AR-DRG V9 Severity Indicators (DCL)

Severity indicators are based on the Diagnosis Complexity Level (DCL) from AR-DRG V9 specifications. DCL values (0-5) indicate how much a diagnosis contributes to the Episode Clinical Complexity Score (ECCS), which influences DRG assignment and hospital reimbursement.

Extreme DCL 5

Catastrophic complexity

Maximum DRG weight contribution. Rare, severe multi-system conditions.
Critical DCL 4

Severe complexity (MCC+)

Example: - Sepsis, unspecified
High DCL 3

Major complexity (MCC)

Example: - Pneumonia, unspecified
Moderate DCL 2

Moderate complexity (CC+)

Example: - Type 2 diabetes
Low DCL 1

Minor complexity (CC)

Example: - Essential hypertension
None DCL 0

No complexity contribution

Example: - General examination

ECCS (Episode Clinical Complexity Score)

The ECCS is calculated from all secondary diagnoses using the formula:

ECCS = DCL1 + DCL2×0.84 + DCL3×0.71 + DCL4×0.59 + ...

Each subsequent diagnosis contributes less due to the 0.84 decay factor. Higher ECCS values indicate greater episode complexity.

Data Sources

AR-DRG V9 Official DCL matrix from AR-DRG V9 specifications (high confidence)
Keyword-Based Estimated from diagnosis title keywords (fallback, lower confidence)

How to Use Severity Indicators

  1. Look for the colored severity badge and label next to diagnosis codes in search results
  2. The right-side colored strip on each card provides at-a-glance severity indication
  3. Click on a code to see detailed DCL information in the notes panel
  4. Use the ECCS Calculator button to calculate episode complexity for multiple diagnoses
  5. Prioritize documentation queries for Critical and High severity codes

Understanding Procedure Categories

ACHI procedure codes are categorized by type to help coders quickly identify the nature of interventions and their impact on DRG assignment and resource utilization.

Surgical OR Procedure

Operating room procedures with surgical intervention

Keywords: excision, repair, graft, bypass, amputation
Examples:
• 38653-00 - Coronary artery bypass
• 30571-00 - Appendicectomy
• 35500-00 - Inguinal hernia repair
Medical

Non-surgical therapeutic procedures

Keywords: administration, infusion, transfusion, chemotherapy
Examples:
• 13706-01 - Packed cells transfusion
• 96199-00 - Pharmacological agent admin
• 13839-00 - Blood product infusion
Diagnostic

Imaging, pathology, and diagnostic procedures

Keywords: biopsy, endoscopy, imaging, CT scan, examination
Examples:
• 57001-00 - CT scan of brain
• 30075-00 - Breast biopsy
• 30473-00 - Panendoscopy
Allied Health

Therapy, counselling, and rehabilitation services

Keywords: physiotherapy, occupational therapy, counselling
Examples:
• 95550-00 - Physiotherapy intervention
• 95550-01 - Occupational therapy
• 96067-00 - Nutrition counselling

Operating Room (OR) Flag

Procedures marked with the OR Procedure badge indicate interventions that typically require operating room resources. This is important for:

  • DRG surgical vs medical partition assignment
  • Resource utilization tracking
  • Theatre scheduling and costing

Clinical Documentation Improvement (CDI) Prompts

CDI prompts are intelligent suggestions that help coders identify opportunities for documentation clarification and code specificity improvements.

Unspecified Type Query

Triggered for diagnosis codes ending in .9 (unspecified)

Prompt:
"Query physician for specific type of [condition]"
Example:
Code: E11.9 (Type 2 diabetes mellitus without complications)
→ Query for specific manifestations: nephropathy, retinopathy, neuropathy

Laterality Query

Triggered when laterality is not specified for applicable codes

Prompt:
"Query for laterality (left/right/bilateral)"
Example:
Code: H40.9 (Glaucoma, unspecified)
→ Query: Which eye is affected - left, right, or both?

