OPCS - Coding standards Flashcards
PCSA3: Neurostimulators (A09, A33, A48 and A70)
When a neurostimulator is permanently implanted under the skin:
• Code classifying the implantation of neurostimulator
• Chapter Z site code, where this adds more information
• Z94.- (if applicable)
When electrode leads are implanted temporarily to test effectiveness, and the generator is not implanted:
• Code classifying the implantation of electrodes
• Y70.5 temporary operations
• Chapter Z site code, where this adds more information
• Z94.- (if applicable)
What do you need to remember when coding ECT?
• For the first administration within a course of therapy assign code A83.8
Other specified electroconvulsive therapy in the primary position
• Where a number of courses have been administered during the same consultant episode, all instances of A83.8 must be assigned before assigning A83.9
• For subsequent administrations in the same course of therapy (whether in the same consultant episode within a hospital provider spell or a subsequent hospital provider spell) code A83.9 Unspecified electroconvulsive therapy must be assigned.
PCSD3: Combined approach tympanoplasty (D14.4)
A code for the graft material used must not be assigned in addition to code D14.4
Combined approach tympanoplasty as the graft is implicit within the code.
PCSE1: Laryngopharyngectomy (E19 and E29)
When coding laryngopharyngectomy the following codes and sequencing must be used:
E19.- Pharyngectomy
E29.- Excision of larynx
The fourth character codes assigned will be dependent upon whether the excisions are
total, partial or unspecified.
PCSE4: Non operations on lower respiratory tract (E85–E98) and ventilation support (E85)
Codes in categories E85–E98 must only be used for outpatient coding, or if the patient is admitted solely for the purpose of a procedure/intervention.
The exception to this standard is category E85 Ventilation support. Codes within this category must always be assigned when ventilation support is performed in either an inpatient or outpatient setting.
PCSE5: Invasive ventilation with tracheostomy (E85.1)
When a tracheostomy is performed for invasive ventilation the following codes and sequencing must be applied:
E85.1 Invasive ventilation
E42.3 Temporary tracheostomy
How must a gastroscopy be coded when described as ‘failed intubation’, i.e. when the scope only enters the mouth and the patient is unable to tolerate?
When a patient is admitted for a gastrointestinal tract endoscopy and the patient is unable to tolerate the scope and statements such as ‘failed intubation’ is documented in the medical record; the procedure must not be coded.
G20.1 and G46.2 classify endoscopic coagulation of bleeding lesion of either oesophagus or upper gastrointestinal tract; when would these codes be assigned?
Answer = When coagulation of bleeding lesion(s) is performed using haemostatic spray as a therapeutic procedure. These codes must not be used to classify coagulation as a means of haemostasis at the end of a procedure.
What does new standard PCSG6: Endoscopic insertion of nasogastric or nasojejunal feeding tube (G47.5 and G67.5) tell us?
Answer= The endoscopic insertion of an NG or NJ tube must be coded using the appropriate code with the addition of code Y76.3 Endoscopic approach to
other body cavity.
What must be coded when banding of haemorrhoids is carried out in conjunction with an endoscopic procedure?
When banding of haemorrhoids is carried out in conjunction with an endoscopic procedure,
both H52.4 Rubber band ligation of haemorrhoid and the OPCS-4 endoscopic procedure code must be assigned.
What must a coder be mindful of when coding a colonoscopy that does not progress beyond the sigmoid colon?
The exclusion at categories H20-H22 indicates that when a colonoscopy does not progress past the sigmoid colon a code from H23-H25 must be assigned.
How must a failed or abandoned ERCP be coded?
Answer = A failed or abandoned ERCP, (i.e. an ERCP with incomplete insertion of the endoscope, or complete insertion of the endoscope but the ampulla cannot be cannulated) must be coded to J43.9 Unspecified diagnostic endoscopic retrograde examination of bile duct and
pancreatic duct.
What is the sequencing of cholecystectomy and ERCP when performed together?
Answer = When endoscopic retrograde cholangiopancreatography (ERCP) is performed at the same time as cholecystectomy, the ERCP
must be coded in a secondary position.
What sequencing must be followed when a coronary artery procedure involves the insertion of a combination of stents?
