S73.11 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of iliofemoral ligament sprain of hip. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Iliofemoral ligament sprain of hip

Non-specific codes like S73.11 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for iliofemoral ligament sprain of hip:

  • S73.111 for Iliofemoral ligament sprain of right hip - NON-BILLABLE CODE

  • Use S73.111A for initial encounter - BILLABLE CODE

  • Use S73.111D for subsequent encounter - BILLABLE CODE

  • Use S73.111S for sequela - BILLABLE CODE

  • S73.112 for Iliofemoral ligament sprain of left hip - NON-BILLABLE CODE

  • Use S73.112A for initial encounter - BILLABLE CODE

  • Use S73.112D for subsequent encounter - BILLABLE CODE

  • Use S73.112S for sequela - BILLABLE CODE

  • S73.119 for Iliofemoral ligament sprain of unspecified hip - NON-BILLABLE CODE

  • Use S73.119A for initial encounter - BILLABLE CODE

  • Use S73.119D for subsequent encounter - BILLABLE CODE

  • Use S73.119S for sequela - BILLABLE CODE

Coding Guidelines

The appropriate 7th character is to be added to each code from block Dislocation and sprain of joint and ligaments of hip (S73). Use the following options for the aplicable episode of care:

  • A - initial encounter
  • D - subsequent encounter
  • S - sequela

Patient Education


Hip Injuries and Disorders

Your hip is the joint where your femur (thigh bone) meets your pelvis (hip bone). There are two main parts: a ball at the end of the femur, which fits in a socket in the pelvis. Your hip is known as a ball-and-socket joint. This is because you have a ball at the end of your femur, and it fits into a socket in your pelvis. This makes your hips very stable and allows for a wide range of motion. When they are healthy, it takes great force to hurt them. However, playing sports, running, overuse, or falling can sometimes lead to hip injuries such as:

  • Strains
  • Bursitis
  • Dislocations
  • Fractures (broken bones)

Certain diseases also lead to hip injuries or problems. Osteoarthritis can cause pain and limited motion. Osteoporosis of the hip causes weak bones that break easily. Both of these are common in older people.

Another problem is hip dysplasia, where the ball at the end of the femur is loose in the hip socket. It can cause hip dislocation. Babies who have hip dysplasia are usually born with it, but sometimes they develop it later.

Treatment for hip disorders may include rest, medicines, physical therapy, or surgery, including hip replacement.

Sprains and Strains

A sprain is a stretched or torn ligament. Ligaments are tissues that connect bones at a joint. Falling, twisting, or getting hit can all cause a sprain. Ankle and wrist sprains are common. Symptoms include pain, swelling, bruising, and being unable to move your joint. You might feel a pop or tear when the injury happens.

A strain is a stretched or torn muscle or tendon. Tendons are tissues that connect muscle to bone. Twisting or pulling these tissues can cause a strain. Strains can happen suddenly or develop over time. Back and hamstring muscle strains are common. Many people get strains playing sports. Symptoms include pain, muscle spasms, swelling, and trouble moving the muscle.

At first, treatment of both sprains and strains usually involves resting the injured area, icing it, wearing a bandage or device that compresses the area, and medicines. Later treatment might include exercise and physical therapy.
