds": 0
}
}
To get the description, hierarchy parents and children of a HCC:
>>> hcc_doc = he.describe_hcc("HCC19") # either "HCC19", "hcc19" or "19"
>>> print(json.dumps(hcc_doc, indent=2))
{
"description": "Diabetes without Complication",
"children": [],
"parents": [
"HCC17",
"HCC18"
]
}
Not all claims are eligible for risk adjustment. For professional claims, a certain set of CPT codes is required to be eligible, while for institutional claims, a certain set of bill types is needed. This module provides an easy interface for determining if a certain claim is eligible for risk adjustment or not.
NOTE: This function uses CPT codes, and this requires AMA CPT license. Once you carefully review the license, you need to download a data file.
>>> from hccpy.raeligible import RAEligible
>>> rae = RAEligible()
>>> rae.load(fn="CY2019Q2_CPTHCPCS_CMS_20190425.csv")
>>> rae.is_eligible(pr_lst=["C5271"])
True
>>> rae.is_eligible(pr_lst=["C5270"])
False
>>>
NOTE: The data file (CY2019Q2_CPTHCPCS_CMS_20190425.csv
) should be located in the same folder.
