What Are Local Coverage Determinations (LCDs)?

First things first—what exactly are Local Coverage Determinations (LCDs)?

In a nutshell, LCDs give individual Medicare jurisdictions (run by Medicare Administrative Contractors or MACs) the freedom to decide if a specific service or item will be covered. Think of it as Medicare outsourcing decisions to regional administrators to better tailor coverage based on local medical practices and needs.

For example, a MAC can establish what’s covered, how services must be coded, and even how they must be billed to meet Medicare requirements. Sounds simple, right? But here’s the kicker: If your claim doesn’t meet LCD guidelines, it will get denied faster than you can hit “submit.”

How Most People Learn About LCDs (Spoiler: It’s Not Fun)

If you’re not knee-deep in billing and coding, chances are you first learn about LCDs when your claim is denied.

Picture this: You submit a claim to Medicare, expecting smooth processing. Instead, it comes back rejected with a note saying, “Does not meet LCD guidelines.” Yikes. That’s when most people start scrambling to determine these rules, where to find them, and how to follow them.

The good news is you don’t have to wait for a rejection to figure this out. Everything you need is conveniently located on the CMS.gov website—and that’s exactly where we’re headed next.

Navigating the CMS.gov Website for LCDs

So, how do you even begin with LCDs? Start with the CMS.gov Local Coverage Determinations page. This is the go-to resource for understanding LCDs, finding jurisdiction-specific guidelines, and avoiding those dreaded claim rejections.

Here’s what you’ll find on the CMS page:

An Overview of LCDs: This is perfect if you’re new. It explains what LCDs are and why they matter.
FAQs and Integrity Manual: These are great for common questions and detailed policy explanations.
State-Specific Jurisdictions and MACs: This is where things get interesting. Every state has a specific MAC (Medicare Administrative Contractor) responsible for handling claims.

Finding Your MAC and LCDs

Let’s break this down with an example:

If you’re in Oregon, your Medicare Parts A and B MAC are Noridian Healthcare. Oregon falls under Jurisdiction F, and Noridian manages everything related to claims for this area.

The CMS page includes a handy list of MACs by state. Each includes a link to the MAC’s website, where you can access active LCDs, updates, and helpful tools.

For instance, once you’re on Noridian’s site, you’ll find:

Active LCDs: These are the policies currently in place.
Billing and Coding Articles: Helpful guides to ensure your claims meet all LCD requirements.
Medicare Portal Access: You can check claim statuses, verify beneficiaries, and more.
Fee Schedules, Forms, and Education Resources: Everything from ABNs to CMS 1500 forms.

Let’s dig deeper into active LCDs because this is where the real magic happens.

Active LCDs: Your Blueprint for Billing Success

Once you navigate the active LCDs section, you’ll find a policy list that outlines what’s required for various services. These policies vary by state and jurisdiction, so it’s crucial to determine the specific ones relevant to you.

Here’s what you’ll see:

Title: A service description (e.g., “Benign Skin Lesion Removal”).
LCD Number: Each policy is assigned a unique identifier.
Billing and Coding Articles: These explain how to submit claims properly.
CPT/HCPCS Codes: Lists the covered procedure codes.

Let’s say you’re an orthopedist. You’d scroll through to find policies like Total Hip Arthroplasty, Total Knee Arthroplasty, or Trigger Point Injections. Each one outlines the exact criteria you need to meet for coverage.

A Quick Look at Trigger Point Injection LCD

Take the LCD for Trigger Point Injections, for example. Here’s what you’d find:

Coverage Guidance: Explains what conditions must be present to justify the procedure.
Medical Necessity Criteria: Break down major and minor criteria that must be documented.
Billing Requirements: This section details the covered CPT codes and the exact ICD-10 diagnosis codes that must accompany them.

For instance, if you’re billing CPT code 20552, it will only be covered if paired with specific ICD-10 diagnosis codes. These must be documented accurately to ensure the claim isn’t denied.

Pro Tip: Bookmark your MAC’s LCD page so you can regularly check for updates—these policies change frequently!

