HCPCS Level II coding for durable medical equipment, supplies, drugs, and non-physician services.
Where HCPCS Level II Coding Applies
HCPCS Level II covers what CPT does not: supplies, drugs, equipment and certain services. These items carry their own documentation requirements and modifier conventions, and are reviewed closely because they fall outside routine procedure coding.
- Supplies, drugs and equipment coded to the correct HCPCS item
- Units and administration details documented to support the claim
- Modifiers applied per the conventions each category requires
- Coverage policy checked before items are billed
HCPCS Coding Services Explained
HCPCS (Healthcare Common Procedure Coding System) Level II codes are alphanumeric codes used to describe services, supplies, and equipment not captured by CPT codes. They are particularly important for Medicare and Medicaid claims covering durable medical equipment (DME), prosthetics, orthotics, supplies, drugs administered by a provider, and ambulance services. Correct HCPCS Level II coding is required for Medicare reimbursement and most Medicaid programs. CMS updates HCPCS codes quarterly.
Medsure RCS applies HCPCS codes accurately for all applicable service categories, following CMS annual HCPCS code updates, pricing schedules, and coverage policies. Incorrect or missing HCPCS codes are a common source of Medicare and Medicaid denials that are easily prevented with properly trained coding staff. Providers submitting HCPCS claims should also ensure medical coding compliance protocols cover DME-specific billing rules. HCPCS codes are especially critical for Medicare billing and apply throughout medical billing workflows wherever DME and drug administration are billed.

How It Works: Step by Step
Service and Supply Identification
We review clinical documentation and supply records to identify all services and items that require HCPCS Level II coding.
Code Selection and Modifier Application
The correct HCPCS code is selected based on the specific item description, supply type, or drug, with applicable modifiers for coverage qualification.
Coverage Policy Verification
HCPCS codes are verified against applicable Medicare LCDs, DME contractor policies, and Medicaid coverage rules before submission.
Claim Integration
HCPCS codes are integrated into the claim alongside CPT codes and ICD-10-CM diagnosis codes with correct placement per claim form requirements.
The Impact of Accurate Coding
HCPCS Level II codes are updated quarterly by CMS and we implement all updates to prevent rejected claims.
All DME HCPCS codes are checked against applicable DMEPOS coverage policies before submission.
Provider-administered drug and biologic codes are captured separately, not missed as part of the office visit.
HCPCS coding is validated for both Medicare and Florida Medicaid requirements separately.
Common Mistakes in HCPCS Coding Services
Missing HCPCS Codes for Provider-Administered Drugs
When a provider administers a drug or biologic, the drug itself requires a separate HCPCS J-code in addition to the injection or infusion administration CPT code. Missing the J-code means billing only for the administration and not for the drug, which may represent significant revenue.
Using Outdated DME HCPCS Codes
CMS updates the HCPCS Level II code set quarterly, with significant annual revisions. DME suppliers and providers who do not implement updates promptly submit claims with deleted or invalid codes that are rejected at the clearinghouse.
Not Checking DME LCD Coverage Requirements
Medicare DME items are covered only when specific diagnosis codes (ICD-10-CM) are present on the claim that meet the LCD requirements for that item. Submitting a valid HCPCS code without the correct supporting diagnosis codes results in medical necessity denial.
Incorrect HCPCS Modifiers for Competitive Bid or Special Coverage Programs
Medicare and Medicaid HCPCS codes often require specific modifiers to indicate coverage qualifiers, geographic regions, or competitive bidding program eligibility. Missing required modifiers result in claim denials that are not always self-explanatory.