Organism Query

Triggered for infection codes (Chapter I) without specific organism

Prompt:
"Query for causative organism if identified"
Example:
Code: J15.9 (Bacterial pneumonia, unspecified)
→ Query: Culture results? Streptococcus, Staphylococcus, E. coli?

Complication Query

Triggered for critical severity codes to capture CC/MCC

Prompt:
"Were there any complications or comorbidities?"
Example:
Code: A41.9 (Sepsis, unspecified)
→ Query: Organ dysfunction? Septic shock? Acute kidney injury?

Tenant Customization

Administrators can customize CDI prompts for your organization through the Admin Dashboard. Custom prompts can be tailored to your facility's specific documentation requirements and coding guidelines.

Search Tips & Techniques

Master these search techniques to find codes quickly and accurately.

Basic Search

diabetes → Searches all diabetes-related codes and terms
heart failure → Searches for both words (AND search)

Wildcard Search

diab* → Matches diabetes, diabetic, diabetics, etc.
pneumon* → Matches pneumonia, pneumonitis, pneumonic

Code Search

E11.9 → Direct ICD-10-AM code lookup
30075-00 → Direct ACHI procedure code lookup
0001 → ACS standard number lookup

ICD10AM Lead Terms Search

Select "ICD10AM Lead Terms" category, then search:

abdomen → Find all terms starting with "Abdomen"
diabetes → Find diabetes-related lead terms with codes
R10 → Find lead terms associated with code R10

Anaesthesia Alert System

The Anaesthesia Alert System helps ensure anaesthesia codes are not overlooked when coding surgical procedures, following ACS 0031 guidelines.

How It Works

Procedure-Based Alerts (ACHI Codes):

When you view an ACHI surgical procedure code, the system automatically:

  • Detects if it's a procedure that typically requires anaesthesia
  • Shows an alert panel with suggested anaesthesia codes
  • Allows you to select the ASA Physical Status
  • Lets you add codes directly to your session

Diagnosis-Based Alerts (ICD-10-AM Codes)

When viewing certain ICD-10-AM diagnosis codes, the system proactively reminds you that anaesthesia may be required:

  • Fractures (S02-S92) - May require surgical fixation
  • Appendicitis (K35-K37) - Typically requires appendectomy
  • Gallbladder (K80-K82) - May require cholecystectomy
  • Hernias (K40-K46) - Often require surgical repair
  • Intestinal obstruction (K56) - May need emergency surgery
  • Joint disorders (M16, M17, M23) - May require arthroplasty
  • Malignant neoplasms (C codes) - May need surgical excision
  • Cataracts (H25-H26) - Require cataract extraction

Note: These are reminders, not all diagnoses require surgery.

Anaesthesia Code Categories

92514 General Anaesthesia Block [1910]
92515 Sedation Block [1910]
92508-09 Neuraxial (Spinal/Epidural) Block [1909]
92510-12 Regional Nerve Blocks Block [1909]
92513 Local Infiltration Block [1909]

ASA Physical Status Classification

The two-digit suffix indicates patient risk level:

-10 ASA 1: Normal healthy
-20 ASA 2: Mild systemic disease
-30 ASA 3: Severe systemic disease
-40 ASA 4: Life-threatening
-50 ASA 5: Moribund
-99 ASA: Not stated

ACS 0031 Key Rules

• One code per block per visit: Only ONE code from Block [1910] and/or ONE from Block [1909] per theatre visit
• Exception: 92513 (local infiltration) can be coded alongside other [1909] codes
• Do NOT code: Oral sedation, topical anaesthesia for minor procedures

Using the Alert Panel

Click suggestion → Add code to your session with selected ASA status
Not Required → Dismiss if anaesthesia not applicable (e.g., procedure under local by surgeon)
Done → Confirm and close after adding codes

About ECCS

The Episode Clinical Complexity Score (ECCS) measures cumulative complexity of all diagnoses in an episode. The formula applies a decay factor of 0.84 to successive diagnoses:

ECCS = DCL1 + (DCL2 * 0.84) + (DCL3 * 0.71) + (DCL4 * 0.59) + ...