Understanding Local Coverage Determinations is a game-changer for anyone billing Medicare. From finding your MAC to using active LCDs as your blueprint, this is the foundation for submitting clean claims that get approved the first time.

Why LCDs Matter for Every Specialty

Local Coverage Determination isn’t a one-size-fits-all solution. They are tailored to specialties, meaning what applies to a dermatologist won’t necessarily apply to an orthopedist, podiatrist, or internist.

Let’s break it down by specialty:

Orthopedics

If you’re in orthopedics, some of the most common LCDs you’ll encounter might include:

Total Hip Arthroplasty
Total Knee Arthroplasty
Trigger Point Injections

For procedures like these, LCDs often specify detailed medical necessity criteria. For instance, you’re billing for total knee replacement surgery. The LCD might require:

Documented failure of non-surgical treatments (e.g., physical therapy, medications).
Evidence of advanced joint damage via imaging.
Specific CPT codes paired with ICD-10 codes that confirm the patient’s condition.

If you miss any of these details, your claim could be denied. That’s why it’s essential to review active LCDs on your MAC’s website regularly.

Podiatry

Podiatry is notoriously complicated when it comes to LCDs. Why? Because it often involves a combination of:

CPT Codes: Covering everything from debridement to diabetic foot care.
ICD-10 Codes: For conditions like ulcers, infections, and neuropathy.
Modifiers: To indicate bilateral procedures or distinct procedural services.

For example, an LCD might specify that routine foot care is only covered if it’s directly related to diabetes or peripheral vascular disease. If your claim doesn’t link the procedure to a covered diagnosis, it’ll be rejected.

Another tricky area is wound care. Many LCDs require detailed documentation of treatment progression over time. If your notes aren’t thorough enough, you could lose reimbursement.

Radiology and Imaging

If you’re ordering MRIs, CT scans, or X-rays, LCDs are critical for determining whether these services are medically necessary.

For instance, an LCD for chest X-rays might state:

The procedure is only covered if the patient presents with specific symptoms, such as shortness of breath or suspected pneumonia.
Specific ICD-10 codes must accompany the request.

And remember—what’s considered “necessary” in one jurisdiction might not apply in another. This is where LCDs can feel a little bit like playing a game of Medicare bingo.

Staying Ahead of Changing LCDs

One of the biggest frustrations with Local Coverage Determinations is that they’re not set in stone. Policies frequently change as new medical guidelines, treatments, and technologies emerge.

Here’s how to stay ahead:

1. Bookmark Your MAC’s Website

Make it a habit to check the active LCDs page for updates regularly. Even better—subscribe to their email updates (if available) to get notifications about policy changes.

For example, if you’re in Oregon and use Noridian Healthcare, you’ll want to check their Jurisdiction F LCD page monthly.

2. Assign a Billing Guru

If you’re a provider, don’t try to tackle this solo. Assign someone on your team—whether your billing specialist or practice manager—to monitor LCD updates.

Have them:

Review active LCDs monthly.
Share updates during team meetings.
Flag changes that impact high-volume procedures.

3. Use the CMS Updates Tool

CMS provides regular updates to LCDs through its Medicare Coverage Database. This tool allows you to search for LCDs by:

Keyword
CPT/HCPCS code
Jurisdiction

Make it part of your workflow to search for new updates before submitting high-volume claims.

4. Train Your Team

Your front office staff, coders, and providers all play a role in ensuring compliance with LCDs. If your team isn’t aware of changes, they might submit outdated codes or miss critical documentation requirements.

A quick 10-minute LCD overview during monthly staff meetings can go a long way.

Common LCD Pitfalls (and How to Avoid Them)

Now, let’s talk about the mistakes people make when dealing with LCDs—and how you can sidestep them.

Pitfall 1: Submitting Incomplete Documentation

LCDs often require specific documentation to prove medical necessity. If you’re missing even one key element, your claim is toast.

Solution:
Before submitting a claim, double-check the LCD policy to ensure you’ve included:

The required CPT/HCPCS codes.
A diagnosis code that aligns with the procedure.
Proof of medical necessity (e.g., progress notes, imaging reports).

