ICD 10 Codes for wound care billing

Overview of ICD-10 Codes for Wound Care Billing

International Classification of Diseases codes (ICD-10 codes) is used to classify and report medical diagnoses and procedures in healthcare billing. They are an integral part of the billing process for wound care services, as they provide essential information about the patient’s condition and treatment. There are many ICD-10 codes related to wound care, but here are standard codes used for wound care billing services:

Open Wound ICD-10-CM Coding

Open wound diagnosis codes are classified based on anatomic location on the body, laterality, interaction, and wound type. These codes can also be seen frequently across body areas. Laceration without a foreign body, laceration with a foreign body, puncture wound without a foreign body, puncture wound with a foreign body, open bite, and nonspecific open wound are the several forms of open wounds categorized by ICD-10-CM. Wound care billing services typically include a wide range of treatments, from minor wound cleaning and dressings to more complex procedures such as skin grafts and surgery. Proper coding is essential for accurate reimbursement and to ensure that the patient receives the appropriate level of care. Wound care providers should be familiar with the ICD-10 codes and their meanings to ensure the usage of the correct codes.

As an illustration,

S81.812A Laceration without the presence of a foreign body, right lower thigh, the first encounter

S61.431A Puncture wound on right hand without foreign body, the first encounter

S61.432A Puncture wound on left hand without foreign body, the first encounter

W54.0XXA Dog bit, the first encounter

In ICD-10-CM, injuries in all areas are organized under various category code ranges, such as:

S00–S09 – head

S10–S19 – neck

S20–S29 – thorax

S30–S39 – belly, lower back, lumbar spine, pelvis, and external genitals

S40 to S49 – upper arm and shoulder

S50 to S59 – forearm and elbow

S60 to S69 – wrist and hand

S70-S79 – hip and thigh

S80-S89 – knee and lower leg

S90- S99 – Ankle and foot sizes

T07 refers to numerous unspecified injuries, and T14 refers to an unknown bodily location.

Each category code has more precise codes to help document the wound. The fourth digit indicates whether the wound is simple or complicated and whether tendons are involved.

More particular codes for open wounds of the thigh, for example,

S71.10 – Unspecified open thigh wound

S71.101 – Unspecified open thigh wound

S71.102 – Unspecified open thigh wound

S71.109 – Unspecified open wound, unspecified thigh

S71.11 – Thigh laceration without foreign body

S71.111 – Right thigh laceration without foreign body

S71.112 – Left thigh laceration without foreign body

S71.119 – Laceration of the thigh without the presence of a foreign body

S71.12 – Laceration of the thigh with the foreign body

S71.121 – Laceration of the right thigh

S71.122 – Laceration of the left thigh

S71.129 – Laceration with foreign body, nonspecific thigh

S71.13 – Puncture wound on thigh without foreign body

S71.131 – Puncture wound on right thigh

S71.132 – Puncture wound on left thigh without foreign body

S71.139 – Puncture wound without foreign body, nonspecific thigh

S71.14 – Thigh foreign body puncture wound

S71.141 – Foreign body puncture wound on the right thigh

S71.142 – Foreign body puncture wound on the left thigh

S71.149 – Foreign body puncture wound, unidentified thigh

S71.15 – Thigh open bite

S71.151 – Right thigh, open bite

S71.152 – Left thigh, open bite

S71.159 – Unspecified thigh, open bite

Ulcer VS Wound

Discussions, debates, and articles have been written about the distinction between a “wound” and an “ulcer.” Remember that in ICD-10, a wound refers to something that happens traumatically. All wound codes start with the letter “S.” The term “ulcer” refers to a skin break that does not heal properly and is usually more chronic. While many clinicians use the words “ulcer” and “wound” interchangeably, they are not synonyms for ICD-10 coding.

L97.211 – Non-pressure chronic ulcer of right ankle

L97.212 – Non-pressure chronic ulcer of left ankle

L97.219 – Non-pressure chronic ulcer of unspecified ankle

L89.211 – Pressure ulcer of right heel

L89.212 – Pressure ulcer of left heel

L89.219 – Pressure ulcer of unspecified heel

T81.11XA – Unplanned return to the operating room for wound complication, following skin graft, initial encounter

T81.12XA – Unplanned return to the operating room for wound complication, following skin graft, subsequent encounter

Z48.21 – Encounter for change or removal of wound dressing

It’s important to note that these codes are just a small sample of the many codes available for wound care billing services. The specific code used will depend on the patient’s condition and the type of treatment provided.


ICD-10 codes play a vital role in the billing process for wound care services. Proper coding and documentation are essential for accurate reimbursement and ensuring patients receive appropriate care. Providers should be familiar with the codes and their meanings and ensure that all necessary information is included in the patient’s medical record. With this knowledge and attention to detail, providers can ensure that they are reimbursed correctly for their services.
