The True Cost of In-House OASIS Coding

It's more than salary. Here's the full picture.

Most agency owners know their in-house coder's salary — typically $55,000–$65,000 per year based on AAPC survey data for HCS-D certified coders. But the fully loaded cost, including benefits, training, PTO coverage, management overhead, and the revenue impact of coding errors, can be significantly higher. Here's an illustrative breakdown.

Cost Category In-House
Base salary / per-assessment cost $55,000 - $65,000/yr
Benefits (health, dental, 401k) $12,000 - $18,000/yr
PTO & sick time (+ coverage) $5,000 - $8,000/yr
Training & continuing education $2,000 - $4,000/yr
Management & oversight $5,000 - $10,000/yr
Turnover costs (avg 18-month tenure) $8,000 - $15,000/event
Estimated Annual Total $87,000 - $120,000+

Salary ranges based on AAPC salary survey data for HCS-D certified coders. Benefits estimated at standard 20–30% of base salary. Turnover costs include recruiting, onboarding, and productivity loss during transition. Actual costs vary by location and agency size.

When Does Each Approach Make Sense?

Outsourcing works well when:

  • Volume is under 200 assessments/month (a full-time coder is underutilized)
  • Census fluctuates seasonally
  • Your in-house coder is a single point of failure
  • Your denial rate is above 5%
  • You want to grow without adding headcount

In-house may be better when:

  • Consistent volume over 300+ assessments/month
  • You need the coder on-site for clinical collaboration
  • You have reliable backup coverage during PTO/illness

The Hybrid Approach

Many agencies use HH Coder alongside their in-house staff. Common scenarios include:

Overflow Coverage

Use HH Coder when volume spikes beyond what your in-house team can handle, instead of building permanent staff for peak periods.

PTO & Sick Day Coverage

Keep assessments moving when your coder is out. No backlog when they return.

Quality Assurance

Use our coders as a second set of eyes on complex cases or as a benchmark for your in-house team's accuracy.