Pitfall 2: Using Outdated CPT or ICD-10 Codes

Codes change constantly. If your MAC has updated an LCD to reflect new codes and you’re still using the old ones, expect a denial.

Solution:
Keep your billing software and coding manuals up to date. Many MACs also provide downloadable PDF guides for LCD-specific codes—use them.

Pitfall 3: Assuming All MACs Are the Same

Each MAC has its own set of LCDs. Just because something is covered in one jurisdiction doesn’t mean it’s covered in another.

Solution:
Always refer to your specific MAC’s website for guidance. Don’t assume policies are universal.

Pitfall 4: Ignoring LCD Updates

As mentioned earlier, LCDs change frequently. If you don’t check for updates, you’re operating with blinders.

Solution:
Dedicate monthly time to review active LCDs and share updates with your team.

Real-World LCD Case Studies

Sometimes, seeing examples of LCD issues can help you understand where things go wrong—and how to prevent it. Let’s dive into two common scenarios.

Case Study 1: The Trigger Point Injection Denial

Scenario:
A pain management clinic submits claims for multiple Trigger Point Injections using CPT code 20553 (injection of three or more muscles).

Denial:
Medicare denies the claim, stating it “does not meet LCD medical necessity guidelines.”

What Went Wrong:
The LCD for Trigger Point Injections requires documentation of specific medical necessity criteria, such as:

Clear evidence of myofascial pain syndrome.
Failed conservative treatment over a defined period.
Diagnosis codes (ICD-10) are tied directly to the procedure.

The provider included the CPT code but failed to pair it with an appropriate ICD-10 diagnosis code from the approved list. Additionally, the documentation didn’t prove the failure of prior treatments.

Solution:
To fix this:

Review the LCD policy for Trigger Point Injections on the MAC’s website.
Identify the correct ICD-10 codes that align with CPT code 20553.
Ensure that documentation includes:
- The patient’s history of failed conservative treatments.
- The clinical diagnosis that justifies the procedure.

The clinic received reimbursement after correcting and resubmitting the claim with the proper ICD-10 code.

Case Study 2: The Radiology Misstep

Scenario:
A family practice physician orders a chest X-ray for a patient with fatigue and a mild cough. The claim is submitted using CPT code 71046 for a two-view chest X-ray.

Denial:
The MAC rejects the claim, citing a lack of medical necessity per the LCD for chest X-rays.

What Went Wrong:
The LCD for chest X-rays specifies that the procedure is only covered for conditions like:

Shortness of breath.
Suspected pneumonia.
Abnormal findings on physical examination (e.g., crackles).

The submitted ICD-10 code for “fatigue” (R53.83) wasn’t sufficient to justify the procedure under the LCD.

Solution:
To avoid this:

Reference the LCD policy for chest X-rays before ordering the procedure.
Ensure the ICD-10 code aligns with symptoms or diagnoses the policy lists as medically necessary.
Educate providers on LCD criteria for standard procedures they order so the correct codes are used.

Resubmitting the claim with an updated ICD-10 code tied to an appropriate symptom (e.g., cough with abnormal lung findings) led to approval.

How to Appeal Denied Claims

Denied claims are frustrating, but they’re not the end of the road. You can appeal if your claim was rejected for not meeting Local Coverage Determinations.

Steps to Appeal an LCD Denial

Check the Denial Code:
When Medicare denies a claim, it provides a reason for denial or code. Look for language referencing “LCD guidelines.”
Review the LCD Policy:
Go to your MAC’s website and pull up the LCD for the denied procedure. Pay special attention to:
- CPT/HCPCS codes.
- Required ICD-10 codes.
- Documentation or medical necessity requirements.
Gather Documentation:
Ensure you have all the required supporting documents. This might include:
- Progress notes.
- Diagnostic reports.
- Evidence of prior treatments.
Submit a Reconsideration Request:
Use the appeals process outlined by your MAC. Include:
- A corrected claim with proper coding.
- A letter explaining why the claim meets the LCD requirements.
- Supporting documentation.
Follow Up:
Medicare appeals take time, so don’t be afraid to check the status of your claim regularly.
