For this edition of the I-10 Corner, we have included some helpful hints that will make coding procedures in the Endocrine System a little easier.   To gain familiarity, practice looking up procedures in the ICD-10-PCS coding book that are performed at your facility on a routine basis.

Knowing the Root Operations is the key to making all of this work!                                              

FROM THE ICD-10-PCS REFERENCE MANUAL

Examples of Root Operations

Excision—Root operation B

Definition: Cutting out or off, without replacement, a portion of a body part

Explanation: The qualifier Diagnostic is used to identify excision procedures that are biopsies

Examples: Partial thyroidectomy, ovarian biopsy

Excision is coded when a portion of a body part is cut out or off using a sharp instrument. All root operations that employ cutting to accomplish the objective allow the use of any sharp instrument, including but not limited to

• Scalpel
• Wire
• Scissors
• Bone saw
• Electrocautery tip

Resection—Root operation T

Definition: Cutting out or off, without replacement, all of a body part

Explanation: N/A

Examples: Total nephrectomy, total lobectomy of lung

Resection is similar to Excision, except Resection includes all of a body part, or any subdivision of a body part that has its own body part value in ICD-10-PCS, while Excision includes only a portion of a body part.

Release—Root operation N

Definition: Freeing a body part from an abnormal physical constraint by cutting or by use of force

Explanation: Some of the restraining tissue may be taken out but none of the body part is taken out

Examples: Adhesiolysis of right ovary

The objective of procedures represented in the root operation Release is to free a body part from abnormal constraint. Release procedures are coded to the body part being freed. The procedure can be performed on the area around a body part, on the attachments to a body part, or between subdivisions of a body part that are causing the abnormal constraint.

Reposition—Root operation S

Definition: Moving to its normal location or other suitable location all or a portion of a body part

Explanation: The body part is moved to a new location from an abnormal location, or from a normal location where it is not functioning correctly. The body part may or may not be cut out or off to be moved to the new location

Examples: Reposition of undescended testicle

Reposition represents procedures for moving a body part to a new location. The range of Reposition procedures includes moving a body part to its normal location, or moving a body part to a new location to enhance its ability to function.

Laterality is necessary in code assignment for the following organs:

• Thyroid
• Ovaries
• Testicles
• Adrenals

Don’t Forget: 0 vs O:

FROM THE ICD-10-PCS REFERENCE MANUAL

Values

One of 34 possible values can be assigned to each character in a code: the numbers 0 through 9 and the [whole] alphabet (except I and O, because they are easily confused with the numbers 1 and 0).

FROM THE ICD-10-CM OFFICIAL GUIDELINES FOR CODING AND REPORTING 2014
B4. Body Part

B4.3 Bilateral body part values are available for a limited number of body parts. If the identical procedure is performed on contralateral body parts, and a bilateral body part value exists for that body part, a single procedure is coded using the bilateral body part value. If no bilateral body part value exists, each procedure is coded separately using the appropriate body part value.
