Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Wheelchair confinement status

Code First

Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

  • muscular dystrophy G71.0

Information for Patients


Mobility Aids

Mobility aids help you walk or move from place to place if you are disabled or have an injury. They include

  • Crutches
  • Canes
  • Walkers
  • Wheelchairs
  • Motorized scooters

You may need a walker or cane if you are at risk of falling. If you need to keep your body weight off your foot, ankle or knee, you may need crutches. You may need a wheelchair or a scooter if an injury or disease has left you unable to walk.

Choosing these devices takes time and research. You should be fitted for crutches, canes and walkers. If they fit, these devices give you support, but if they don't fit, they can be uncomfortable and unsafe.
