Diagnosis record

A fictional adult has closed fractures of two metatarsal bones in the right foot. The treating clinician confirms both injuries and documents the individual sites. Both are managed without manipulation at this encounter.

Treatment plan

The physician supplies one closed-treatment plan using a single immobilization device for that foot and assumes follow-up. No fracture in this record undergoes manipulation, percutaneous fixation or open treatment. The exercise stipulates that both fractures fall within the cited shared-treatment policy.

Documentation distinction

The chart preserves two fracture diagnoses. A preliminary procedure worksheet duplicates the same closed-treatment-without-manipulation service solely because there are two diagnoses. The learner must apply the procedure-unit rule while retaining the supported injury details.

Lookup scope

Use the current diagnosis and procedure references to complete the site-specific entries. The scored question concerns the Medicare unit relationship, not a rule that all fractures everywhere always form one service. Different anatomy or treatment would require reassessment.

Your coding worksheet

Preserve both documented injuries.
Identify the shared treatment without manipulation.
Apply the stated unit policy.
Explain why diagnosis count and procedure units differ.

In your notebook, record the supported facts, your index route, the instructions you checked, and any missing detail that limits your answer.

Compare with the worked explanation

Two supported fracture diagnoses remain in the abstraction.
One shared immobilization treatment without manipulation is supplied for the stated anatomical area.
The specific NCCI policy does not permit automatically duplicating the treatment unit for each fracture in this relationship.
Diagnosis detail and procedural units answer different questions; use the applicable family and payer rule without deleting an injury or inventing another treatment.
