Medical PMPM

Per Member Per Month (PMPM) spend is the starting point for any claims based analysis.

Calculate Member Months and Total Medical Spend

Select 
data_source
, year_month
, cast(sum(medical_paid) as decimal(18,2)) as medical_paid
, count(*) as member_months
, cast(sum(medical_paid)/count(*) as decimal(18,2)) as pmpm

Trending PMPM by Service Category

The pmpm table already breaks out pmpm by service category and groups it at the member month level.

Trending PMPM by Claim Type

Here we calculate PMPM manually by counting member months and joining payments by claim type to them.

with mm as 
(
select 
data_source
,year_month
,count(*) as member_months
from financial_pmpm.member_months
group by 
data_source
,year_month
)

,medical_claims as (
select 
  mc.data_source
  , to_char(claim_start_date, 'YYYYMM') AS year_month
  , claim_type
  , cast(sum(paid_amount) as decimal(18,2)) AS paid_amount
from core.medical_claim mc
inner join financial_pmpm.member_months mm on mc.patient_id = mm.patient_id
and
mc.data_source = mm.data_source
and
to_char(mc.claim_start_date, 'YYYYMM') = mm.year_month
group by mc.data_source
, to_char(claim_start_date, 'YYYYMM')
, claim_type
)

PMPM by Chronic Condition

Here we calculate PMPM by chronic condition. Since members can and do have more than one chronic condition, payments and members months are duplicated. This is useful for comparing spend across chronic conditions, but should be used with caution given the duplication across conditions.

WITH chronic_condition_members as 
(
select distinct 
patient_id
from chronic_conditions.tuva_chronic_conditions_long
)

,chronic_conditions as (
select patient_id
, condition_family

UNION 

select p.patient_id
, 'No Chronic Conditions' as condition_family
, 'No Chronic Conditions' as Condition

left join chronic_condition_members ccm on p.patient_id=ccm.patient_id

Claims and Enrollment

Understanding the relationship between enrollment and claims is paramount for in-depth claims and population health analysis. It is important to analyze the proportion of the enrolled population that is actively utilizing healthcare services and to identify the characteristics of those who have not accessed care at all.

Members with Claims by Month

Claims with Enrollment

The inverse of the above. Ideally this number will be 100%, but there could be extenuating reasons why not all claims have a corresponding member with enrollment.

select 
mc.data_source
, sum(case when mm.patient_id is not null then 1 else 0 end) as claims_with_enrollment
, count(*) as claims
, cast(sum(case when mm.patient_id is not null then 1 else 0 end) / count(*) as decimal(18,2)) as percentage_claims_with_enrollment
from core.medical_claim mc
left join financial_pmpm.member_months mm on mc.patient_id = mm.patient_id
and
mc.data_source = mm.data_source