When a combination of drug eluting and metal or plastic stents have been inserted during a coronary artery procedure the following codes and sequencing must be used:
• body system chapter code describing the insertion of the drug eluting stent
• a code from category Y14 Placement of stent in organ NOC to classify the
insertion of the other types of coronary stent(s)
• a code from category Y53. Approach to organ under image control or Y68.
Other approach to organ under image control to classify the method of image control used.
What is coded when an angiocardiography of the heart is carried out during the same radiology/theatre visit as a coronary arteriography?
When an angiocardiography of the heart (codes K63.1 K63.3) is performed with a coronary arteriography (codes K63.4 K63.6) during the same
radiology/theatre visit, both procedures must be recorded.
A code from category Y53. Approach to organ under image control or Y68. Other approach to organ
under image control must also be assigned in a secondary position in order to classify the method of image control used.
Why must a code from category K65 Catheterisation of heart not be assigned in addition to codes in category K63 Contrast radiology of heart?
Because catheterisation is implicit within these codes.
When must the codes within principal category L71 Therapeutic transluminal operations on other artery and extended category L66 Other therapeutic transluminal operations on artery be used?
They must be used to code interventions that are not classifiable at fourth character level within named artery categories (L01 L63).
What subsidiary code is also required when coding procedures classified to these two categories and why?
A site code from Chapter Z must also be assigned as the categories L66 and L71 are not site specific.
If a procedure cannot be classified at a specific fourth character within L66 and L71, what must be used?
The .8 and .9 subcategories at named artery categories, e.g. L63.8, L63.9 etc. must be used instead.
What code range must the coder use when an artery or its branches is not specified at the category or code description or at the category inclusion?
Answer = Where the artery is not specifically referred to within the code description or inclusion, a code from categories L65 L72 must be used instead with the addition of a site code from Chapter Z where available.
If the artery or its branch are listed as an inclusion what subsidiary code must the coder ensure is also assigned?
A site code from Chapter Z
What must be coded when an angioplasty/
venoplasty and insertion of stent are performed at the same time?
When angioplasty/ venoplasty and insertion of stent or stent graft are performed at the same time and individual codes are available for the angioplasty/ venoplasty and for the stent/stent graft insertion, only the code for the stent/stent graft insertion is required, because the angioplasty/ venoplasty is implicit within the stent/stent graft insertion code.
PChSL4: Removal of bypass grafts
The removal of bypass grafts must be coded to the original operation bypass category with the fourth-character .8 plus code Y26.4 Removal of other repair material from organ NOC unless there is a specific fourth-character code that classifies removal of the bypass graft.
PCSL1: Anastomosis without a site specific code (L16-L28 and L48-L63)
Anastomotic sites that are not specifically indicated at the fourth-character level within categories L16-L28 and L48-L63 must be assigned to the .8 within the relevant category.
What do coders need to bear in mind when coding aortic aneurysm repairs?
Whether the repair was carried out as an emergency or as an elective procedure.
How is a change of ureteric stent coded in OPCS 4.9?
Answer = A ureteric stent is coded according to method used to change the stent e.g. cystoscopically.
PCSM1: Percutaneous drainage of kidney (M13.2)
Code M13.2 Percutaneous drainage of kidney includes the insertion of a nephrostomy tube for drainage. The insertion of the nephrostomy tube must not be coded in addition.
When extracorporeal shockwave lithotripsy of calculus of ureter is performed via cystoscopy and a stent is inserted, what must be coded, and why?
Only the code M31.1 Extracorporeal shockwave lithotripsy of calculus of ureter is required as the cystoscopy and the insertion of a stent are integral parts of the procedure. A code from Y53 Approach to organ under image control or Y68 Other approach to organ under image control must be assigned in addition.
If the stent is left in situ following the lithotripsy in order to facilitate the passage of fragments of the calculus, then the stent insertion would
require coding in addition.
PCSM6: Catheterisation of the bladder (M47)
Urethral catheterisation (M47.9 Unspecified urethral catheterisation of bladder) must not be coded when; • catheter insertion is performed routinely as part of, or following, a procedure • catheter insertion is performed to keep the patient comfortable during admission, for example in an elderly immobile long stay patient.
Neither must subsequent removal of the catheter be coded in these instances.
If a patient is catheterised for urinary retention the insertion of the urethral catheter and its subsequent
removal would not be considered a routine part of care and both the insertion and removal
of the catheter must be coded.
