The Hidden Costs of Manual Medical Coding and How AI Saves Money

By Kacie Geretz, RCM Solutions Manager

April 11, 2025

Key Takeaway: Healthcare organizations face growing pressure to improve patient care while cutting costs. Medical coding is one of the best places to start, as the manual process creates hidden financial burdens, including labor expenses, medical coding errors, and compliance penalties. AI medical coding solutions address these challenges while empowering coding staff to focus on complex cases, creating a win-win for organizations and employees alike.

What are the "Hidden Costs" of Manual Coding?

Beyond the standard salary expenses visible in departmental budgets, manual medical coding creates significant hidden costs that impact financial performance. The true cost of medical coding typically exceeds budgeted amounts by 30-40% when these hidden expenses are fully quantified:

Driver

Description

Labor-Intensive Nature

Hidden expenses beyond salaries: recruitment, training, productivity gaps, compliance education, management, and facility costs

Revenue Leakage

Hidden leakage: rework processes, extended collections, administrative follow-up, and uncaptured revenue from abandoned claims

Documentation Inefficiencies

Productivity drains: time searching records, physician queries, delayed submissions, and extended billing cycles

1. Hidden Labor Costs Beyond Base Salaries

While salary expenses appear clearly on financial statements, manual coding operations incur numerous invisible costs through continuous recruitment activities, training requirements, and productivity losses during staff transitions. Additional expenses accumulate through ongoing compliance education, management oversight, and physical workspace needs; costs rarely captured in departmental reporting or standard financial analyses.

  • Example: A mid-sized healthcare system processing 500,000 annual encounters requires approximately 67 coders at an average salary of $70,000, translating to roughly $4.7 million in direct labor costs annually – but the true cost, including these hidden factors, often approaches $6.5 million.

2. Revenue Leakage Through Denials and Rework

Coding and charging inconsistencies create significant financial leakage through denied claims that necessitate resource-intensive investigation, correction, and resubmission processes. These workflow disruptions extend collection timelines and divert staff from revenue-generating activities, while a substantial portion of initially rejected claims never complete the resubmission cycle, resulting in permanent revenue loss. Medical coding errors represent one of the largest contributors to these denied claims, with each error potentially causing delays in reimbursement and requiring additional staff hours to resolve.

  • Example: For an organization processing 5,000 claims monthly with a typical 10% denial rate, this translates to 500 monthly denials and approximately $300,000 annually in rework costs alone, not including permanent revenue loss from claims that are never successfully resubmitted.

3. Productivity Loss From Documentation Challenges

Significant efficiency drains occur as coding staff navigates through extensive clinical documentation, searching for relevant information and managing physician queries for clarification. These non-productive activities consume valuable staff time that could otherwise contribute to throughput improvement while simultaneously extending billing cycles and delaying reimbursement.

How Can AI Reduce Medical Coding Costs?

As healthcare organizations face increasing pressure to reduce costs while operating on thin margins, autonomous medical coding offers practical solutions to address the hidden financial challenges we've identified. By targeting these cost drivers directly, modern coding technology helps coding departments achieve more with existing resources:

1. Optimizing Labor Economics Without Adding Headcount

Autonomous medical coding helps organizations manage growing volumes without proportional increases in staffing costs by handling routine cases automatically. This approach frees experienced coding professionals from repetitive chart work, allowing them to focus on complex cases where their expertise adds the most value. Coding departments can maintain productivity even during volume fluctuations, eliminating the constant pressure to recruit, train, and maintain larger teams to handle routine work.

  • Real-World Example: After implementing Nym's autonomous medical coding engine, Inova Health System eliminated overtime requirements, removed limits on PTO for in-house coders, and stopped using expensive contract coders. This resulted in over $500,000 in annual ED medical coding cost savings and enabled them to promote four ED coders to higher complexity areas. Read the Inova Case Study.

2. Minimizing Revenue Leakage Through Error Reduction

Autonomous solutions apply current coding guidelines consistently across all encounters, addressing a major source of costly denials and rework that strains departmental resources. These systems reduce medical coding errors that trigger rejections, helping coding teams achieve cleaner claims without the exhausting follow-up work that extends collection cycles. With fewer denials to manage, staff can redirect their expertise toward prevention and process improvement rather than constant claim corrections.

  • Real-World Example: Riverland Health saw improved facility charge capture levels with Nym's AI solution, which consistently applied internal coding guidelines and maintained accurate documentation of care levels. This increased the average reimbursement per encounter while identifying medical coder education opportunities to improve manual coding accuracy going forward. Read the Case Study.

3. Accelerating Cash Flow and Streamlining Compliance Costs

If an autonomous coding solution can't assign the appropriate medical codes to a patient encounter with high confidence (and therefore routes the encounter to a medical coder for manual processing), it is typically due to a documentation error, missing information, or complex/uncommon coding types. In the case of the first two reasons, many autonomous coding solutions will "flag" the issue with the patient record and provide the medical codes it had planned on assigning, accelerating claim processing and, therefore, revenue.

An additional benefit unique to Nym's autonomous medical coding engine is the production of audit trails. These audit trails, which are produced for every code Nym's engine assigns, contain supporting documentation, links to guidelines referenced during code selection, and more, providing health information departments with an actionable resource for audits, denials, or compliance initiatives. This impacts revenue cycle metrics by accelerating appeals processes and helping improve future clean claim rates, ultimately protecting and optimizing reimbursement. As healthcare automation continues to evolve, these audit capabilities will become increasingly valuable for maintaining regulatory compliance while reducing manual effort. Learn more about Nym’s autonomous medical coding technology.

FAQ About AI and Medical Coding Costs

Are AI-powered coding systems more expensive to implement than manual coding?

While upfront costs exist, organizations can save money in the long term thanks to decreased labor, fewer mistakes, reduced denials, faster payment cycles, and avoided compliance penalties.

How long does it take to see financial ROI after implementing AI medical coding?

Most organizations begin seeing measurable ROI within 3-6 months through immediate reductions in overtime and decreased reliance on contract coders. Secondary benefits appear within 6-9 months through improved charge capture, reduced denials, and accelerated payment cycles.
