ADL Dependency Classification and Assessment

Standard Classification Terms

The American Academy of Family Physicians uses the term "ADL-dependent" to identify persons requiring help with basic self-care activities 1
The American Academy of Family Physicians indicates that "Dependent in ADLs" requires assistance from another person to complete one or more basic activities of daily living 1
A person is described as "Moderately frail" (Clinical Frailty Scale level 6) when they need minimal assistance with activities such as dressing and require help with all outside activities and household maintenance 2

The American Academy of Family Physicians distinguishes between different levels of assistance needs, including "Independent", which means the person performs all ADL activities without assistance from another person 1
A person who can perform activities independently but requires someone nearby for safety, verbal cues, or occasional physical assistance is described as needing "Standby assist" 2

Basic ADLs (P-ADLs or personal ADLs) include fundamental self-care activities such as bathing, dressing, toileting, transferring, continence, and feeding, as defined by the American Academy of Family Physicians and Alzheimer's and Dementia research 1, 3
Instrumental ADLs (IADLs) include more complex activities such as shopping, cooking, managing finances, managing medications, using transportation, doing housework, using the telephone, and doing laundry, as defined by the American Academy of Family Physicians, Alzheimer's and Dementia research, and Otolaryngology--head and neck surgery 1, 3, 4

The American Academy of Otolaryngology-Head and Neck Surgery recommends specifying the exact ADL impairments and level of assistance required rather than using vague language like "needs assistance" 5
The American Academy of Family Physicians and Otolaryngology--head and neck surgery recommend using standardized assessment tools such as the Katz Index of Independence in ADLs or the ADL scale to quantify dependency levels 1, 4
The American Academy of Family Physicians recommends documenting whether assistance is needed from another person versus the ability to perform with adaptive equipment alone 1, 6

When ADL dependence is caused by a cerebrovascular accident, assign the appropriate sequelae of stroke code (I69.xxx) as the principal diagnosis and add Z74.1 (Need for assistance with personal care) as a secondary code to capture the functional limitation【7】.

Minimal assistance is defined as the patient providing more than 50 % of the effort required to complete the activity, with the caregiver supplying the remainder【8】.

The basic ADLs that should be documented when coding Z74.1 include bathing, dressing, toileting, transferring, continence, feeding, and grooming【8】.

Z74.2 – “Need for assistance at home and no other household member able to render care” should be used when the patient lacks any capable co‑habitants【8】.
Z74.3 – “Need for continuous supervision” is appropriate when the patient requires constant oversight for safety or task completion【8】.
