Most Missed Medical Coding Concepts Ambulatory Surgical with practice questions

Pay attention to Activity Codes

  • Activity codes and place of occurrence codes are used in ICD-10-CM for injuries

  • Activity codes describe the cause of the injury, such as playing tennis

  • Place of occurrence codes describe where the injury occurred, such as a tennis court

  • The 7th character "a" represents initial encounters in injury coding

  • Examples of initial care include emergency department treatment, evaluation and management, and surgical treatment

  • The 7th character "d" is for subsequent encounters, such as cast change or removal, adjustments, and follow-up visits

  • The 7th character "s" is for sequela, which are complications or conditions that arise as a direct result of an injury

Open Burst Fracture

  • Peripheral nerve or blood vessel injuries should be coded separately from the primary injury

  • Fractures should be coded based on site, laterality, and type of fracture

  • Open fractures are classified using the Gustillo classification, with higher numbers indicating worse damage

  • Limb salvage for traumatic fractures uses the appropriate 7th character extender for initial encounter

Principal Diagnosis Code

  • Burn codes are used for thermal burns, burns from electricity or radiation, and corrosions

  • The code for the burn of the highest degree is sequenced first when treating external burns

  • The circumstances of admission govern the selection of the principal diagnosis for burn injuries and related conditions

  • Codes from category T31 are used for burns classified by extent of body surface involved

  • Codes from category T32 are used for corrosions classified by extent of body surface involved

The Adverse Effect

  • Adverse effects occur when a substance is taken correctly but a reaction occurs

  • Adverse effects are coded using the appropriate code for the adverse effect and additional codes for manifestations

  • Saline solution may be instilled to improve visibility during the procedure.

  • Contrast medium is used for radiological study of ureteric and renal pelvic structures.

Supporting details:

  • Ureteral catheterization or ureteral pyelography is done through the stethoscope.

Coding Information

  • Code 52001 includes a diagnostic cystourethroscopy.

  • Code 5200 should not be reported with 52001.

My advice:

- Process of elimination!!

- work on your speed

- Study sequencing

- Fix CPT sequencing issue

- Coding irregularities

- Similarities with possible answer

- Headers before CPT codes