If a urethral catheter is inserted routinely, but following removal the patient is unable to void urine, this indicates that the patient is in urinary retention. The reinsertion of the urethral catheter, and its subsequent removal following reinsertion, would not be considered a routine part of care and both the reinsertion and subsequent removal of the catheter must be coded.
How must a failed TWOC be sequenced?
When a patient is admitted for removal of an indwelling urinary catheter or trial without catheter (TWOC), and on removal the patient is unable to void resulting in the catheter being reinserted, this must be coded using the following codes and sequencing:
M47.3 Removal of urethral catheter from bladder
M47.9 Unspecified urethral catheterisation of bladder
PCSP1: Refashioning of episiotomy scar (P13.8 and S60.4)
Refashioning of an episiotomy scar is coded using the following codes and sequencing:
P13.8 Other specified other operations on female perineum
S60.4 Refashioning of scar NEC
PCSP3: Episiotomy to facilitate delivery of terminated fetus and subsequent repair (P14.9, P13.2, P25.5)
Where an episiotomy (P14.9) is carried out to facilitate delivery of a terminated fetus, this must be sequenced in a secondary position to the delivery code (Q58 Delivery of terminated fetus).
The subsequent repair of an episiotomy is included within code P14.9 Unspecified incision of introitus of vagina and therefore must not be coded in addition.
The exception is where the episiotomy has extended to a perineal or vaginal tear. In these cases, P13.2 Female perineorrhaphy or P25.5 Suture of vagina must be assigned in addition, to classify the repair of the tear.
When a procedure has been performed for a pregnancy with abortive outcome what subsidiary code must also be assigned?
Y95 Gestational age.
How must an intrauterine coil procedure and hysteroscopy be coded when performed during the same theatre visit?
Where an intrauterine coil procedure (insertion, replacement or removal) is performed
during the same theatre visit as a diagnostic or therapeutic hysteroscopy, the hysteroscopy
code must be sequenced before the intrauterine coil code.
When would a code from category Q58 be assigned?
When it is documented in the medical records that the responsible consultant has delivered a medically terminated fetus that is either liveborn or showing
no signs of life.
PChSR1: Coding deliveries (R17-R25)
All deliveries (except for deliveries following a termination of a pregnancy), regardless of the number of weeks must be coded as follows:
- A code from categories R17-R25 must be assigned in the primary position.
- Code R24.9 must only be used for a normal vertex delivery, when no other code in categories R17-R25 describing the delivery applies.
- If on type of delivery method is used and subsequently changed to another type, only the method used to successfully deliver the baby must be recorded.
When coding caesarean sections:
- Assign a code from R17 for caesarean sections performed when the patient is not in labour.
- Assign a code from R18 for a caesarean section performed when the patient is in labour (and for all emergency caesarean sections)
When coding multiple deliveries
- Each different type of delivery must be coded with the most serious sequenced first
- Where all delivery methods are identical only one code is required.
PCSR5: Episiotomy to facilitate delivery and subsequent repair (R27.1, R32)
Where an episiotomy (R27.1) is carried out to facilitate delivery, this must be sequenced ina secondary position to the delivery code.
The subsequent repair of an episiotomy is included within code R27.1 Episiotomy to facilitate delivery and therefore it must not be coded in addition.
The exception is where the episiotomy has extended to a perineal tear. In these cases, a code from category R32 Repair of obstetric laceration must be assigned in addition, to classify the repair of the perineal tear.
PCSR6: Gentle cord traction for removal of retained placenta
Gentle cord traction performed to remove a retained placenta forms part of the management of ‘normal’ delivery and cannot be classified using OPCS-4 codes.
Looking at the standard PCSR7 how are obstetric scans classified to categories R36 R43 carried out?
Codes within categories R36–R43 must be used for day cases and inpatients when the patient has been admitted solely for the purpose of a procedure/intervention.
When two or more obstetric scans classified within categories R37.- Non-routine obstetric scan for fetal observations and R38.- Other non-routine obstetric scan are performed during one scanning session, the following codes must be assigned:
R37.2 Detailed structural scan
Y95.- Gestational age
Procedures classified to categories R36-R43 are always carried out using ultrasound therefore a code from category Y53 Approach to organ under image control or Y68 Other approach to organ under image control is not required to identify the method of image control.
