The MASD medical abbreviation stands for moisture associated skin damage, which is redness, soreness and breakdown of the skin caused by long contact with urine, stool, sweat, wound fluid or drainage around a stoma. The skin becomes soft and waterlogged, loses its protective outer layer and becomes easy to irritate or erode.
MASD is a term used mostly by nurses and wound care teams. It appears in skin assessments, wound notes and care plans in hospitals, nursing homes and home health. It sits beside other chart shorthand covered on the nursing abbreviations hub, and it is often discussed together with pressure injuries because the two can occur in the same areas.

The four types grouped under MASD
MASD is an umbrella term. Wound care teams commonly sort it into four types, named by the source of the moisture.
| Type | Moisture source | Typical location |
|---|---|---|
| Incontinence associated dermatitis (IAD) | Urine, stool or both | Buttocks, groin, inner thighs, perineum |
| Intertriginous dermatitis (ITD), also called intertrigo | Trapped sweat and friction where skin touches skin | Under breasts, belly folds, armpits, groin |
| Periwound moisture associated dermatitis | Fluid draining from a wound | Skin around the wound edge |
| Peristomal moisture associated dermatitis | Stool or urine leaking under an ostomy pouch | Skin around a stoma |
A note may name the type directly, such as IAD, or use MASD when the exact cause is mixed or not yet sorted out.
How the MASD medical abbreviation shows up in charts
Nursing skin assessment: "MASD to sacrum and buttocks, diffuse erythema, partial thickness erosion, no slough. Barrier cream applied, incontinence pads changed q2h and prn." Erythema means redness, partial thickness means the top layers are damaged, slough is dead yellow tissue, q2h means every two hours and prn means as needed.
A wound care consult might add MASD, IAD type, not a pressure injury, edges diffuse and irregular. That last phrase matters, since describing the shape helps separate the two problems.
MASD or pressure injury?
Both problems often appear on the buttocks and lower back, so telling them apart is a regular skill in nursing. Getting it right shapes the care plan and the record, since pressure injuries are staged and tracked separately.
| Feature | MASD | Pressure injury |
|---|---|---|
| Cause | Moisture and chemical irritation | Pressure or shear over a bony point |
| Shape | Patchy, diffuse, mirror image patterns | Usually a defined round or oval area |
| Depth | Usually shallow | Can be shallow or very deep |
| Location | Skin folds, perineum, around wounds or stomas | Over bone, such as sacrum, heels, hips |
| Dead tissue | Not typical | Can be present in deeper stages |
Some areas show both at once, and a note can record both diagnoses.
General approach to care
Care plans for MASD usually share the same principles. The team looks for the moisture source and reduces it, such as by managing incontinence, adjusting a leaking ostomy appliance or choosing a dressing that holds more wound fluid. Skin is cleaned gently with a pH balanced cleanser rather than harsh soap and rubbing. A skin protectant or barrier product shields the area from further exposure, and fabric that wicks moisture may be placed in skin folds.
If yeast infection develops on top of the damage, which is common in warm folds, a clinician may add a treatment for that. The exact products depend on the facility and the person, so the plan in the chart is the guide.
Questions families often ask
Seeing MASD in a parent's or partner's care notes can raise worries. A few questions help clarify the situation with the care team.
- What is the moisture source, and how is it being managed?
- Is this moisture damage, a pressure injury, or both?
- How often will the skin be checked and cleaned?
- What signs would mean it is getting worse?
The information here describes a nursing term in general. Questions about a particular person's skin or wound plan go to the nurse or wound specialist caring for them.
Frequently asked questions
What does MASD mean in nursing?
MASD means moisture associated skin damage. It describes skin that is red, sore or broken down after long contact with urine, stool, sweat or wound or stoma fluid.
Is MASD a pressure ulcer?
No. MASD comes from moisture, while a pressure injury comes from pressure or shear over bone. The two may resemble each other and often coexist, so nurses chart them separately.
What is IAD and how does it relate to MASD?
IAD stands for incontinence associated dermatitis. It is the type of MASD caused by contact with urine or stool, and it is the most common form in hospitals and nursing homes.
Is MASD staged like a pressure injury?
No. Pressure injury stages do not apply to MASD. Nurses describe the area, depth and cause in words instead.
