S72.001A

Fracture of unspecified part of neck of right femur, initial encounter for closed fracture

S72.001A is a clinical classification for a fracture occurring in the neck of the right femur, where the precise anatomical sub-location (such as subcapital, transcervical, or basicervical) is not specified. The 'A' extension identifies this as the initial encounter for a closed fracture, meaning the patient is currently receiving active treatment, which may include emergency surgical stabilization, traction, or internal fixation. This condition is a major orthopedic emergency, particularly in geriatric populations where it is frequently associated with osteoporosis, but it also occurs in younger patients following high-energy impact. The neck of the femur is an intracapsular region, and fractures here carry a significant risk of disrupting the blood supply to the femoral head, potentially leading to avascular necrosis. Immediate clinical management is essential to reduce the risk of secondary complications like deep vein thrombosis, pneumonia, and permanent mobility loss.

Clinical Symptoms

Acute, severe pain in the right hip or groin area
Total inability to bear weight on the right lower extremity
Shortening of the right leg due to muscular contraction pulling the distal fragment
Noticeable external rotation of the right foot and leg
Visible swelling and ecchymosis (bruising) over the lateral hip
Pain that worsens with any passive or active movement of the joint
Tenderness upon palpation of the greater trochanteric region

Common Causes

Falls from standing height in individuals with reduced bone mineral density
High-energy mechanical trauma such as motor vehicle accidents or falls from heights
Primary or secondary osteoporosis causing bone fragility
Repetitive stress or overuse in high-impact athletes (stress fractures)
Pathological bone weakening from metastatic cancer or Paget's disease
Nutritional deficiencies specifically in Calcium and Vitamin D
Long-term use of medications that affect bone metabolism, such as glucocorticoids

Documentation & Coding Tips

Specify the exact anatomical location within the femoral neck to avoid unspecified codes.

Example: Patient presents with a closed, displaced transcervical fracture of the right femoral neck following a mechanical fall from standing height. Examination shows external rotation and shortening of the right lower extremity. History of senile osteoporosis (M81.0) noted. Billing Focus: Right laterality and transcervical site specificity. Risk Adjustment: Captures HCC for hip fracture and identifies underlying osteoporosis as a contributing factor.

Billing Focus: Laterality and anatomical sub-site (e.g., transcervical, basicervical, subcapital).

Clearly document the displacement status of the fracture as it significantly impacts surgical planning and coding.

Example: Radiographs confirm a non-displaced fracture of the right femoral neck, unspecified portion. Patient is a 78-year-old with chronic kidney disease stage 3 (N18.30). Billing Focus: Displacement status (non-displaced). Risk Adjustment: Chronic kidney disease adds complexity to surgical recovery and metabolic bone health.

Billing Focus: Displaced vs. non-displaced status.

Always indicate the encounter phase using the 7th character A, D, or S to ensure accurate claim processing.

Example: Initial encounter for a closed fracture of the neck of the right femur. Patient was brought to the ED immediately following a fall at a skilled nursing facility. Billing Focus: 7th character A for initial encounter. Risk Adjustment: Distinguishes acute injury phase from recovery, affecting resource allocation calculations.

Billing Focus: Episode of care (Initial, Subsequent, or Sequela).

Incorporate the mechanism of injury and the environment where it occurred to provide context for external cause codes.

Example: Initial encounter for right femoral neck fracture resulting from a slip and fall on ice in a residential driveway (W00.0XXA). Patient has a history of tobacco use (Z72.0). Billing Focus: External cause linkage. Risk Adjustment: Social determinants of health and lifestyle factors like tobacco use impact healing times.

Billing Focus: Linkage to external cause codes (W-series).

Document all co-existing chronic conditions that may affect the management of the acute hip fracture.

Example: A 82-year-old female with an initial encounter for a closed right femoral neck fracture. Assessment includes stable heart failure (I50.9) and type 2 diabetes (E11.9). Billing Focus: Secondary diagnoses for systemic illness. Risk Adjustment: Multiple chronic conditions increase the HCC weight and expected length of stay.

Billing Focus: Comorbidities like CHF, Diabetes, or Dementia.

Relevant CPT Codes

27230 - Closed treatment of femoral neck fracture; without manipulation
Applied when the fracture is stable and requires only observation and activity restriction.
27235 - Percutaneous skeletal fixation of femoral neck fracture
Common surgical intervention for non-displaced or minimally displaced femoral neck fractures.
27236 - Open treatment of femoral neck fracture, internal fixation, or prosthetic replacement
Standard of care for displaced femoral neck fractures (Hemiarthroplasty or ORIF).
99213 - Office or other outpatient visit for the evaluation and management of an established patient, which requires a low level of medical decision making
Used for routine post-operative checks where complications are minimal and decision making is straightforward.
